I am looking at a commercial dishwasher to use in my home. It is wired for 208V 60HZ 1PH. I know it does not match my home voltage. Would it still work or what would I need to do to make it work? Thanks.

Typically that's wired between the two hots and ground off a 220v two phase circuit. I have a 3.5 HP 60 gallon air compressor wired like that in my garage.

Question... WHY do you want a commercial dishwasher unit in a house?

Well, I have 14 children (and no, we do not have our own show). Dishes are a big part of our day.

Congratulations (?)

First, you really need to have this conversation with the local authority having jurisdiction.

The inspectors there will probably have to give you a variance to use a commercial dishwasher.

You would need to provide a plan to the inspectors to show them how you will derive the 208 V and the correct amperage for the device. Also, the plumbing to and from a commercial dishwasher may be different from what you currently have.

Then you have the hot water and pressure that you need. You may need to install a hot water tank for the dishwasher. I'm not sure at all about the plumbing, but you would be wise to have those answers before you submit your plan to the inspectors.

A 208 volt appliance may not work properly on a home electrical system, which is 240 volts.

Before attempting this, contact the manufacturer of the unit to confirm if the unit will accept 240 volts.

If your looking at new, then try to get a 240 volt unit, if the unit is used, then confirm before purchasing.

Well... actually in a typical home it is 120/240v, not 220v. And it is single-phase, not two-phase. And it is NOT 208V between the two legs, it is 240V.


A 208V unit will probably work, for a time. The higher voltage will eventually hurt the motors and heating element due to the higher voltage. Also, the heating elements will run hotter. This may be an issue with insulation and nearby components.
For instance, a 2000W element rated for 208V will run at 2662W @ 240V. That is quite a bit of a jump.

I will also say, this will NOT be a code complaint installation since it is being installed outside of it's rating and manufacturer's specs.

WOW! 14? Really? That is impressive and crazy at the same time. LOL :D
