Can I change a 220v outlet to 120v and use existing 10awg wire
 
I have a dedicated washer/dryer circuit running to my daylight basement.

30amp 220v breaker.
10awg wire.


However my plans are to install an all in one condensing washer/dryer that required a 120v circuit of at least 10amps. (No decent way to vent a regular dryer)

Can I change my outlet and breaker and keep using the 10awg wire?

Or do I need to come off something else in the bathroom that is already 120v?

Everything but the bathroom is enclosed so running a new wire would be pretty rough.

I will be talking to an electrician about this but wanted to get an idea of what I will need to do.

Thanks!

It would not be against code to use #10 on a 15 or 20 amp circuit. You might need to pigtail some #14 or #12 to get the wire to fit a receptacle properly.

As a laundry area, the 120v circuit needs to be 20amp and the receptacle must be GFCI protected, if you are in the USA.

Absolutely you just can't go any bigger that a 30 amp single pole breaker.....does your existing wire have a ground....aka 10/3

For a general use receptacle, the circuit can't be larger than a 20 amp circuit.

@dabearsjoe420 - Thanks, yea the wire is 10/3 - Red, white, black, ground.

The appliance says minimum 10amps so a 15a or 20a breaker should be good right?

A 15 or 20 amp is fine.
