Hi, guys,

Question for those knowlegable about electrician and code type stuff..

I have a situation where there we are wiring what is, in effect, a
transfer switch which will connect external 120VAC/60Hz power to two
sets of loads (sort of like the 240VAC/center tapped situation in a
home) OR a pair of 2kW inverters.

When external power is supplied by a line cord, the neutral and ground
are effectively tied together, however once the line cord is
disconnected the ground (chassis etc.) and the inverter neutrals are
tied to each other, but floating with respect to the ground.

Are there safety or "code" (not sure any code really applies to this
situation when it's unplugged and far away from any power lines)
issues with letting neutral and ground float wrt each other in an
inverter power situation from an electrical wiring point of view?



Best regards,
Spehro Pefhany
