I have 8 large tools on one 20 amp circuit and never once had a
problem.Â*Â* Air compressor, Dust collection and Planer are on separate
circuits. Planer is 240 otherwise it would be 9th on my list.
Naturally this would not be cool in a multi-user commercial shop.

Surely all (or almost all) of those "large tools" are dual-voltage
motors.Â* Why wouldn't you switch them all over to 240V?

Most of my stationary tools have been running perfectly fine for almost
70 years.Â* Most of them are 1 hp or less, so no, they don't all have
that option. Table saw does have the option and I'd thought about
changing over to 240 many times but just never got around toit. Probably
because the reward/effort didn't motivate me enough.

My key item for stationary tools is they all be on magnetic starters so
won't restart if for any reason there is a power interruption.

When I bought my used shaper, it had those big red/green buttons that
looked like those on the magnetic switches.Â* I assumed it was a magnetic
switch. One day I lost power and when it came back on, so did the
shaper. That was the only time in my lifetime that happened to me, and
it wouldn't have happened then if I knew the switch was not a mag
switch. My newest tool is my planer, and it came with a mag switch,
otherwise, I'm on my own to switch off power to all my tools.

So far, other than that one event, I'm doing ok.Â* I'd say it's a good
idea, but not a "key" item, at least not for me.Â* If it was, I'da
"switched" all the switches long ago:-)

OK, so they aren't all that big, after all... For 1 hp I'd agree
it's pretty-much a wash. Only the little light duty shaper and the old
10" bandsaw are, here, so more incentive.

The example w/ the shaper is why I don't let anything past the gateway
-- if that were quick and you didn't react in time, there's not a much
more dangerous tool in the shop than a shaper.

I was fortunate in "glomming on" to a supply of the old Rockwell
starters used in a large woodworking manufacturing facility in PA (they
had 27 of the old Rockwell/Delta Model 13 planers arranged in 9 rows of
three set a fixed thicknesses the did rough prep on all the flat stock
coming into the plant. When they upgraded, they sold the lot either
intact or piecemeal for some of the more badly worn out ones.
Consequently I had a ready supply to retrofit with).
