TS and shopvac electrical question

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
proceed.

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.

Regards,

Thanks for the posts with feedback. I think I will see if the wiring is ok
to use a 20A breaker and see if that helps. Just fyi, the problem was more
tripping the breaker when the saw was under heavy load rather than just at
startup.

If you take a look at the link below, you will see where I got the idea. I
found the plug at Sears, called a."Sears Automatic Power Switch. I found it
in the hardware dept for 19.99. The Sears sku number on the receipt is
24031.

Slow blow breakers?! Maybe you are thinking of fuses?

That's a breaker marked "HACR", suitable for starting an A/C. They may be hard
to find in single pole.

You need all or some of your shop circuits wired with #12 wire wirh 20 amp
breakers. That would probably be enough to keep from tripping breakers.

Change your circuit breaker out to the EXACT SAME AMPERAGE RATING except get
the Slow Blow Style. As you indicated, it is the start up load that is the
problem. The Slow to Trip breaker will give the tools a second or two
longer while their load on the circuit lessens.
