    Question: My 5th Wheel has a 50 AMP power cord. We have an adaptor cord which allows us to plug into 30 AMPs when 50 AMPs is not available. Why do the two pins and sockets on either end of the short reduction cable either melt the rubber or turn the pins a copper color? The Ground pin and socket looks like new. Are the wires in the reduction cable 30 AMP or 50 AMP rated? If 30 AMP rated, why is the adaptor cord UL approved? Shouldn’t the wires in the cord be 50 AMP rated? Where can I get a reduction cord from 50 AMP (female) to 30 AMP (male) with 50 AMP rated wires?
