electrical hookup for a garbage disposal
 
It didn't come with a plug, and I didn't install the box for on yet.

any reason to not just hook it up direct?

None.
Make sure you use a clamp where the wires going the dishwasher.

I NEVER hard wire residential disposals. I always put a 3' appliance cord on and a single receptacle under the sink to facilitate removal/service.

If the only reason is for service or replacement;

I cant say I've ever had to service a disposal apart from spinning it with the allen wrench maybe once every 2 years. I guess my parent's contractor grade unit went out after 25 years, and I went a little higher grade than that. seams like I'd have to replace it 4 times before I'd wish I had put in a plug the first time. I don't think the house will last that long. its looking a bit shaky in areas after the first 90 years.

It's not just the unit. It makes it MUCH easier to remove in case you have to work under the sink or replace a faucet, etc.
Why do you think most of them have quick release mounting rings?

DOH! I saw disposal and wired a dishwasher!

I have seen both, but it is much batter wire cord and plug.

If you choose to direct wire your disposal, you will need to add a breaker lock at the panel for the disposal. This allows a service tech to lock out the disposal when servicing in it. This is actually the code for all direct wired appliances (ovens, dishwasher, etc).

Although, if the switch is a single-pole, is rated for the load being switched and is indicating (labeled off/on), that is acceptable as a means of disconnect a well.

Thanks for all the advice guys.

I'm not 100% decided yet. My main worry when I was first thinking about it was vibes and solid wire not mixing, but I guess that isn't much of a concern.

looks like I will be routing the bulk of the drain maze behind the disposal, so that is making me learn toward the plug.

1 more quick question; am I correct in thinking that you do not put a disposal on a GFCI protected line?
I believe I read somewhere that there was a code exemption for disposals and washers on the GFCI requirements around water because the plugs are hidden away and electric motor loads tend to falsely trip them.

Not required to be gfci protect.

new code
 
New Code here in Philadelphia, now we install a switched recp. under sink for disposer and a recp. for the dishwasher. you can split the recp. top switched bottom hot all the time for the 2 appliances. Now you will need cord sets to plug in.

thats what I did (splitting the outlet) at my last house. all the extra wires and connections sure fill up a single box pretty quick, especially with 12 gauge. I'm sure we'll see a code against that soon enough.
:whistling2:
in this house, I put the dishwasher in a decent distance from the disposal.
I added the disposal because I had to redo the drain.

I ended up finding a cord that would work (old microwave cord I saved for some reason) and installed the plug.

I guess the main thing was how much it galled me to have a "high-end" disposal not come with a cord, and then have HD try to sell me one for $12 or whatever it is.
:furious:

I certainly would not have bothered removing a cord to direct wire it.

there is a code for box fill, sounds like your box was too small.

it was a standard box. It probably just seamed fuller bending all of those wires to shove it in. either way, I'd use 2 separate boxes or 14 gage next time.
