I believed that the "only one conductor per terminal" rule was all-encompassing, but in reading 110.14(A) Terminals (2002NEC), it mentions "Terminals for more than one conductor...shall be so identified".
One of my co-workers says that when wiring in a main panel, he terminates the grounded conductor and the grounding conductor of the same circuit under the same screw on the terminal bus, if there are no separate GND and NEUT bars.
Is he complying with the NEC in diong this?
Are terminal bars in breaker panels "identified" or rated (listed) for two conductors under each terminal (screw)?
Started doing this myself, but, not sure of the integrity of both wires having same pressure, and remaining securely attached.
