ECN Forum Forums Code Related Discussion NEC & other Code issues Disconnect for dishwasher?

For a piece of equipment that has to be moved in order to service it, I cannot imagine the switch on the appliance qualifying as the disconnecting means.

Tom:

"We put a 1900 box (4x4) under the sink with extension rings thru the cabnet. Then we run the wips to that an put on what ever garven is needed."

Please explain the above (1900 w/extensions)???

'Lockable' CB's are the norm......

Redsy:

Had a discussion about the 'breaker lock' devices at a CEU meeting/class, with a few AHJ's. Seems that one don't like the 'lock-out' type, as he feels it's not a permanent item! To be continued 1st week in March at next CEU.

BTW, I have not seen a switch, either above or below the counter.

Hotline,

Look here:
The QL1PL and QLPB123PL snap very securely on to the CB and require a screwdriver to pry them off.

Read 422-31 & 422-34 2002 NEC

Wow, disconnects for residential dishwashers! I've never seen one in Arizona, they are always plug and cord connected. We always rough in a split wired duplex for the DW/DSP.
But then, we keep our circuit breakers outdoors also!

Redsy:
Thanks for the link. I was not the person debating, but the 'referee' (part of the team doing the CEU)

I believe he was refering to the type of lock-off's that are part of the lock-out tag-out kits similar to the one's available at WW Grainger. I commented that if the item is not 'easily' removable, while not being 'locked-off, I would not make an issue of it.

Further, if it is 'factory' installed it should be accepted, as long as it's not been modified, hacked, altered, etc.

This discussion will probably continue during the next CEU 5 hr, 1st Friday in March.

How do you interpet the section 422.34 ( 2002 NEC)?

I do exactly as BigB does. I install a pre made appliance cord on the disp and DW and then plug them in.
I keep my breakers inside though

I accept it all of the time

Ryan, I accept it all the time when the switch says ON/Off because UL explained to us at one of the UL meetings they have at the IAEI Section meetings, that the switches marked ON/OFF do indeed disconnect the branch circuit from the appliance. Now if it says STOP/START it doesn't qualify as a disconnect. That's the measureing stick I use.
