We had a brief discussion in my alternating current principles class last night. The instructor was convinced that all grounded conductors at a receptacle location had to be pigtailed in order to not break the grounded path. Obviously, that's the best way to do the wiring at the receptacles, but is it necessary by the NEC? I only see this rule applying to multiwire installations where breaking the neutral could do serious damage to an appliance (like a PLASMA TELEVISION) if ever broken.
Comments?
