or two.
Does it make sense to run a 60 amp subpanel off of a 100 main panel? Something in my EE head says that's a bit goofy and pushing the limits of the breaker and panel. The main is full but includes two circuits for the 120V air compressor, 220V bandsaw/jointer which would move to the sub panel.
Is a 60A subpanel and breaker sufficient to run a 220V 20A circuit for the DC, a 220V 20A circuit for the bandsaw/jointer, 120V 20A for the air compressor, and 120V 20A for the TS/Router/tools/etc? By my math that's a nicely balanced load of 60 amps on each leg but also at the breakers maximum.
Lastly, a recent panel upgrade post got me thinking of an idea of handling the frist question if I have to upgrade to a 200A service. Could I install a small 200A panel next to my current 100A panel, and power the 100A from the 200A and effectively turn the present panel into a subpanel?
