Not necessarily, your circuit breaker would trip if theres something pulling more power than the breaker is designed to flow. The breaker is supposed to trip if there's a short or over-current but the insulation could melt before one of those things happen.

You really should have a heavier cord if yours is getting hot.

Just sayin

If his cord got close to the point where it would melt copper, I guarantee he would be pulling more then his home breaker (usually 10 amps, sometimes 20) can allow through it.

You're way beyond help if the copper is melting. The danger starts when the insulation melts.

If he's using some crappy 16ga cable then it would be very possible for it to get hot enough to melt insulation.

Reminds me of my computer when I didn't realize I tore the -12V connector out of its socket in the 24-pin.

WOW! Hot! Hot! Hot! Everything was hot. It was just scortching. Before I realized it, I happened to be in the BIOS. Flipped to the Thermal tab and...what??!?... 74C?!?.... I never hit the power button quicker in my life. I could have made eggss on just about anything in that computer.

Even the cables were burning hot for some reason...Apparently we do need a -12V. Okay, this was completely off topic.

Definitely use a thicker gauge power cable . I'm using a 10 gauge rated to draw 15A at 115V.

wow.. Shortly after my last post i shut down the cable and replaced it with a thicker one.

This thicker one doesn't even get warm

i was looking at the rateings of the smaller one and it says "250v 10A max"

i dont believe that one bit.

I have a 585W power supply. lets assume WORST case scenario i was using 585W.. (giving it 100% efficienty)


250 * 10 = 2500W

The cable was getting hot at 585W yet it claims to be rated at 2500w..

why dont i believe that..

Current makes the cable hot, not wattage. 10A is probably optimistic if it was getting hot at only 3A.

Your outlet is 120VAC... not 250v.

Worst case on a 585w PSU would be more like 730w assuming 80% efficiency.
