Nearly crashed my denford triac machine and not sure what went wrong, help please?

"Plugged in" or "Wired in"? And with what cable running to the shop?
If your machine can draw enough current to throw the breaker is it possible that you're getting mains voltage drop in your shop when the mill is running?
Ideally you should have a breaker on the wall which will trip before the mill can throw the supply breaker,

Hi Nick,
Thank you for your msg. What I have is a two way socket in a shed in that has a plug in circuit breaker, from there I have approximately 70 meters of 1.5mm 3 core cable to a container where I have my machine plugged in just the normal 3 pin plug. I only have one machine in the container so I am not running lathes, saws or any other machines just the mill. I used the circuit breaker in hope it would help protect my mill.
Many thanks
