Walked into a plant this afternoon, to quote some work, and I am still noticing guys installing CNC machines, lathes, and such with ground rods by the machines.
I know manufacturers "require" this but the NEC is still somewhat unclear.
Under some excemptions you can put a ground rod if you want but the EGC from the feeder must be tied to it. You can't connect the ground rod by itself to the equipment without that being tied to the service ground.
See where i am going, I hope...
I remove them when I find them, after checking that an EGC was installed.
Am I on the right track?
Dnk.....
