Breaking The Neutral..GENNY INSTALL

snapperhead

i have a generator tied into my house panel and a disconnect switch to isolate the pole legs coming in 2-115V...220V across. my question....should i break the neutral coming in also even that it goes the grounding bar that all the house neutral(whites)come back to from the loads within the house sockets.i work on 230/460 3 PHASE equipment for a living HVAC field. basiclly thinking the Gen neutral will feed up the pole into the utilities lines???? when running

I just went through all of this with my sparky yesterday. His opinion was to check the neutral for stray current and then forget about it. The box should be grounded according to NEC and, if any strays are produced, they should go there before going back up the line.

Hard to understand everything you said.

Basically the transfer switch you buy decides whether or not the neutral is going to be switched.

If the the neutral is switched then you'll need to bond the neutral to the ground at or before the transferswitch on the gen side(only one place though)

If the neutral is not switched, it's a pretty standard hook up, black to black and so on, and make sure you ground and bond everything correctly.

I'd rather suggest that the generator you own most often dictates whether you buy a transfer switch that switches the neutral. Not all generators give you the option to bond or unbond the neutral ground connection at the genset.

Can't the two be bonded at the first point of disconnect?
