Formidable Shared Neutral Wire

No current means no voltage across the switch s power supply which means full voltage on the disconnected neutral wire.

Shared neutral wire. Therefore if this wire has voltage that means it s doing its job. With the neutral connected the current to supply the switch electronics will flow normally from phase2 through the switch electronics and back into the shared neutral. I was pulling a new phase wire for dual switching t8 s in a canadian tire and a co worker asked me if it would be ok to share the neutral of another circuit.

A multi wire branch circuit two hots from different phases sharing 1 neutral is often found in the kitchen where it powers one receptacle which has the jumper connecting the upper and lower outets removed. Go to the electrical panel and switch off the breaker. Although the current in a shared neutral may be almost zero when the loads are balanced it is important to use copper cables that can carry currents during a load imbalance.

These can often be found in older properties where the stairway light. And in the case of the smart light switch the neutral wire also provides power so that the switch can always be on. The result is that you get two 15amps circuits at one receptacle.

I just had to find out a little more. Basically two hot wires are sharing a neutral wire. But be careful this obviously indicates that you have not killed the power to the switch you re working on.

I gave a reasonable answer but i was incurred with curiosity. At the panel both breakers should be bonded together so it is not possible to have one on and one off. We discussed earlier that the primary job of the neutral wire is to serve as a pathway for energy to return back to the original source.

The shared neutral wire is also called a common neutral wire and this arrangement is known as an edison circuit. The shared neutral will easily take the current and there will be very little voltage on it. When neutral wires of two or more separate circuits are connected at other than the main panel the electicity has multiple return paths resulting in net curr.
