Important Information

How it Works

In order to address these grounding hazards, we want to stop current on the grounding conductors.

Using the example in this diagram, we have a grounding mat.

The NCB is placed between that grounding mat and the wall outlet grounding conductor. There’s a resistor in there, and it stops the current from getting to your grounding mat.

And – VITALLY– the NCB maintains an effective “ground-fault path.” You may not know what that means, but it’s really important. Because, if for some horrible reason an electrical cord is cut or something else goes wrong, and your grounding mat gets electrified, the NCB activates and sends that current back to trip the breaker immediately– protecting you.
