Install 2 breaker box under sink with one 15 amp breaker for DW. The previous owner did His own work and HACKED it all ! Pull service cover . I always do this. Pull each wire to breaker to make sure, Wow one arcs and pulls out !tighten. Wiggle each breaker, Bingo 20 Amp disposal and D.W. cracked ! Pull it charred real bad ! Replace.

I never heard of putting a "2 breaker box" under a sink for a DW and disposal.
Do you mean a duplex receptacle?

I can't tell from your post what exactly you have or what happened, but it sounds an awful lot like a MWBC. Maybe the neutral came loose or someone took it apart not knowing what they were doing.

Those two appliances may be able to be on the same circuit. If cord and plug connected they must both be under 50% of the branch circuit rating. Many times this approach will work for a 20 amp circuit but not a single 15 amp circuit.

If they are "hardwired" it could complicate the required disconnecting means a little but they wouldn't need to meet the 50% rule if no receptacle outlets are on the circuit.

2014 NEC we have GFCI requirements for the dishwasher, and for any receptacle(15/20 amp 125 volt) within 6 feet of the sink - including any inside a cabinet.

You profile has you listed as a lic. Gen. contractor CA. Does this license allow you to do electrical service calls?

I was just making comment.
You write in such broken words it's hard to tell what you are talking about.
I really could care less what you do.

Have a nice time in the wine country

It is amazing how people have been doing this for 50 years and don't have the correct terminology and can't troubleshoot a basic multiwire circuit or even ask the right question.

Why? If you suspect there may be a bad neutral (on the service side of things) why not verify it first? Put some load on it and make it show itself, preferably some resistance heat type of loads and not electronics that may not like what happens if there is a problem, then call them if there is a problem.

Why would he want to do that. He's a veteran expert, he know's what he's doing and been doing so for 50 years....:thumbsup:
