NEC 110.14 and highly stranded wire on oven

[tom baker]

That would be a listing and labeling issue...only permitted if the manufacturer has specified that method of termination for finely stranded conductors. At one time SquareD had an instruction that showed wrapping the finely stranded conductors in copper foil for terminating in set screw connectors. Not sure if they still say that.

I have seen copper foil on generator fine stranded terminations.

Right, the grey top ones, see post #2. Anyone know how they differ inside from the normal black top ones?
