Big CNC power completely gone?

@CNCtechs

Hi, I have just been carving a piece on the big CNC, and in between two programmes to run, the power has gone completely. None of the breakers have gone, but there is no lights on the board with the switches or anything.

Does anyone have any idea what may have caused this, or how to fix it? I wasn’t touching anything when it happened , neither the machine nor either of the computers - just suddenly the lights went out and everything turned off.

Sounds like there is an issue with the main breaker that feeds the whole thing…
