Grounded neutral


What is a grounded neutral and how do I prevent it? I was reading that some AFCI breakers have problems with grounded neutrals, what exactly should I be looking for?

well, by definition, a neutral is a grounded conductor so, a neutral is a grounded conductor by design,


so, that means, to me, you don't want to prevent it.

the only thing I can think of is a neutral that is grounded some place other than the only place it is allowed which is at the main service disconnect.

that's why I am confused why my instructions say check for grounded neutrals.... because even at the service panel neutral is bonded to ground so its basically the same thing

This is why things like this should NOT come with instructions.

Make sure the branch neutral is connected to the AFCI and the AFCI white wire is connected to the neutral bar in the panel.

OOHHH!!! I get it now, I think.


It sounds like a very poor instruction but typically, the neutral from the circuit will be connected to the neutral bar which in the main panel, is also ground i.e a grounded neutral. As corsair states, the circuit neutral must be removed from the neutral bar and connected to the breaker. The neutral from the breaker will then be connected to the neutral bar.

Of course it says check for grounded neutrals right after it tells you how to connect it and even shows a diagram of the branch circuit being wired to the breaker and the pigtail to the neutral bus.... anything to confuse people

I had to hang an Italian sconce that wasn't agreeable to American boxes. The instructions would have been great if I spoke Italian. This experience has led me to the belief that the more you pay for a fixture, the harder it will be to install. This relationship is inverse with fans.
