Sub panel size, if I'm wiring a 50A range circuit to it?
 

The wife wants the clean look of an electric range so I guess I'm not only
going to have to run a 220v 50A circuit for the range, but also install a
sub-panel because I was down to 2 open circuits in my present 100A 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.

Why don't you just put in a 200 amp service and get rid of the outdated 100
amp box?

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.

Run a 60 amp sub-panel and transfer enough circuits into it to allow the
breaker for the range to be installed in the main panel box. If you use a
large enough sub-panel, you can make enough room for the sub-panel's 60 amp
breaker plus the 50 amp breaker for the stove in the main panel then use the
sub-panel for lower amp circuits plus have extra positions left for any
future additional breakers.

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.
