Re: Applance Disconnect
I believe 422.31(B) permits the branch circuit breaker to serve as the means of disconnect if it can be locked in the open position.

Re: Applance Disconnect
Remember if it is a convection oven (containing a motor), you must have a disconnect within sight.

I have been taking pictures of the dishwashers in different units that I am inspecting. It is curious that some of these new electronic units do not have "off" buttons. They have a button labeled 'power'.
What do you think?

Re: Applance Disconnect
Pierre, I don't see a lot of wiggle room.
422.34 Unit Switch(es) as Disconnecting Means. A unit switch(es) with a marked-off position that is a part of an appliance and disconnects all ungrounded conductors shall be permitted as the disconnecting means required by this article where other means for disconnection are provided in the following types of occupancies.
If it doesn't say "OFF", it doesn't count.

Re: Applance Disconnect
Honestly Pierre I have always thought that allowing a unit switch to be a disconnect is cheesy.
I was under impression a disconnect should kill all power to a piece of equipment not simply turn it off.
The first guy I worked for taught me this way, everything is either cord and plug connected or gets a disconnect switch. At dishwashers we would install a switch at the JB under the dishwasher.
It looks like a 'power button' does not meet the rules.

Re: Applance Disconnect
So.... it sounds as if you can install an oven with a plug, even if the plug is hidden behind the unit, and even if there's no switch that says 'Off' as long as the oven's not a convection style...long breath...AND...there's a circuit breaker acting as a disconnect for the unit. Yes?
Whew...

Re: Applance Disconnect
Now we're splitting hairs. Everyone with half a brain knows that when you work on the range, washer, dryer, etc. you pull the unit out and unplug it. If you don't then you get what you have coming to you. You can only do so much to protect the stupid people from themselves. After that, they're on their own.

Re: Applance Disconnect
Those pulling units (ovens, ranges, dischwashers, etc.) with non-permanent wiring from installed locations shall recall all past jolts prior to state of confusion currently enjoyed when forgetting to unplug said unit.
Paul, perhaps we can do more! Proposed language addition to NEC 2008.
Art.xvii(B)(1)(c) Permanently Wired Appliances and Half-Cephalics

Re: Applance Disconnect
Article 100
Guarded. Covered, shielded, fenced, enclosed, or otherwise protected by means of suitable covers, casings, barriers, rails, screens, mats or platforms to remove the likelihood of approach or contact by persons or objects to a point of danger.
My take:
If the intention of the placement of something is meant to reduce access to the receptacle then it is considered not accessable. If the intention is lacking then the same situation is considered accessable.
I don't write this stuff I only try to understand it.

Re: Applance Disconnect
Regarding a disconnect for a hard wired dishwasher,most of the ones that I know of are located on the wall above the counter along with a light switch which controls the light over the sink as well as a third for a garbage disposer.
Now let's see, without turning off all three the one for the D/W is unidentified and most likely never used and probably forgot what it was for anyway.

Re: Applance Disconnect
It's kind of strange that 422.33(B) requires that the receptacle be accessable with out the removal of the range but 422.16(B)(2)(4) and (5) allow the very same thing and give it as an option for dishwashers?

Re: Applance Disconnect
Sparty,
The disconnect out-of-sight direct wired wall JB to H2O heater residential connection still varies by the AHJ's. Using an energy conserving 'Little Gray Timer' box in residential is also allowed as a disconnect at the heater unit.
