3-phase 120-208v 60 amp branch circuit for a commercial dishwasher.
Panel is a Sq D QO.
Sq D does not offer this breaker.
Am I correct under the 2020 NEC that it must have GFCI protection? 422.5(A)(7)

What is your suggestion for a solution?
 
After I made this post, I see a thread that was started for a similar problem. Has a better solution than the Bender Lifeguard line been found?
 
Is the panel actually a QO? (Loadcenter) Or is it a QOD panelboard? The QOD will take plug on or bolt on breakers. Then again, don’t know if they make that breaker in a QOB either?
I’ll lay my own eyes on it tomorrow, but my electrician on site said it would not accept QOB breakers. I thought this as strange too, since it’s a 3 phase panel. I believe a 3 pole 60 QOB is readily available.
 
Yes sir. Just the fact that this is a relatively new convince store, and built in affiliation with Shell, my gut is thinking QOB. But, I’ve been wrong plenty times before. I’ll know by 8:00 am tomorrow. In the absence of any better suggestions, I’ll find a small 100amp MLO panel and go that way.



I ran into a situation yesterday that you guys can appreciate. We answered a residential service call for a report of partial power. We found an antiquated meter base with breakers built in. Failed breaker. I’ve seen these before, but I didn’t have one in my pile of junk. It was a Murray, SP 20amp bolt in. It had a model number on it that said 1803 if I recall correctly. Of course everything about the service was 50 years beyond needing to be replaced. And the resident obviously doesn’t have a dime to spare.

We found the breaker at a local liquidator for just under $200. Replacing the breaker would be like putting a band aide on cancer. We will do the right thing and replace the service for next to nothing. We would do it for free, but you could tell their pride would be hurt. We will charge them a little bit and then accidentally leave a gift card behind to a local grocery store.

Could be a loadcenter then, Dollar General does that on their stores. They build them cheap as possible, and gas stations are no exception.

North GA Hillbilly, our daughter is a South GA swamp rat. Waycross. Heat, humidity, alligators, mosquitoes, fire ants, 3” long roaches, snakes, and scorpions. And she wonders why we never visit?
