Last night while adding circuits to a 200a panel i found that someone had fed a second panel by terminating the feeders on the main lugs of the first panel.The feeders to the second panel are smaller and warm to the touch.I didn't have time find the distrobution breaker to check It's size.I asked around and was told that just because the wires are warm dosen't mean it's a problem.I'll have to check it with the IR gun tommorow.thanks
You are telling us that you found conductor insulation hot enough to the touch and did not investigate further?
That to me alone, would ring alarm bells.
You'd better hope that them wires don't get any hotter, this is how building fires start.
It is not a IR gun you need, it is a clamp meter.
Having said that I would have cut the supply to that place before things got much worse.
