i saw mention of this on another message board and its giving me pause.
Can someone please explain, in simple terms, the theory of derating of the wires when there are more conductors in a conduit or raceway than there should be?
I understand higher temps mean lower amp carrying ability of the conductor.
I understand that the sheathing of the wire (conductors)
is rated for a certain temp. I understsnd the danger of crimping the wire.
Is this something we should be delving into as Home Inspectors???
I mean, beyond noting the obvious “super crowded” conduit filled with wire, where do we draw the line?
