Your very welcome.Chris that helped alot. This has been the most confusing thing to me in the NEC. Thanks.
It is a tough one. I just need to open up my mind a bit. Thanks Chris. Does the MH book help with the understanding?Your very welcome.
I think alot of the confusion comes from the fact that a lot of people equate Class 1,2, and 3 systems with "low voltage" when in fact Class 1 circuits for the most part operate at nominal voltages up to 480 volts.
