Dishwasher circuit size 15A or 20A?

[al]

Has anyone seen a household dishwaser requiring a 20A circuit? The largest one I have come across is an LG with a 12A namplate current.

In have yet to see one. But when in doubt we just run #12 wire to cover all contingencies.

I see them all the time requiring 50 amp 3 phase 208 circuits.

Better run 6/3

I see them all the time requiring 60 amp 3 phase 208 circuits.

Me too, just not a "household" version.

I guess it depends on the house.

An electric dishwasher costs you less in the long run....:wink:

Especially if you try to get rid of it and it has little d/w`s

I hooked one up recently that required 3 circuits. One for the pre-heater, one for the internal heater, and one for the motor. All 480 volt, 3 phase.

I always run #12, this way any residential model they pick out now or in the future should be satisfied. I would hate to have to rerun the circuit.

Is the dishwasher named Jim?

I will run either a separate 15a circuit for each the dishwasher and disposer, or a single 20a circuit for both.

I recently ran a single 20a for two disposers and a dishwasher in a kitchen remodel.

If its electric hope it gfci protected.And yes it has produced a few other dish washers. of lower quality.Got mine from the hills of KY off a tabaco farm,keeping her too.
