Breaker Question

Hardlyable

Right next to my outside service box is a little building (14x14) that the previous owner of my house had built. When the PUD installed his new outside service box he disconnected the power to prevent any mishaps during his inspection. I bought the place in April and I want to reconnect the power back to this building. The wiring itself looks fine, there were two splices that looked unsafe so I installed a couple electrical boxes and rewired them. The outlets are on one run and the lights are on another.

I want to keep them seperate so I was thinking I would hook them up via one double pole 20a breaker. If I do this, does that in essence give each run a true 20a capacity? I know having the lights on a 20a breaker seems like overkill, but it does have one outlet on the outside of the building that I will use from time to time for power tools.....so I figured it's better safe than sorry.

Second question, should I use GFCI protection anywhere in this building?

Sorry for rambing, just want to paint a clearer pic of what I have going on. Thanks in advance for any advice.

A little confused still. Is there a subpanel? If not, then it must only have one branch circuit feeding it, which can be a multiwire branch circuit, which I think you are hinting at with the double pole breaker. There shouldn't be redundant neutrals for the MWBC between the building and your house though.

The electrical services runs directly into this panel....the house takes up approx 4 slots in this panel (these run into the subpanel inside the house). I want to hook up the small building directly to the service drop.

You will have to try harder.

Don't make us ask a thousand questions. You need to include every detail of the service panel, the building and the wiring to get proper advice.

Pictures are always a very good idea. If you can get some pictures of what you have it would help a lot!
