disposal wired direct.

[stew]

Any restriction on direct wiring od a disposal with nm emerging from the sheetrock under the sink? Seems ok as long as its not subject to damage but just curious what others think.

Its doable, as long as 422.31 can be satisfied.

Probably nothing wrong, but I would not do it this way. I like to use a handy

Box w/receptacle for disconnect means.

 

[stickboy1375]

Yeah, i generally install a cord if one is not already on the unit. but, i've done it both ways...

If you wire it direct without a local disconnect means then you'll have to put a lock-out device on the breaker. The plumber will curse you if and when he comes to service the unit and then you have the problem of explaining how to reset a breaker or use a lock-out device to a HO. Pant load of fun.

this is actually an exisiting install. The home inspector called it as exposed romex. have to go look at it. but if the romex isnt hanging all over the place I cant see a problem either.

I always wire it direct but I afford some small protection by sleeving the nm with carflex. I realize carflex is not protection from damage but what could you possible do under a sink for that to be an issue. I have seen many use just nm but I don't like it. I guess it is an AHJ call.

 

[stew]

well the AHJ may call it but what code section would he be able to cite?

I thought that was already discussed. 334.15(B)-- protection from physical damage

How many disposals have you seen that don't have a switch right near the disposal? Does the user have to turn breaker on when they want to use it and then turn breaker off again when they are done?

There has been debate on this forum before as to whether or not a decora switch that does not have on/off marked on it is an acceptable disconnect, but other single pole switches are marked.

Plumbers and breaker lock-out devices are never used in the same sentence.

What if it's a batch feed type disposal ? No separate switch is required.

Good point !!!
