The ground conductor of an AC power cord should be at least the same gauge as the current carrying conductors in order to provide an instantaneous, low-impedance path to ground.

The resistance of 6 feet of 8awg is .004 ohms. The resistance of 6 feet of 14AWG is .015 ohms. An added .011 ohms or there abouts is not going to allow for the circuit breaker to blow in due time with 120AC on it??
Ok, It looks like I may have gotten that one incorrect. Not totally sure and I don't understand all the issues. Lots of equipment has no ground wire at all. Tweaker
