for power tools.

If you have extra slots in your main panel, you might want to compare the
costs of just running four individual circuits from the main panel. Four 12
gauge Romex cables would probably accomodate what you're needing.

You might pay slightly more for the cables, but you wouldn't need a
subpanel, or the extra breaker in the main panel.

Just something to consider.

Cheapest source for cable was .80/ft, but they wanted
$18 shipping! I think HD is a little over $

Copper is heavy, so it's usually cheaper to buy it locally. Home Depot has
a more limited selection, but their prices are hard to beat if they have
what you need.

Thanks for that...I could get away with running 2 circuits (#12) from the main box and that would be a solution. Is handy to have the breaker in the garage, but not necessary. Good thought!
