View Full Version : disposal/DW shared neutral

I'm helping a past client troubleshoot an electrical problem and am wondering if anyone has any advice.

Shared 3+1 leaves the panel for the DW and disposal. At both appliances there is a single 2+1 coming from the wall. So, where's the junction? J-boxes must remain accessible, right? Is there a standard place or way an electrician might wire this? Could the box be behind the cabinets (I'm thinking this wouldn't be "accessible" but who knows).

Problem is there is no neutral continuity at the DW but there is at the Disposal so it seems very likely it's disconnected at the junction in question. This is the middle floor of a newer condo unit so I can't imagine the box is above or below.

I'm stumped (easily done sometimes).

Sounds like there is a JB somewhere. Could be hidden or just not in an obvious location.

It maybe spliced in the Disposal switch box

Good call...... can't believe I didn't think to check that.

I would look behind the DW also.

Matt,

A picture is worth a 1000 words. Your description is to vague.

Please define what you mean by a 3+1. Are you speaking of a 12/3 cable connecting to two tandem 20 amp breakers with joined handles?

Or even better, what is the issue you are trying to repair or identify? Will you please attach some picture of the install.
