Adding a dishwasher and garbage disposal


We are updating our kitchen cabinets and in the process we will be adding a dishwasher and garbage disposal. Should I plan on having these two on their own separate circuit?

I have a circuit that is no longer in use that I could reroute or I have the circuit that powers most of the lights and outlets in the kitchen.

Many people run a multi-wire branch circuit for the DW and GD. Both sides to one receptacle...one side switched for the GD, one side always hot for the DW.

Also, I don't think lights can be on the same circuit as kitchen receptacles...but it depends on how major your renovation is, so it could be allowed to stay that way for now.

In the county that I work the dishwasher must have its own 20 amp dedicated circuit.

I'm remodeling my kitchen now and am putting both on a single 20A circuit. I've had the same configuration in my last kitchen for years and never tripped a breaker.

Adding a dishwasher and garbage disposal


It can be an electrical nightmare trying to update an older kitchen---a lot more circuits today than the old days,

If the dishwasher installment instruction say delcaited circuit then it have to be it own circuit otherwise you can use with Garbage dispoal gimzo as long it is not over 50% of circuit capacity.

( this apply both 15 and 20 amp circuits unless your local codes don't allow it like Mike's area they will have specfic code on that )

Merci,
Marc

Doesn't always say, and in that case code doesn't specify. I'm not saying it's a good idea!
