Hi. Ick Christopherson here. [scared] (Shane, don't even try to tell me that wasn't a Freudian slip....hehehehe).
The amp draw of the router will depend on how much you are loading it. (i.e. how big of a bit and how deep of a cut.) Under a full load, yes, it will draw the full 2200 watts (18 amps). However, this is only under full rated load, which is not very common. The smaller the bit or shallower of cut, the less the load. You can operate this router from a 15 amp circuit if you need to, but you may be limited to the amount of load the router can take before it trips your circuit breaker (but still very close to the full load). It won't damage the tool, and your circuit breaker will still protect the circuit as it is designed to.
Yes, this router can be used with a CT vac with the same caveats. The total power drawn by the router and the vac can exceed the capacity of the circuit (even a 20 amp circuit), but the breaker will trip to protect the circuit. The CT vac can sustain the full power of the router.
The bottom line is that your circuit breakers are the limiting factor, and they are there to do just that very thing.
