I am the happy new owner of my first table saw. My garage shop has two 15
amp circuits installed for outlets. I normally run my router on one circuit
and the shop vac on another. I can now do the same with the table saw, no
problem (so far).
The thing is, I got a nice new thingamajig with kind of a slave circuit on
it. You plug the box into the wall and then plug the table saw (or router,
but it only supports one device) into the main outlet. When you turn on the
main device, whatever is plugged into the second "slave" port turns on also.
I have my shop vac connected to the slave port and it is totally cool to
just flip the TS switch (or router) and have the vac crank up. I know the
startup load of both motors cranking up is a lot for one circuit, and I have
already tripped the breaker twice in one day ripping a 2x4.
I want some advice from those with some electrical knowledge as to how to
I can always use the two outlets on separate circuits, but would really like
to keep using the master/slave box I just purchased. What would the best
type of circuit be to fully support both the TS and shop vac in this way? I
am willing to get an electrician to do the work (and maybe put in a 220v
circuit for future use), but for now I have a 110v table saw and router so
would like to have one single circuit capable of running either one of these
devices simultaneously along with the shopvac.
