Electrical Troubleshooting: 30 amp disconnect wiring



Electrical Troubleshooting Question:

I'm putting in a 30amp disconnect with 10/3 AWG cable with a ground wire.

The disconnect is a signal phase with a ground and no neutral bar.

Can I float that neutral and pass code?

Carl.

Hi Carl - Great Electrical Repair Question!
What is this disconnect being used for, or what is being fed from the disconnect?

If the neutral is a spare as with most all 240 volt loads that do not require a neutral, then you could simply cap off the neutral.

This is not true for all 240 volt devices however, such as the following equipment:
Electric Dryer
Electric Range
other equipment that requires a dedicated or separate neutral wire.
