In Reply to: I am going to take a 240 v line and split to 2-120v dedicated lines- Does anyone have a site to look up the details on how to do it to code? posted by Carl G on September 22, 2000 at 14:41:45:
Every time you ask a question like that, you start getting conflicting answers. Rather normal... And petew is on the money regarding the electrical engineers vs. the electricians. The engineers may know the amps and microhenries, but they are generally unfamiliar with codes. The electricians, OTOH, do not recognize the engineering lingo, but use plenty of ther own, and generally know how to follow the code.Patricks response is excellent, and also identifies the main problem here - without some specific knowledge one should rather stay away from making dangerous mistakes.
Now, we all hear this and we all do differently. And it is not usually just the matter of money. Often it is because you want it NOW, and it is Sunday. Or you can't stay home all day watching soaps while the sweatty guy is breathing hard in your attic on a 100 degree sunny afternoon.
That is why I change oil in my car. Not because I save money - I don't. My dealer's price is lower (yep, lower..) than what I pay for that $12 cartridge filter plus EIGHT!!! quarts of synthetic oil.
I do it because I don't want the hastle of dropping the car, being driven to work by someone, picking up the car... you know, the usual.
Same deal with wiring. When I remodel a room, I keep moving like a T-34 tank breaching through the German lines at Kursk. I don't eat and don't even have to piss because I sweat all that water away. Last thing I want is to stop and schedule the electrician's visit two weeks in advance, just to wire few sockets. So I just do it. By now I also have pretty good experience.
And then, of course, shit happens. Once my family was having a Sunday lunch, only to be suddenly greated by falling pluster and the lower half of my body hanging helplessly. Next few days were spent applying the feathering coats of mud over this 3' by 3' patch - and I'd rather be watching baseball...
Anyhow, in this particular case, here are my recommendations in order of their preference:
1. Do nothing - one CAN get great results with the "normal" 120V line. You may have other, more serious bottlenecks in your system.
2. Use the Patrick's idea of a huge, and it should be HUGE, transformer plugged into the 240 socket. Something you unplug and throw away if you don't like. As I mentioned before, such units can be found at the surplus places for just few songs. Go by weight and don't buy anything under 100lb.
AND most important: don't listen to EE's tell you how you can do wiring "creatively", that wire is wire, and the currents will be just as happy flowing down that bare ground wire as they will be inside the white-insulated neutral.
