Question on putting an outlet under the sink


I'm adding an airswitch for my new disposal. The previous disposal was lid-activated and wired directly into the disposal.

My new disposal has a plug and I need to add a GFCI outlet under the sink. The wiring that comes from the floor into the base cabinet under the sink is flexible armored cable (BX). I want to mount the outlet/box on the back of the base cabinet (that is, I do not want it to be recessed). What type of box should I use? Any other suggestions?

Thanks!

Use a handy box. No GFCI required.

Question on putting an outlet under the sink


Is that all that's required? I was worried about moisture getting into a metal box.

It should not be wet under the sink.

GFCI is not required, but also not a bad idea.

Question on putting an outlet under the sink


I'll reiterate, WHY would there be moisture UNDER the sink???
A GFI is NOT required, and IMO is not needed.

I would use a 4" square box with a raised finished cover. We call them "industrial" covers. The on in Brric's picture is way to small to do anything with, especially if you are set on using a GFI.

Question on putting an outlet under the sink


There isn't any moisture under the sink right now, but I was just thinking about what if the sink starts to leak or something--wouldn't I want a GFI there?

Can I put a 3-prong outlet (non-GFI) to attach to the BX cable?

Thanks!

If you're worried, buy an outdoor rated box for a few dollars more.

It was just an illustration. I wouldn't use a 13 cu inch box either. Deeper handy boxes are available.

Of all the places in a house that aren't supposed to be wet, the cabinet under a sink seems to be the one that gets wet most often for me. Drains and disposals leak, shutoffs leak, countertop spills run down through cracks, dishwasher drain hoses leak, etc. And when it does get wet under there for some reason, it often requires that someone work down there while it's wet. I hate being under a wet, leaking sink to fix it - even more so when my face is next to a wet receptacle and garbage disposal. I've done that a couple times. A GFCI there would give some peace of mind. Also, the metal garbage disposal chassis is directly connected to the metal drain ring in the sink. The grounding conductor SHOULD provide adequate protection, but it doesn't hurt to have a backup. As the guy who both works on sinks and changes receptacles in my rentals, I've put in GFCIs whenever I've replaced a receptacle under a sink unless it's a switched split for the dishwasher and disposal.

I would also use a box that can't easily get any water in it.

This is the reason why I thought of using the GFI. Thanks for the help, folks. I ended up putting a GFI in a 4-in deep handy box with a plastic cover because I couldn't find any of the metal ones that fit a GFI. Then I plugged the airswitch and disposal in and everything is working.

Thats the box and cover Id use also,by the time you stuff wires and a plug in one of those handy boxes theres really no working room.
As far as the gfi goes just the fact that its under a sink surounded by plumbing seems like a good reason to use a gfi to me,anybody whos ever been stuck on their back halfway under a cabinet trying to run a snake down through a ratty old san-tee will tell you about moisture under a sink!
And if moisture is the only reason to install a gfi why do all the other areas of the kitchen that arent around water require them?

You did use clamps to bring the wiring into the box, right?
