I recently added some new, heavier-duty equipment to my garage
woodshop and am now finding that I'm tripping the breakers more often.
There are two circuits in the garage, both 15 amps. The new tools are
rated as high as 20 amps and trip the breakers under loads (no
surprise there). If I upgrade, should I just take these circuits on up
to 30 amps? Is this as simple as merely installing new breakers, or
will it likely require some rewiring? I don't plan on trying to do
this myself, but I would like to get a feel for what's involved and
how much it might cost. The house was built in 1978. I'll be calling
the electricians this week in any case.

Thanks.

If you have 15A circuits now, its likely you only have 14 gauge on
those 2 circuits. You have to re wire with 12 guage wire , and then
you can change out the breakers to 20A. Or you can just leave those 2
circuits alone and run a new 20A circuit. 30A is not really practical
for this application.
How far away is the panel? If its close, and if you can run new wire
to it with no problems, its fairly easy and straightfoward for an
average homeowner to do themselves.
