Extension cords are not to be used "in place of fixed wiring"- so unless
it's a portable saw temporarily set up, it's a code violation. Using a home
made extension cord to connect the 220V receptacle by the TS to the
receptacle on the wall would also be a violation.
That's very dangerous... but if you must use a switch, use a good pull-arm knife
switch type in a box, not just some
cheap crap wall switch. Crap breaks... you want a positive break in the circuit, not
a toggle spring waiting to zap
you!! And wire the lights on another breaker!
I put an outlet over my saw, its cheap and with my poor memory, saves body parts...
The worst feeling you can have is finding current in a machine you were sure was
dead!! Oops is not a good word when you
PS There has been a ton of electrical questions here, for the record - its 120/240
volts... all those 110, 115, 117,
220, 230 references are out of date.
also, 208 refers to 3 phase industrial power, home current is single phase, center
tapped 240. (120+120)
I have what you want right here on the table next to my computer.
It's a "Square D Pull-Out Disconnect Switch". The one that I have
is 30 amp fusible model FP221R, but you can get them without fuses.
There's a small bar with a pull tab on it inside an electrical box.
Put the bar in one way and there's no electrical contact. Put it in
the other way and you're good to go. Put the bar in your pocket and
nobody can turn it on while you're working... You can also lock the
This is usually used as an outdoor air conditioning disconnect. I plan
to use this one on a jointer with a five horse motor on it ( 240V@27A ).
That is the correct answer! Combines the comvenience of a switch with the
safety of true current interruption! Switches can fail in such a way that
they pass current unexpectedly, but this unit is fail safe. I would still
remove the bar when changing blades. I think we humans need a strong visual
key (like the plug laying on the floor, or the bar sitting on the work
surface) to reinforce our safety habits over the many hours in the company
of tools that can hurt us. All it takes is one mistake...
