#11862, "RE: Regarding wire Guage for amp power" In response to In response to 10

Skin effect is for AC voltages or frequency based signal tranfer. NOT DC POWER
and brands of wire makes a HUGE difference also.
and I can get 8 awg wire that you can twist into a 1 inch circle and I can get 8 awg that needs at least 1 foot circle to bend.
go to 4 awg wire and you will benefit.
I was talking to a NASA engineer yesterday who was hooking up a 120 Amp 48VDC DC fuse panel with 24 awg wire because he thought it was the voltage that generates the heat and that his 24 awg wire says 300 volt on the side of it so he thought thats plenty to support the 48 volt supply to the panel. No matter what I told him he thought he was right. I had to go over his head and call up his boss to avoid serious safety hazards caused by his believing he knew what he was doing.
