30 AMP OPS

[Pete Masterson]

Gregory,

I followed your explanation except for the part quoted below. The 30
amp 220 circuit in my home that I "stole" for the coach originally
served an electric stove (or oven, I forget which -- we converted the
house stove to natural gas). So what I don't understand is why the 30
amps available would be only on one leg or the other but not both?
The circuit is served by two breakers (switches tied together with a
metal bar) and wired with a red, black, white and green wire. White
is neutral, green is ground, I thought the black and red were each a
30 amp "leg" of the circuit -- or am I missing something. (I'm not an
electrician, so "three phase" wiring isn't my area of clear
understanding.)

As for the cheater cable idea, it sounds like it's likely more
trouble than it's worth. My coach is "all electric" (no LP gas), so
when I've been in a park with 30 amp power, I've unplugged and turned
on the generator to use the cook top -- figured I'd blow the 30 amp
circuit otherwise. (It is a little inconvenient.) It might have been
nice to use the cheater to create enough power for the cook top, but
I'd guess that the 30 amp and 15/20 amp circuits use the same leg
(black or red) from the park power supply, and therefore wouldn't
gain me anything (but a headache and possibly an upset park owner).
