14 Top What Size Electrical Wire, 100, Service Images - Now i additionally am looking at the neutral bar and that i see as a minimum 6 neutral wires on small branch circuits where the cord is aluminum. Now aluminum is first-class for the huge feeders like your supply cable, due to the fact the ones have a tendency to be established with care. However for 15-20-30a department circuits, aluminum calls for very specific technique and properly rated terminations - and within the nineteen sixties-80s, it did not get it. Installers labored rapidly and shabbily, and the enterprise didn't recognize about accurate torque, no-ox compound, alumiconn splices, or co-alr terminations as they do now.

On the grounds that there's most effective a single available slot (three), it's now not probably a primary a/c system can be related without moving matters around (no less than). Upgrading the panel might be your handiest alternative, but it might rely on the existence (or lack thereof) of a sub panel, and the existing provider provided to the constructing (and availability of services within the region). The panel is rated to aid 125 amperes, whilst related to a one hundred twenty/240 volt three cord system. Which means one hundred twenty five amperes can waft via each of the top bus bars and each fundamental lug, without whatever melting or catching hearth.
So now i am thinking, thinking about how terrible the quote became from the primary seek advice from, possibly he became simply trying to squeeze even more money out of me? Why did my inspector tell me it became a 70 amp panel?. The circuit breaker is rated at a hundred twenty five a, in line with its label. It's far a "cut up-bus" panel. It's miles currently configured to have three "principal" breakers (that is, you have to turn three things to show off your strength) which can be wired in parallel. Counting the used power is a bit bit complex because you must carry out the count for every leg individually: you can have up to one hundred twenty five a on l1 and every other 125 a on l2. I be counted a hundred thirty a on every: 50a 50a 30 a double pole breakers.
