Fwd: Dangerous way of getting 220V from 110V outlets
In article , Robert Casey says...
http://www.quick220.com/index.htm It's even patented. There's a serious shock hazard here. If you have a load plugged in its 220V socket and turned on, and you pull out of the wall one of the extension cords, you will have a male power plug with a hot prong waiting to shock you. Right next to the ground prong of that plug. (snip) For those who do spark-stuff, this was kicking around the antique radio ng.

Not necessarily. There is an interlock built into it. They say " [its] safety interlock blocks all power to the 220 volt outlet until electrical connections are complete and correct." Probably is a relay since it consumes 4w. Bob |

Fwd: Dangerous way of getting 220V from 110V outlets
In the first house I built back in 62 I ran 3-12 conductors to all of my kitchen outlet boxes which gave me two 110V circuits at each box on either side of the neutral. My sears RAS ran like a pig on 110V so I always ran it on 220V. In order to do that I made up an extension on which I literally cut the 110V male plug down the center and pulled my 220V by plugging in to the hot side of each of the two outlets in the same box. As long as you did not plug the saw into the extension there was no danger of shock. You had to be careful not to unplug from the wall with the saw switch on and of course there was never any need to do that. Bill D |

Technically, the AC voltage of the two outlets are 180 degrees out of phase. Practically, you find the "independent outlet" by moving the second power cord to different outlets until the green light on the front panel goes on. About half the outlets in a building will be "independent" of the other half. __________ R, Tom Q. |

I would sort of object to your implication that you "understand
that stuff" In the case of many smaller (4000 to 5000 watt) generators, the 110 circuit comes off some heavier wire on the lower side of the circuit, the 220 comes off that cirucuit plus some smaller wire on the upper side.

Do any small 120v generators actually use a CT 240v transformer to provide their 120v? If so, I'd think they would come equipped with 240v outlets as well. Otherwise, why add the extra weight and expense of a transformer? R, Tom Q. No transformers involved. The inexpensive "Contractor grade" 2KW to 4KW generator plants use a center-tapped 240V winding on the alternator to provide two circuits of 120V. That makes the end shell simple, two duplex 120V receptacles and a couple of cheap thermal circuit breakers. It would raise the cost to add two more circuit breakers and another receptacle for 240V, and these units are designed to a price point. If they were selling the exact same generator plant overseas they would leave the center tap disconnected to get straight 240V, and place the proper receptacle for that countries power plugs on the rear shell of the alternator. Or a set of connection lugs in a hardwire hookup box (with a lid to keep wandering fingers out), and leave it as an excercise for the user to make an adapter cord. -- Bruce -- -- Bruce L.

The "Inspector" would let them away with a two fuse 30A disconnect 'service panel' fed by two #10 wires in 3/4 conduit. I don't recall how they handled the meter, which at that time, went between the main disconnect and the fuse panel. The stuff hit the fan a couple years down the road when people started getting used to having electricity and bought a few appliances, such as electric stoves.

You pays your money and you takes your chances. Dick The 220 breakers are dual, and break the entire circuit. But you have to assume by the site that the box attempts to prevent that. Bottom line is this unit is for people afraid to open their circuit box and do the job right. |

Fwd: Dangerous way of getting 220V from 110V outlets
"Larry Jaques" wrote in message ...
Also, in older homes (60's on back), all the outlets are on one leg and all the lights on another. That box will never work with any home using that style of electrical scheme. In newer homes, the balancing is better, but most rooms have only one leg connected to the outlets. You'd have to string extension cords (hence their modus operandi) to other rooms every time. Not too cool. My bogus gadget meter is pegged on BOGUS! I don't know. For instance, I am in the process of wiring my shop, and its very tempting to say you will only use one phase in there. After all, you could get across two plugs. However, that would also defeat the idea of ballancing the load there, and make it that much more likely that you will trip a breaker while operating that nice arc welder. |

That's an interesting comment Scott. I have oh so often heard people speak of balancing the load. What are the concerns about this balanced load issue? Bill D |

It looks like it's "creating" 220v by using the two 120 legs of a typical US house 220v residential service. That wouldn't be the case with a generator that only creates 120v. Yes, but from a small generator that is wired that way, it works. Had to use the one-plug-on-each-circuit method, and warned the people about how it works. If they kill themselves, I said the mandatory "Kids, Don't try this at home!" ;-p has anyone checked out the differential in the 4400w vs 3300 watt U.S.A. plugs? 80.00(!), ouch. i wonder if the insides are any different for the two models? my old standby, total rube and very unsafe, method looks pretty good by comparison (just wire 220 to a 15a 110 jack, paint it red, and change the plug on the 220v gear to match). --Loren NO! Do NOT do that, use the right plugs and receptacles for permanent uses. Someone who can't read (or just plugs in without thinking first - even you!) is going to blow something up. The whole yes, exactly, _me_! after years of using it i plugged my shop vac into it. it immediately sucked onto the concrete floor so fast i could not move the wand. duhhhh...., as i was yanking the cord the motor started sparking and smoking. next time, i will also paint the jack red and install a cover of some type with further warnings. reason behind changing the plug configurations is so you can't plug in to the wrong voltage. Where the heck are they charging those prices? You must be shopping in the wrong places, with people who think that "Manufacturers Suggested List Price" is only a starting point... "Builder's quality" 15A 120V duplex receptacles are under 50 cents each in quantity, but even the fancy "mixed duplex" with a straight-blade 20A 120V on top and a 20A 240V on the bottom are around $10 - $12. Even smaller twistlock receptacles are under $20. $80 is up into IEC pin-and-sleeve receptacle territory... -- Bruce -- yes, agreed, and even lower grade plugs get pricey in 20+ amp 240v configurations, one of the reasons i have done the rube 110-240 thing. not that i would recommend it... remember that you have to buy jack _and_ plug. i have worked most of my adult life with computers/computer rooms, and am consantly amazed at the prices of "Stoval" plugs and jacks, and at how many are just scrapped when the equipment is retired.

That's an interesting comment Scott. I have oh so often heard people speak of balancing the load. What are the concerns about this balanced load issue? If the load is balanced, there's zero net current in the neutral leg. That almost never happens in practice, of course, so the neutral leg has to be sized to handle some net current. In a completely unbalanced case, it has to be as large as either of the hot legs. Balancing the load doesn't actually reduce the required size of the neutral because the Code requires it to be sized for the fully unbalanced case. Of course if the load is completely unbalanced, then you're only using half of the main breaker. If you balance the load, you get to use both sides of the main, and can draw up to twice as much total 110 volt current as you could if it were totally unbalanced. Note that every other breaker in a row in a normal entrance box is on the opposite leg. So just filling the rows with equal size 110 breakers automatically balances the box. Of course any 220 breaker is automatically balanced since it connects to both hot legs. Gary |

That's an interesting comment Scott. I have oh so often heard people speak of balancing the load. What are the concerns about this balanced load issue? If you're going to run several 120v machines at once, you try to balance the current draw between the legs so you don't pop breakers. For 240v, make separate runs from separate breakers. When I removed the 240v baseboard heaters in this new (to me) house, I had several spare breakers. I ran 3 lines for the larger shop equipment (all WW) in 3 areas of the shop and it worked fine. The table saw, bandsaw, dust collector, and lights are all on separate circuits. -------------------------------------------------- I survived the D.C.

Thanks Larry, and Gary!!
Your posts set the record straight. The reason I asked is that somewhere in my dark past I was told that it was for reasons of economy. The reason being was that the meter *was said* only to read current through the high side and that value was simply doubled in calculating your usage. Meaning that if you were to only use one side at any given time then you true usage would be exactly half of what you were being charged. (so that is just a fable) So thanks again Bill Larry Jaques wrote: On Sun, 26 Oct 2003 05:59:16 -0500, Bill brought forth from the murky depths: Scott Moore wrote: However, that would also defeat the idea of ballancing the load there, and make it that much more likely that you will trip a breaker while operating that nice arc welder.
