There's not even a requirement that a garbage disposal must have a switch, but it would be a good idea to provide one.

So what about a disconnect? Go ahead and provide one. It need not necessarily be a switch. Most people puts cords on disposers, nowadays. There is no specific requirement for a switch.JOHNEO99 said:

Not necessarily. For quite some time, disposals were made in what was called "batch feed" operation. You removed the stopper, put in the food, then replaced the stopper and gave it a twist to start the disposal.
However, I don't think they're all that common anymore.
Just watch out for this pitfall:

The air switch idea is something that they had used on hottubs which is also a good idea since it does not place the user in contact with an electrical switch while being in the water,

The air switch may be cool but it is something else to go bad that will be expensive and a hassel to change out. The wall switch is my vote.
I am not sure what size motor a disposal has but aren't there requirements for motors with certain hp to have a disconnect. I put a disconnect on all motors , fans etc.

The air switch unit plugs into a receptacle, The wall switch is great till the owner installs the sink in an island...
It's an opinion for the HO to make as being expensive... for me just something else to sell them...

The problem is that the plumber usually is the one that supplies the disposal with the air switch (at least around here) but when it doesn't work I have to go service it. Yes it is more money but I would rather not have the headaches. The only one I ever wired I got called back because the line got kinked. I got enough to do without those call backs.

Who said you had to go back if the plumber supplied it? Do you do service calls for garbage disposals also?

If I wired the unit and I get called that it isn't working then it may be an electrical thing. At that point I would say call the plummer but I still have to check it out. I also find it hard to charge a good customer for a service call who just spent 30,000 dollars on their electrical. It like a warranty thing. I know many have no problem charging but I usually don't under the warranty period.
Disconnect?
Disconnect?
You don't need a disconnect for a garbage disposal unless it is hard wired...just like a dishwasher. See NEC 422.33 (A). For cord and plug connected appliances...an accessible plug and recepticle shall be permitted to serve as the disconnecting means.
