NEC Wiring QuestionIt would seem to me, withOUT searching the code, that the only restriction is that the overcurrent protection scheme provide the necessary protection for the smaller conductor. There may be some restrictions in other product specific standards.

Does anyone out in Cyberland know if the NEC allows 2 wires of different sizes (awg) to be clamped together in a clamping type PC mounted wiring terminal. The wire is striped bare & inserted into a slot on the side of a terminal block that has a screw on top for tightening. I seem to remember the code does not allow wires of different gauges to be clamped together under a single compression clamping terminal. I have searched the NEC and can't find anything on this. Can anyone remember chapter & verse on this issue. If I'm wrong, please be kind, the 60 hour weeks are getting to us. Thanks in advance Michael Taylor Colorado
