I currently have an underground service entrance that comes in on a side garage wall. I’m planning a third stall addition to the garage that will attach to this wall and hence I need to move the service entrance. I’ve talked with the elec. company about installation of an armored entrance cable while the third stall is being built so that we can work around the energized feed safely. No problems there. Question is, what are my options for the distribution panel on the new service entrance that would be located on the wall of the newly constructed third stall. I would like to maintain the current distribution box as is – it has about 28 circuits running to it.
Can I simply use a new main panel at the new service entrance and use the existing box as a sub panel? Or are there some other ways to do this. Current box is 150A and I would like to have another 50A to use in the new stall of the garage as this will be a workshop.
BTW I will have an electrician install the new box and wiring.
Thanks, Chris

Yes you can have it done. Specify a 200 amp main panel and service entrance. Use a 150 amp breaker in the new panel to feed the old panel. 4 conductors are needed between the new and old panel as now the neutral and grounding conductors will be separate items. In the old panel, the electrician will isolate the neutral buss and conductors from the grounding buss and conductors.
Your new circuits can be wired into the new panel. You will have enough amps for welder, compressor, saws, etc.
