| A 125 main-lug panel would be fine. Feeding it with a 60-amp double-pole breaker is also fine. Use 6/3 for the feeder.
I'd still like to know how many square feet the new panel will service. That piece of information normally goes into the calculation.
If you know anything at all about how a receptacle is going to be used, you can use that in your calculations. If you know nothing, then it is common to assume 180 watts per receptacle. |
