how do you test for an open

Can I test for an open wire? How can I find out which C/B powers this circuit?

To find an open connection you need to examine each and every receptacle on the circuit. The open will be at or between the last one that works and the first one that doesn't. If you don't know the routing of the wires you will have to check every junction box (receptacle, switch, lights, whatever).

You should already know what circuit breaker powers this circuit. if you don;t then shame on you. EVERYONE should completely map out there entire electrical system shortly after moving into a new house or apartment. Your goal is to know which circuit breaker controls each and every receptacle, light and appliance.

Knowing this information helps when you have a problem (like now), but more importantly, it could save your life some day.

If you really don't know what is on each circuit breaker then you will have to make educated guesses.

I went one step further in my first house, in that on the inside of every cover plate, I marked the circuit breaker number that controlled the outlet. That way, if I ever had a problem, I could go directly to the proper breaker and check it out. That was in addition to making a comprehensive list and tape it inside the panel door. The original sticker looked like a cross word puzzle by the time I moved in (a puzzle done in ink).

This isn't my house. I know how I would mark everything for me. How would I do it for someone else? Use official symbols or just list them like kitchen light and back bedroom outlet?

Depends on why you're doing it, and how good of a job you want to do. If it's not your house and you don't care much, then any old crappy job will do. Just shut off each breaker, find one thing dead, and write what room it's in next to the breaker. Get in and out fast.

On the other hand, if you want to do a good job, plan to take several hours. And you won't be able to fit all the information on that little form on the inside of the panel door.
