save money. If you have to put the panel inside, you need to
runa service entrance cable from the meter base to it.
That’s a lot of work and it’s expensive stuff.
if you put the panel next to the meter base with a piece of EMT
between it, you can use #2 wire.
Also, many jurisdictions now require an external service disconnect for the
fire department and the power company, so, if you put the main panel
out there, it covers both.
