Today, the maintenance chief at one of them wanted a power kiosk in one of the parks converted to ground-fault outlets so that the permitted users wouldn't be constantly tripping the breaker by overloading the one GFI they had available. There was a small panel on the kiosk that fed two split-wired receptacles, which weren't GFI protected.

Since the existing receptacles are standard type, while GFIs are rectangular, it seemed that using a mill to cut the plates was a good idea. It was an easy step to use the CNC mill for the job. Here's the pair of plates as removed from the panel, along with one of the GFI outlets to be mounted in it.


It didn't take too long to work up the drawing and convert it to G-code for the two rectangular cut-outs in each plate. Fairly easy to clamp it to the table over a piece of sacrificial wood and set up the 0,0 point.


A bit of cleaning up with a file, plus a pair of mounting holes for each receptacle, and the job is done. I'll be back in that town on Friday and will install them then.

Very nice Hawkeye. Those CNC machines are cool. I don't know if I could learn to operate one but they sure are fun to watch.
