I have a 1985 Chucker. With the spindle running at lower speeds everything is ok, after a minute or so with the speed 2500 or above the lathe will power off. This is with no load/cutting.
There are 9 breakers/heaters at the lower part of the machine. The three center ones labeled C0.87A can be reset after a little while and everything is normal again. This is a new machine to me, and I am not an electrician, so I am guessing at what the issue may be.
Looking at other threads people have said it was the heater.

I am using a RPH so the power should be clean.
The white on L3 is my generated leg.

Could something else cause them to trip?
Thanks in advance!!!
