Im trying to figure out how to use 125/250V (3 phase, 3 prong, AC) cable with a 120/240V AC generator. Apparently attachments arent allow for wherever reason, but if you need a better idea of what I'm talking about just say so and ill try to further explain.

i was just in a house built in '58, it has all low volt switches. in the attic there is a relay panels that has a bunch of 3 condutor wires in it and a bunch of relays. tell me how to post a pic and i will has anyone seen this before from that time period?
