We recently moved into a older home and there is a garage detached from the house about 100 feet from main breaker box. There is a electrical panel under the meter (outside of home) with a 60 amp breaker that feeds the garage. I was wondering if anyone knew how to identify the electrical wire running from 60 amp breaker to sub panel in barn/garage?
I want to upgrade to 100 amps and thought there might be a chance that the wire already ran the 100 feet would be rated for the boost in amperage. Also, what wire would be ideal, copper and aluminum, for running new 100 amp service line 100 feet to detached barn/garage?
Thanks, Josh A.
