Breaker Transfer Pairs in lieu of an ATS

[Mort J]

I have cabinet depth restrictions and need to quote an ATS style breaker transfer pair with automated controls.

I'm wondering if anyone knows what accessories would be required on the breakers? I'm assuming they'll have to be electrically operated. Would long time, short time, and instantaneous electronic trip settings be accurate? Would I need ground fault trip on the breakers or is that unwise? Having trouble finding information on code requirements or industry standards.

This is to be labeled UL891, so UL1008 does not apply (though I believe we'd be building to that standard regardless)

Any help would be much appreciated.

Contact manufactures Eaton will make you what you want in a CB transfer, or they will furnish switches.

Yes, Eaton lists as a catalog item a dual breaker based, electronic relay controlled assembly as ATS.

Ul1008

Ul1008

Offered as a UL1008 or UL891 if you want distribution included.

3-pole & 4-pole breakers available.

If footprint is a real kicker you may want to also look at Russelectric, they may be able to offer a more compact unit as they typically provide gear that is very custom in application adn have any number of variations.

I will go with an Eaton Breaker-Breaker type with an IQ-transfer

Not sure why UL1008 would not apply to anything labels as an "ATS", but if that is all there is to it, you might try this outfit. They make listed ATS systems using breakers.
