I am trying to run a wire from a breaker box to a new plug. To get to the new plug, I have to run the wire over a garage with a finished ceiling, around, through, or over 2 half staircases ( bi level) to get to the unfinished wall to run to the new plug. What would be the proper way to run this wire.
That depends on your local and state codes and the conditions. Exposed? Concealed? All dry locations? Distance? I'd have to know way more to give you an accurate answer. Call an electrician to advise you.
YOU CAN USE 100 AMP WIRE ONLY IF IT HAS A BREAKER AT THE POLE BOX FOR 100 AMPS
Unless you are really small and can climb through all those small places in the attic...you are going to have to try another way. Most of the time those wires are run through a conduit on the outside of house. up under the roof line edge.
If you don't need a dedicated line, just tap it off the closest outlet to the new location. Otherwise,can you run it thru the garage attic and down the wall into a crawl space? You may have to surface mount it along house, or use buried cable outside. Without seeing it, it is hard to say. I'm an electrician and we have had to run things all kinds of ways.
You could also run the wire in wire mold which could be surface mounted to your ceiling in the garage and up walls in your stairway. Basically any place you would have bare romex showing it would covered by the wire mold. Easy alternative to fishing wires if you don't mind the look of wire chases on your wall. Personally, i would fish them where ever you can. It's almost always a better job. Check with your local electrical supply store. You may find a decorative mold you can live with. Good luck.
