Hi,

I have a subpanel that is in a very convenient space and it is so very
temping to put a lot of stuff on it (kitchen /includes 30amp stove +
garage + central A/C + etc), but my electrician told me that it's not
proper to draw more than half the amperage from the main panel. Is that so
and what's the rational for it.

The sub-panel is 18ft away from the main panel and is fed by a 2-2-2-2
wire. I found this table

WG gaug Maxamps for chassis Maximum amps for power transmission
2 181 94

which I guess is saying that the max amps is 94, but I'm hoping that
that's a rating for 100ft and I can go to about 125 over 18ft.

So I guess there are two questions in one:
1. Can I draw 125 amps on the basis that it's more that 1/2 the total
service (200amps)?
2. Can I draw 125 amps on the basis that it's 2-gauge wire?

Thanks

Aaron

I would recommend running your heavy loads off of the main panel, simply to
prevent lights dimming due to the smaller feeder (#2 vs. 4/0)

If this is an existing sub panel, it will have a main breaker in the service
panel, which will limit the current that can be pulled from it, which I
can't determine, not knowing if it's feeder is aluminum or copper


The subpanel is fed by 2-2-2-2 copper.
