Switching Neutrals

[johnp]

Dealing with a conflict of opinion. Does the NEC state that the neutral cannot be switched except in auto. transfer systems? I believe that it does but can't find where in the NEC.

Re: Switching Neutrals

You can switch the neutral if you switch the ungrounded conductors at the same time.

Why you would want to I have no idea, other than a transfer switch.

Iwire,
there was a very good reason to do that but i cannot recall what it was. maybe someone else would know.

Re: Switching Neutrals

johnp I just saw your other post about switching the neutral on motor starters.

I do not believe 404.2(B) applies to this as it is common practice.

I understand the neutral must be disconnected in the emergency shut off for gasoline dispensers.
