Breakers compatible with Federal Pacific Stab-Lok Load Center
Hi all. I want to replace my existing Federal Pacific Stab-Lok Load
Center breaker box because the reports that I've heard about it scare me, and I want to rewire my whole house because the old wiring scares me. I have a replacement plan in mind, and before I bring in someone that knows more than I do, I'd like to get as much lined up as possible. I plan to install a 100amp breaker into my existing FPE (200 amp service) box to service a new breaker box (also 200 amp service), then rewire the house to the new box, and because of other reasons we will be moving the incoming service to the new box. Note: I say "we" but in this case "we" means electricians and the electric company as far as they need to be involved. Anyway, if anyone is familiar with the FPE Stab-Lok load center, I'd appreciate some advice about the 100amp breaker. I've found the NA2100 (Type NA, 2 poles, 100 amp) breakers, but I'm not sure if this is the one I need for this breaker box or not. My existing breakers are type NC. Apparently the type NB breakers bolt in ("B" is for "Bolt" obviously). I have found several of the 30amp or less breakers as type NC, but anything over that seem to be type NA. I just want to know if the NA2100 will work in my box...or if you need more information to make that determination. Thanks, Charlie |

I wouldn't replace the FPE equipment out of fear of fire. I would replace it simply because it's garbage. I believe the difference between the NA and NC is that the NA, possibly because of it's 100 amp rating stabs into four places on the buss, as opposed to just two |

I _believe_ all NA and NC are allowed in any FPE panel that takes one or the other, but the real answer is on the sticker on the inside of your panel -- it will list the allowable breakers it accepts. I'm assuming this is intended simply as a temporary feed to the new panel? Be sure you use adequately-sized cable to feed it -- don't try to "get by" w/ something too small just because it's temporary and short-time expected... -- |

My guess is that they don't make half sized double pole breakers in the larger sizes, like 100 amp. In any event the 2/100 NA will fit in the panel in a location where you'd install four full size single pole breakers, two on each side of the buss |

Yes, it's only temporary. Rather than replacing everything at once, it will let me rewire the different circuits as I can, and would ensure minimal downtime when it comes time to move the service to the new box. The old FPE is history after that. Thanks for the response. -Charlie |

RBM,
You're correct that it's listed inside the box...I found that after I'd sent this question to the group. It accepts NA, NC, & 2B (whatever that is?) breakers. And yes, I've spoken with an electrician and will be using 2 gauge 4 conductor (2 hots, 1 common, 1 ground) copper from this breaker to the new breaker box. Thanks a bunch. Charlie |

I think it's a waste of time and those FPE breakers are more expensive than other brands. Many service changes to single family houses are done in a day. Unless there is some other reason to temporarily feed a new panel I suggest that you start talking to qualified electrical contractors about what you are trying to accomplish. If you don't want to swing over the old circuits to the new 200 amp panel, have the electricians run a feed from the new panel to the old panel thereby making it a sub panel. |

It might be cheaper, and certainly less trouble, to deal with your fears. There may even be a twelve-step program available. |

Actually I have spoken with a couple electricians, but they mostly just agreed that what I had planned would work and was a good way to approach it. I guess that my idea was the reverse of what you suggested...make the new panel a sub- panel, rewire, then switch the service. Moving the service and then making the old one a sub-panel I think is indeed a better approach. It'll be much easier to find the appropriate 100amp breaker for the new panel, and I'd certainly trust it much more than another old Stab- Lok double-pole breaker in the FPE breaker box. Thanks for the new approach. Charlie |

YOU WILL NEED A NEW 200 AM SERVICE DROP and meter can.erhaps its me
but one step is easier. or install the new main panel and feed each new breaker to a feed in the old FPE box, after stripping out all the old breakers and hardware. just use the old box as a pass thru. i have thought about doing that at a home, since the wires are too short and a garage door track obstructs the area,. better one pass thru box than 10 or 12 junction boxes.eater smaller less work |

About your plan to put a 100-amp breaker in the existing box and feed a 200-Amp box from that: I suspect pulling 100 Amps through one breaker will melt the stab-on bar. I'd replace the existing box with a new, 200A one. You won't have to splice wires either. |

The Stab-Loc equipment is "LISTED" with Stab-Loc breakers only. Replacing the Stab-Loc breakers with any other make of breaker results in a combination "NEVER" evaluated by the Listing Agency. In fact, the result could be worse than the already existing latent fire/electrical hazard. -- |

In fact, the result could be worse than the already existing latent fire/electrical hazard. I think what the OP wants to do is install a new, non-fpe panel and TEMPORARILY feed it from the old panel with a 100 amp breaker. There is no 100 amp stab-lock breaker made to fit the load side of that panel. There is no 100 amp breaker PERIOD made to fit the load side of that panel. The 100 amp bolt-in is for the service side of the panel. An electrican would likely temporaitly feed the service breaker of the new panel directly from the service breaker of the old panel. I assume this is to allow the old circuitry to continue to run untill the new circuitry is installed and connected to the new panel... Might actually be better to install the new panel FIRST, and connect the service to it - and feed the old panel temporarilly from the new - 50 amps shuld do it for the short term if you are carefull - and move the heavy loads to the new panel first - - - |

There are at least the UBI replacements available 3rd-party that are certified to have met the applicable ANSI Standard altho these particular ones' manufacturer has not expended the bucks to get the UL listed. It seems I recall at least one other outfit in Canada but it may be that the two are the same parent just the one dealing w/ US and the other Canadian markets; won't swear one way or t'other. The unfortunate thing w/ the UBI is that they are quite expensive in comparison to alternatives for other manufacturers so it may be more economical in the long run to go ahead and swap out the panel anyway. -- |

You haven't looked hard enough. They aren't all that common because most appliances draw less than 15A, so 15A cords are plenty. However, they do exist. Many air conditioners have 20A plugs. The plugs are also available at the usual places. |

Got any listed appliances that have NEMA 5-15 plug and cord sets that are protected according to NEC? Highly likely. The regulatory inspection agency in change of inspecting your home/office probably screwed up! Proof: On a 20-ampere branch circuit, load an extension cord until the current draw approached 20-amperes. It can be done ... and have a fire extinguisher on hand ... because it most probably will burn up ... and the circuit breaker will not trip ... until there is a dead short. -- |

That "Problem" is associated with regulatory inspectors not following NEC properly. It's NOT a NEW problem. Virtually every outlet in the house in the past has been protected with a 15 amp fuse or breaker - and virtually every radio, TV, lamp, and small non-heating appliance has had a 16 or 18ga cord - whether or not it has an internal fuse. NONE of the non-fused items are "protected" by the circuit fuse, and if something shorts before the fuse on a fused device, the cord is not protected either. A 20 amp receptacle is CAPABLE of safely handling 20 amps current, and can handle 2 10 amp, or 1 15 and 1 5, without being overloaded. It can also handle a 20 amp device - with its special plug - which a 15 amp outlet cannot - You still can't opperate 2 15 amp devices on the same circuitbecause the CIRCUIT is protected to 20 amps maximum. Im a lot of Europe, each plug has it's own fuse - and a bigger fuse cannot be installed than the plug is rated for. |

As has been point out here many times, the outlet can have two 10A appliances plugged in. Okay, I approached this thread as a joke. I mean, seriously. As you have pointed out, the breaker protects the wiring of branch circuits. That is the primary focus of the breaker since the breaker and branch circuits are the only controllable factors. Once people start plugging things into outlets, all bets are off. With the advent of more and more electrical devices the need for a reasonable compromise in providing more outlets, without dedication, was needed and it was deemed that it was okay to increase the amperage of branch circuits (110-120v duplex receptacles to be specific). The protection and wiring of these receptacles is only to the face of the receptacle. After that, it is up to the user to not be an idiot. The U.L. listing is the rating that a device/cord is tested at, not the rating of what it will be plugged into, nor is it the failure point that the U.L. listed device has. The listing only proves that the device will perform up to claimed rating. That is all. I could go on, but to keep it short and simple I can give an example of something that might surprise some people. Look around your house, place of work, or any store that sells the following: http://preview.tinyurl.com/lubg6n9 Check out the U.L. listing tag near the plug. What does it state? If it is a 16ga cord, like the one shown, it will have 13A as its tested rating. I have a cord, don't know the AWG, but it is only rated for 10A. Ever check out the 7A rating that the power cord that plugs into the power supply of a Desktop? One might think that the ampacity rating is solely because of the wire size, but they would be wrong. Rather, It is the type of insulation versus intended voltage that the insulation type of the wiring is made of. IIRC this is under table 450.5(A) for flexible cords. Anyone ever see a clock radio, with an 18ga cord, rated for 15A? A lamp? I am not going to call "Get it Right", or whatever its nym is, a troll, but maybe it can get this right: How much horsepower is available at a 20A receptacle? Merry Christmas! In business offices where I've installed phone systems, networks, computers and backup power supplies, many of the women(I adore many of them), will plug a 1,500watt electric heater into the UPS and wonder where the smoke came from. There are places where I installed separate circuits just for things like electric heaters and made it clear to the gals that the only place they were to ever plug in a heater was the labeled outlet. Me and the guys have been using white vinyl plastic downspouts to carry the MC power cables, phone and network cables from the suspended ceilings in offices down to the floor. I can pre-build the vinyl power poles at the office before they're taken to the job site and installed. The reason we use the plastic downspouts is because the metal tela-power poles from manufacturers cost close to $100.00 from the electrical supply houses. If someone slams a desk into one of the expensive metal power poles, it can be dented, bent and damaged enough to require replacement. The vinyl pops back into place. ^_^ http://www.cableorganizer.com/tele-power-poles/ TDD |

Hi all. I want to replace my existing Federal Pacific Stab-Lok Load Center breaker box because the reports that I've heard about it scare me, and I want to rewire my whole house because the old wiring scares me. I have a replacement plan in mind, and before I bring in someone that knows more than I do, I'd like to get as much lined up as possible. I plan to install a 100amp breaker into my existing FPE (200 amp service) box to service a new breaker box (also 200 amp service), then rewire the house to the new box, and because of other reasons we will be moving the incoming service to the new box. Note: I say "we" but in this case "we" means electricians and the electric company as far as they need to be involved. Anyway, if anyone is familiar with the FPE Stab-Lok load center, I'd appreciate some advice about the 100amp breaker. I've found the NA2100 (Type NA, 2 poles, 100 amp) breakers, but I'm not sure if this is the one I need for this breaker box or not. My existing breakers are type NC. Apparently the type NB breakers bolt in ("B" is for "Bolt" obviously). I have found several of the 30amp or less breakers as type NC, but anything over that seem to be type NA. I just want to know if the NA2100 will work in my box...or if you need more information to make that determination. Thanks, Charlie I would not bother. Simply get the appropriate replacement panel and do the replacement. Many of the wires will not be long enough to reach your "temporary" location and you will have to make the splice in the old box. And your "temporary" box will be sub panel requiring isolated ground. Of course you will find electricians that are fine with your plan because they work by the hour. If you need to upgrade the service from outside from 100 to 200 you can do that ahead of time. There is nothing that prevents you from connecting a 100amp main to 200amp service. Then replace the panel. If you don't have the money to do it, start saving until you do. It's a one day job if the materials are on site. |

You can't apply a direct or cord connected appliance that is rated for use from a branch circuit greater that 15-amperes and consider it "Protected" according to NEC. I verified it with U.L. I suggest you do the same. With respect to branch circuit protection, NEC is not being practiced as written. -- |

Only after Article 400 can you deviate from for specific applications. A "Listed" device is only "Protected" when applied within it's listing requirements and labeling. If you don't provide branch circuit protection compatible with the "Listed" device listing requirements and labeling, it not "Protected" according to NEC. Subsequently, if you provide 20-ampere branch circuit protection to circuit intended to interface with "Listed" devices, the "Listed" devices will not be "Protected". A single, dedicated NEMA 5-15 receptacle is allowed to be interfaced with a 20-ampere circuit breaker ... but not multiple 15 ampere receptacles. In addition, the steady state current draw on a NEMA 5-15 receptacle should be limited to about 13-amperes (allowing for a 2-ampere margin) according to NEC. A 20-ampere circuit breaker would allow for a 7-ampere margin which would expose resistive components (such as power cords) to over 75% more real power than what they are listed at. The power cord, plug, etc. will burn up under such circumstances, and a fused "Listed" device will not protect the power cord of that "Listed" device. -- |

We will always have fires at X-mas due to "overloading" as long as they ignore the requirements. No one is held accountable. Requirements are not being ignored. You just don't understand UL and NEC requirements. Anyone can submit a code change proposal. And anyone can petition the UL to change their standards. I am sure your proposals will be appropriately considered. |

You are saying that the listing requirements of devices and extension cords with a 15A plug do not allow them on 20A circuits? I see no reason to believe that is true (and it would be absurd). Perhaps a cite? Try 110.2 (approved). "Listed" apparatus is normally "approved" and 110.3-A (examination) would not normally be done. But 110.3-B (used in accordance with listing) is applicable. Fires are likely from not using according to the instructions. The problem isn't the listed device. The problem is branch circuit protection (20-amperes) is not compatible with the listed devices. Subsequently, the listed device is being allowed to operated beyond the parameters for which it was listed (up to 15-ampere branch circuit protection), and creates a fire/shock hazard because the listed device could/does have the opportunity to fail not-safe! Listed extension cords made with #18 wire are readily available. The rating in the NEC for #18 cord is 10A (400.5). According to you, that can't be used on even a 15A breaker. The requirements for overcurrent protection of cords is in 240.5. There are several methods of protection. "Listed" cords are considered protected (240.5-B-3). UL know that cords with a 15A plug may be used on 20A circuits. The system is working as intended. The cord will have a current or wattage rating. It up to the user to use the cord according to the ratings provided. For cordsets that we put together (field assembly), the wire must be #16 or larger on a 20A circuit (240.5-B-4). The NEC rating for #16 is 13A (400.5). The NEC explicitly allows cords rated 13A on a 20A breaker. Got any listed appliances that have NEMA 5-15 plug and cord sets that are protected according to NEC? Highly likely. Yes, it is highly likely. Listed appliance (and lamps, etc) will have a cord large enough to supply the appliance when used as instructed. Cords of listed appliance cords are considered protected (240.5-B-1). Appliances are protected as UL and the NEC intended. The regulatory inspection agency in change of inspecting your home/office probably screwed up! Nonsense. They are enforcing the code as written. Proof: On a 20-ampere branch circuit, load an extension cord until the current draw approached 20-amperes. It can be done ... and have a fire extinguisher on hand ... because it most probably will burn up ... and the circuit breaker will not trip ... until there is a dead short. Your breakers may only trip on dead shorts. Mine trip at the rated current. And I use cords according to their rating. |

Fires are likely from not using according to the instructions. The regulatory inspection agency has the responsibility for 110.3B also .. and they should understand and acknowledge that Listed equipment will be interfaced with such branch circuity protection. As I have already explained, "listed" devices will be "approved" by the AHJ under 110.2. 110.3 (inspection) is irrelevant to listed devices -inspectors do not "inspect" listed devices. They determine that the listed devices are used according to the manufactures instructions and the conditions of listing. You either go all the wall with NEC ... or accept fire and shock hazards as a daily part of life. If done in strict accordance with NEC, fire and shock hazards should not exist. This just isn't happening in the real world! The system is working as intended by the NEC and UL. Anyone can submit a code change proposal. And anyone can petition the UL to change their standards. I am sure your proposals will be appropriately considered. |

replying to Irreverent Maximus , Let's get it right! wrote: nospam wrote: "bud--" wrote in message b.com... I guess this device should be unlisted: http://www.cesco.com/b2c/product/471640 It appears that it accepts both 15 and 20 amp plugs. I wonder why that is? I have shopped at many stores and have yet to see an appliance with a true twenty amp plug. I am so confused... Articles 100 thru 400 of NEC are mandatory. Only after Article 400 can you deviate from for specific applications. A "Listed" device is only "Protected" when applied within it's listing requirements and labeling. If you don't provide branch circuit protection compatible with the "Listed" device listing requirements and labeling, it not "Protected" according to NEC. Subsequently, if you provide 20-ampere branch circuit protection to circuit intended to interface with "Listed" devices, the "Listed" devices will not be "Protected". Cord overcurrent protection for listed cords and appliances is covered in 240.5-B-1 and 3. "Listed" cords and appliances are protected when listing requirements are followed. A single, dedicated NEMA 5-15 receptacle is allowed to be interfaced with a 20-ampere circuit breaker ... but not multiple 15 ampere receptacles. A single 15A receptacle can not be the only receptacle on a 20A breaker. Multiple 15A receptacles are allowed. In addition, the steady state current draw on a NEMA 5-15 receptacle should be limited to about 13-amperes (allowing for a 2-ampere margin) according to NEC. "Continuous" loads (over 3 hours) are limited to 80%. When there are 2 or more receptacles, the NEC also wants an 80% limit. This is not enforceable. And UL does not have that restriction. A 15A load may have a 15A plug. A 20-ampere circuit breaker would allow for a 7-ampere margin which would expose resistive components (such as power cords) to over 75% more real power than what they are listed at. The power cord, plug, etc. will burn up under such circumstances, and a fused "Listed" device will not protect the power cord of that "Listed" device. A "listed device" will have a cord large enough to be adequate when the device is used according to manufacturer instructions. The cord is allowed by the NEC (240.5-B-1). |
