Currently adding a washing room and a bathroom in my garage. Should I install a subpanel or use my existing spar breakers.

Always best to use any spare spaces in the Main Panel, and only install a sub-panel when absolutely necessary.

Should I use one breaker for the washer and dryer or washer by itself.

If dryer is 220 volts, must have its own breaker and dedicated line.

Good luck

If the dryer is gas and only needs a 120 volt receptacle,then both washer and dryer can use the one 20 amp 120 volt receptacle and circuit required for laundry area.

The requirements for the NEW fancy front load washers are much higher. I was reading a manual in a store in the past year or so and they recommended dedicated 15 A circuits. I found this on page 1-4 for the Neptune Washers, Maytag Neptune MAH3000AWW - Service Manual which states that the max power consumption is 800 W.

This service manual is being stupid. Just says requires 15A circuit for electric dryer: http://www.servicematters.com/maytag...s/16023110.pdf

If the garage is detached, a sub panel would probably be more cost effective.

National Electrical Code (NEC) requires A twenty amp circuit to the Washer

I might consider a Small 60 Amp Panel in the Garage, so you only take up 2 spaces in the Panel.
You may want to use a Portable Heater, Welder?

My garage is detached. Why would it be more cost effective to install a sub panel.

Yes. You would also need ground rods at your new panel with 4 conductors from your main panel. In the subpanel, neutrals and grounds MUST remain on separate busses.

How far do you have to go?

Will conduit be a problem or would you want direct burial?

You have to go 18" deep.

Thinking of going direct burial. The distance is approximate 20 ft .away from my house.

Reneadvo, it would be great if you explained ALL of the details and ask ALL of your questions at once.

Especially if its detached, Most of the Cost involved is Labor for the trench. Takes the same amount of time, to run 3/4 inch as it does 1/2 inch PVC.
While trench is open I would consider a Conduit for Cable/Satellite, maybe water, Alarm, Phone? That's Just Me. You could even have wire for a 3 way between House and Garage. It can be as Nice or as Primitive as you want it to be. If you ran 1 circuit now, I could almost Guarantee you will want more with in the year? My opinion?
If nothing else, at least use 3/4" conduit.

That's two conduits. One for low voltage (phone, internet, TV, automation systems) and one for high.
