I'm sure that the specs indicate that a larger circuit would be appropriate for this configuration, but in the real world, particularly on a job site, normally you would on have a 15 amp circuit.

I am not on the jobsite, but in my world's smallest work closet, would a kapex plugged into a CT 26 and then into the wall, if they run without blowing the breaker, am I OK or do I risk damaging the motors, etc.? If they run, will they only run half speed if the power is insufficient? This is my first kapex and I am used to the scream of a typical miter saw, the kapex is much quieter and I am concerned that I am running at something less that top speed.

According to a call with my electrician, he says that the motors will pull full power through the circuit and if they don't trip the breaker I should be good to do, so long as we make sure that the breaker has not gone bad.

What say you? Absolutely must upgrade the wiring and circuit to a 20 amp or 30 amp circuit, or if it works, run it normally if it is not tripping the breaker. I cut some 8 quarter hard wood and it seemed to run OK, but the motor sound seems off to me, will go to the store and listen to theirs, I suppose.

Thanks for your help. If there is a thread on this topic that I missed, please let me know.

One last thing - I wasn't aware of all of the history and discussion of motor problems with the Kapex - have the prior issues been resolved with the current version being sold?
 
Yes, there've been discussions on the points you raised in this forum and the conclusions have always been that using the Kapex with the CT26 on a 15 amp outlet is absolutely fine.

And there have not been any "smoking" motor issues reported on the REB model.
