460V MCC

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Do they still call them ‘buckets’?

It depends. Yes some MCC's are bucket like. But true breaker buckets you rack in and out go to 2,300 Volt transformer rooms.

Rule of death avoidance..........Never rack a bucket in or out under a load. Daily rule of death avoidance............Never pull fuses under a load from a 460V MCC. Last updated and revised death avoidance rule.........Never be in such a rush that you connect a VFD load line to the DC braking terminal screw.

Not to reveal all my mistakes in the past decade........

Never slug a motor starter contactor before verifying there is no potential L1,2,3, to ground, or short between L1,2,3.

And never dismiss asking questions when someone comes and asks you for a fish tape. I had an electrician ask me for a fish tape? I gave him a Greenly 50' tape. He then went and fished a wire inside the back of an energized 2,300 Volt distribution panel to an available bucket slot. Unfortunately he didn't explain what he wanted it for? The steel tape crossed phases and there were just shoe prints left in white around a soot scorched concrete floor.

For that you need a fiberglass tape and a damned good reason to be working 2,300 live. You also need to be in your space suit. Gloves and a face shield just won't save you.
