What about a lockout on the breaker.

IMO a 208 volt 40 amp commercial DW is likely going to require a disconnecting means within site per 422.32.

IMO most commercial DWs are motor driven appliances.

What about it?

That section is right above the section that says accessible.

So yes it can be behind that front cover, but once you open that cover you have to be able to access the outlet without pulling out the DW.

Who says that it is not accessible if it is behind the unit, the section does not say "readily accessible". If you need to be with in sight of the disconnect that is an additional consideration, it does not mean the plug is the only means of disconnect and can not be behind the unit.

In my opinion the inspector can.

Accessible (as applied to equipment) Admitting close approach; not guarded by locked doors, elevation, or other effective means.

IMO a inspector could say that having to remove the DW to 'access' the receptacle means that the receptacles placement does not allow 'close approach' and guards the receptacle by 'other effective means'.

A disconnecting means that can not be accessed is useless.
 
The last time I wired a commercial dishwasher setup I mounted 3 stainless steel 600 V rated disconnects on the wall adjacent to the dishwasher. (for the dishwasher, pre-heater, and disposal) :cool:

I agree with you about the disconnecting mean is useless behind the unit. All I am saying is a plug behind the unit is not necessarily the only means to disconnect the unit. If there is another way to disconnect the DW I don't think it wrong to connect the unit with a cord and plug.

I agree, but the code section that allows using a cord and plug on a dishwasher is also the same section that requires the receptacle to be accessible.

most dishwashers can be pulled out by removing 2 screws in the top front.

I don't mean to throw a wrench into this thread but once you install those two screws isn't the unit considered to be "fixed in place" ? Also, bear in mind that in 422.16(B)(2) ALL 5 conditions have to be met. If anyone knows how to slide a dishwasher into a tight space with a 3'-4' cord and plug attached to it would you please post how you did it ?
I see receptacles behind the dishwasher frequently. Personally I think it is a bad place for it , but I don't see it as a violation of 422.16 B .

I always thought it was a good idea because I figured that the probability of there being an electrical issue would be far less than if there was a plumbing issue. Having a local disconnect means would make it safer for the plumber to service the unit. On the other hand, if one of us had to perform electrical service on the unit we would make damn sure that the power was turned off by any means possible. I can't say the same for plumbers. (And please, if any of you have dual licenses I didn't mean this as a personal attack - just observations over the years). And, if the disconnect means can't be readily accessible or within sight then the lock-out feature on the breaker (as Dennis suggested) is the best way to go IMHO (But that usually counts for squat !!!)
 
There was a thread on this earlier and I believe Celtic brought up the fact that if a cord and plug were to be used for the dishwasher then it had to be an approved cord. Let's open up that can...or not. :grin:
