Two dryers on one 220v circuit?
When I moved into my house it came with a washer and dryer in the basement. I would like to install my washer and dryer (from a previous house) on the main floor to make doing laundry more convenient.

I would also like to leave the ones in the basement hooked up for doing really dirty loads that my wife doesn't want to mix with regular laundry (or a backup if the others fail).

What I need to know is if I can splice the existing 220v line to the upstairs location or if I need to run a new branch circuit. Normally I wouldn't put two appliances on the same circuit like this, but I'm thinking that since they are both electric dryers, and they will never be on at the same time- it shouldn't be a problem.

It is legal, but WHY bother? IMO it certainly IS likely that they might be used at the same time. Do you have kids? :whistling2:

I would run a new cable instead of introducing a splice point in a high draw circuit.

I would love to be able to use two dryers at the same time. The wash cycle is much quicker than drying the clothes. I think you will find that you will use both even if you don't plan on it.

Thanks everyone- I guess I'll go ahead and throw in a new branch circuit. If nothing else, when I sell the house someday, the new owners may not remember to only use one at a time :wink:

The other thing you have to remember is that you will have to use 4 conductor cord plus 10-3 NM cable this is only way you can add this per code requirement.

This above comment is used for electrique dryer.

Is gas an option?

Not only does the wire size limit the amperes rating (and the breaker rating) for a circuit but the kind (shape and prong arrangement) of receptacle and the appliance(s) itself (themselves) have maximum circuit amperage ratings.

The plug on the appliance cord also implies a maximum circuit amperage rating, and you may not cut it off and substitute a plug rated higher.

A definite no-no. "Each dryer requires a 30 amp circuit so I will run one 60 amp circuit daisy chaining to two dryer receptacles."

That would be a total code violation. The poster needs to run a new 30 amp circuit for the second dryer.
