Crappy gear design

[chris kennedy]

Anyone know if the lugs and bus fingers on this breaker can be reversed? Line side of breaker is attached to bus so POCO would have to be landed on bus leaving bus energized with breaker open or closed.

Thanks

MLO panel / switchgear with plans on using up to six mains in the future?

That is what it seems like to me.

That appears correct but the contractor is interested in making the 1200 the main.

Land the service conductors on the bus and the 1,200 is the main. Perfectly NEC compliant and leaves the option of adding five more 'mains'.


I really don't know if it can be reversed, likely it can be but that is not a modification I would contemplate in the field without written directions to do so from the gear maker.

Contractor is going to call gear supplier tomorrow to see if it can be reversed. Also mentioned that the intent was to add a future additional 600A for another MRI. Issue is that would require a POCO shut down to accomplish.

Sounds like a solid plan.

Yes or add the breaker today.


I see this type of installation done often to avoid expensive GFP mains.

That breaker has "LOAD /CARGA" written at the bottom, that could rule backfeeding out.
