[QUOTE="tyromeo55, post: 3580506, member: 1719"] To add to this... To add to DH's post. This is a good simple test but not absolute. If one of the terminations is not good but still making some connection you could be getting a good reading but still not able to deliver any current. The neutral (grounded conductor) only carries the unbalanced load. depending on what connections are intact and what is running on the the other phase then little to no current could be flowing thru that neutral. It would be really sketchy just like what you mention when the grinder comes on. Be warned. depending on what you turn on and the impedance between phases you could get some really nasty voltage spikes on the entire system. the poor neutral is also probably getting really crunchy too. Could be a fire hazard if you keep going. [/QUOTE]
