Re: Question about AC power distribution in CNC controller box

Perhaps a box within a box then? I could build a module that pokes
through the back of the main box that contains the power entry
module, relays and such. put a connector on the side of the small box
that connects to the relay controls. From the outside this would be a
single unit, but I think it would still be the same as having two
seperate modules...

What do you think?
