The wife wants the clean look of an electric range so I guess I'm not

going to have to run a 220v 50A circuit for the range, but also install

service

box.

My first inclination is to install a 60A sub panel because I will of

course

be installing at least one 50A circuit. Yet, a 60A panel with one 50A

seems

like I'm cutting it close.

Also my intension was to use 6/3 for the range circuit (about 25 feet

long),

what should I use to run to the sub panel. The run won't be more than 2

feet

(I'll be mounting the sub panel about 8 inches from the main and

connecting

them with EMT). I would think it would also be 6/3 because that's rated

for

65A.


How about a 100A subpanel? You may need a feed-through lug kit for your
old box, but they should be cheap. Use four #4 wires, although the
ground and probably the neutral could be #6.

I would look into replacing the main panel with a 150A and not need a
subpanel, but adding a subpanel might be adequate and would be a lot
cheaper. You need to do a load analysis and see how much headroom your
existing service has.

Like you said, cost. Headroom should be fine. There was an electric range in
the kitchen before remodeling back when I had a 60 amp service with no main
breakers. I really don't think I'll need another 100A box. Another 8
circuits will probably last me.




I meant another 100A box fed as a subpanel off the first box; it would
give you 6 to 12 additional spaces, but no added capacity because it
would be limited by the 100A main breaker in your main panel.

100A and 125A "main lug" load centers are *really* cheap. There's no
reason you can't feed one from a 60A or 70A breaker in the first panel,
or from the feed-thru lugs, and it would give you more spaces than a 60A
subpanel.
