Hello there.
I bought a pair of Porter Cable 75182 routers from ebay a while ago for my cnc machine, they are rated at 15 amps at 120V so 1800W, ive got one mounted on my machine and it seemed to run fine for 3-4 small jobs then just stopped working.
It was run via a relay in my control box that provides 230v to a 110v site transformer that is then connected directly to the router. The site transformer says 3300VA on it but it turns out its only rated for 1/4 duty cycle, not for continuos use. Its now short circuit so that site transformer is dead, it didnt get hot from what i noticed, and the current breaker did not pop out, im now left wondering if this is a bad idea and i should just abandon the porter cable and go back to my old router. Is it just that it drew too much current and if i get a larger site transformer it will be fine? Or am i missing something? I cant really see why the breaker did not go...
Many thanks
James
