Please excuse my ignorance. I'm a bit new at this. I have only done one panel upgrade and the house had like 3 circuits in it. It was pretty easy. If I'm upgrading a panel with multiple circuits (100 to 200 amp) what's the process? Is it as simple as having utility disconnect in morning, install new panel, connect existing ckts to new panel. Or take ckts back and splice in a junction box? I guess each circumstance is different. Also, where does the inspection take place if you are disconnecting reconnecting the same day?
