Plug Wiring Reversed?
I just bought a house and the inspector tagged four of six basement
outlets as hot/neutral reversed. I open the first two, see the problem, and fix it (one of two blacks was going to silver and one of two whites was going to brass). However, the other two "bad" outlets are already wired correctly (white to silver/black to brass). Plus, these two outlets have one set of wires (white/black/ground) instead of two sets, which may not be a problem, but could be a clue. Supposedly, if I switch the wires, the plugs won't be reversed anymore. But that would put white on brass and black on silver. Maybe the electrician got the white and black wrong at the head end, wherever that is. So switching the two at the plugs will be the right thing to do. If the inspector was right, what is wrong with the wiring and how do I fix it? If the inspector was wrong, how could that be, as he was right about two other plugs in the same room? Or do I need to spend a couple of bucks on a sensor to check for myself whether the inspector was right? |

my dad can wire recpts backwards

It sounds like you need to buy the gizmo. If the wiring was crossed anywhere you have the potential for a "back fed" neutral. If the color code was followed meticulously through the entire circuit you will not have a problem. Sounds like some home wiring went on at some time. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Keep the whole world singing . . . . DanG (remove the sevens) "Niel" wrote in message om...

It's possible that the outlet you fixed was upstream of one or both of the other miswired ones and all is not well. If not, it's possible that the outlets that test reversed are fed from upstream outlets whic are miswired for the wiring feeding those outlets. --- sam | Sci.Electronics.Repair FAQ Mirror: http://repairfaq.ece.drexel.edu/ Repair | Main Table of Contents: http://repairfaq.ece.drexel.edu/REPAIR/ +Lasers | Sam's Laser FAQ: http://repairfaq.ece.drexel.edu/sam/lasersam.htm | Mirror Sites: http://repairfaq.ece.drexel.edu/REPAIR/F_mirror.html Note: These links are hopefully temporary until we can sort out the excessive traffic on Repairfaq.org.

Or do I need to spend a couple of bucks on a sensor to check for myself whether the inspector was right? Just buy one of those cheap things you plug into an outlet. It has 3 neons in it that can quickly find common wiring errors. Some versions also have a button to create a leakage that should trigger a GFI outlet or circuit breaker to trip. They are only a few bucks and well worth it. I've found reverse wired outlets in apartments I've lived in. Reverse wiring will not affect many basic items with non-polarized plugs, but could create a hazard for items with polarized plugs or grounded plugs that assume hot is on the narrow blade. Lamps are now wired with polarized plugs so that the neutral is wired to the shell of the bulb socket, and the hot to the center. -- If there is a no_junk in my address, please REMOVE it before replying!

I had an inspector report that all of the outlets in my house were reverse
wired. It turned out that in fact they were three-wire outlets with no ground wire. The house was built back before ground outlets were standard, so they are all wired with two wires. Someone later replaced all the original two-wire outlets with three-wire ones. Although this creates a false sense of safety in that there is no protective ground, it is apparently legal because you can't get two-wire outlets anymore. An electrician I consulted said it would be too costly to put in modern 3-wire wiring because of all the demolition - the old wiring is stapled inside the walls and can't just be pulled out as the new wire is pulled in. So I had him put in GFCI outlets and breakers where needed for safety (bathrooms and kitchen) and let the rest go. -- jhhaynes at earthlink dot net |

As someone else said, it is legal if they are GFCI outlets. But how many of those installed in the real world are on GFCI? I've lost count the number of times I've seen someone install 3 wire receptacles in non grounded houses, a lot of times the houses don't even have a GFCI at all. Certainly adviseable to add, though not everything will work right on them. I've seen a lot of computers and a few microwave ovens that would trip them regularly. |

And if you don't know how to use it please don't be messing with this stuff, call an electrician and let them take care of it for you. |

To find which wire is Hot, measure it to a solid ground like a water pipe. Neutral is Dead, White, and Silver, like the bare Safety Ground. Put a 200 VAC voltmeter, or DMM set to that range, from Hot to Neutral, this should show 120VAC. Then from Hot to Ground, you should again see 120 VAC. The hot should be 120VAC to EITHER of them separately! If not, then Hot is not connected to the "hot"!!! Try neutral to both each separately, see if it is BOTH 120VAC to ground and also the black. If so then the neutral and hot are switched and should be switched back at the bus. Of course, use insulated probes, rubber gloves if you are dim-witted, and switch off the breaker when you change things.

I don't know how they apply your way. Here, you should get a licenced electrician to check out all your wiring. It is possible that it was originally wired up by someone unlicenced. If your house catches fire as a result of faulty wiring and there is a possibility that it was wired up illegally, you may have problems claiming insurance. Henry Australia |

If the inspector was right, what is wrong with the wiring and how do I fix it? Swap black and white at both ends. This involves working on your breaker panel, which is dangerous. I recommend hiring an electrician. If the inspector was wrong, how could that be, as he was right about two other plugs in the same room? He'll only be wrong if he mixed up his results after making measurements. Or do I need to spend a couple of bucks on a sensor to check for myself whether the inspector was right? That's what I'd do. And don't let the erroneous situation persist. |

This involves working on your breaker panel, which is dangerous. I recommend hiring an electrician. That depends on how the breaker box is wired. Most, if not all modern breaker boxes have the main breakers and the breakers for the individual circuits in the same box. Since this is presumably an old house, that may not be the case. It may have the main breakers or cartridge fuses in a separate box, and there may be an external lever to power down the whole house. If that's the case, the breakers can be switched off one by one and the main power can be switched off. At that point, there is no power coming into the breaker box. |
