[QUOTE="Rob Timmerman, post: 145918, member: 172"] Re: Correct feeder cable for distro Any number of things could cause that to happen, including inadequate ventilation, magnetic coupling, or excessive current. And it's worth remembering that there are losses in wire that generate heat. A 100' length of 12/3 with 20A through it will dissipate about 120W of heat due to resistive losses alone. A single-phase run of 2/0 with 200A through it dissipates a touch over 600W. That heat has to go somewhere... [/QUOTE]
