"Roy, I'm curious about the 30/15 amp adapter. You say not to use the kind without the cord. What makes them different? I remember you posting somewhere they can overheat, but why do these overheat and the one with the cord doesn't? I'm sure they are all made in China under the same great QC guidance of all products made there that we've all know and come to love. We've used the the short ones for about 20 years and haven't had a problem. However, if I knew why they're a danger, I'd switch. Is there something that makes one better than the other?
Thanks! "
There isn't any problem using an adapter that has a UL rating for the amps you need for 120 and normally 15 amps. If you draw 15 amps ,yes they will get warm.
The poster with the lights at 1.5 amps, yes that is at 12 volts but you are converting 120 volts to 12. = .15 amps of 120v.
The poster using romex with ends on it, just go away, this is not a safe or legal thing to do.
To the poster, I always have a couple of 50' 12ga cords with me. You will then ALWAYS have enough to carry a load from a 20 amp breaker.
Just remember with electricity always look for the UL listing on the product, even at home with all the stuff from China. UL has been the bench mark in America for years.
