Hardwiring Dishwasher

[JoeNorm]

Can I hardwire a DW under the 2020 code? Is all that is needed a lockout on the breaker? I need more characters so I am continuing to type

Wire it either way.

You can find plenty of characters here in the forum, just keep reading.

Oh, you mean typing characters. Sorry.

Thanks for reading.

I've seen it discussed various ways, 210.8(D) requires the OUTLET that supplies the dishwasher to be GFCI protected. If you run the NM straight to the dishwasher connection point... is that considered an outlet ??
Locally inspectors require the breaker to be GFCI.

I've never heard that one before, that's funny!
I'm more familiar with"....jumping out of the frying pan and into the fire".
That fits my personality very well,... at times. Sometimes I have two mouths and only one ear. Say's my wife. True. She's the brains.

Augie, you have been here way longer than me. The "outlet" discussion has been done more than once in my time.

From 2017 NEC Outlet. A point on the wiring system at which current is taken to supply utilization equipment. (CMP-1)

So yes the connection of the romex to the dishwasher is the outlet.

Did you mean dual function breaker, or is 210.12(A) amended out in Tennessee?

Art. 422.5 does not mention plug in or hardwired so gfci is required regardless

422.5 Ground-Fault Circuit-Interrupter (GFCI) Protection for Personnel.

There was a homebuilder that I used to do work for years ago in Orlando. I think it was David Weekley Homes. They had a single-pole switch drawn on every plan as a dishwasher disconnecting means because we hard-wired all of the dishwashers.

I put a switch (toggle type) under the kitchen sink and then run directly over to the dishwasher unless its a Bosch or some other fancy foreign unit that insists on a plug in via a secondary box araingment they annoyingly supply with their dishwashers. The gfi protection is done at the panel with a dual purpose afci breaker.

My error.. yes dual-function... TN has some added exemptions to AFCI but dishwashers are not among the exceptions.
