2) Part number PKSB1HA is the Service Barrier kit for ALL the Convertible load centers that use the QOM2 Main Breaker. 
3) Part number PKSB1QOBF is the Service Barrier kit for ALL the QO612, QO816 and QO148... load centers that would use a Back-Fed branch breaker for the Main Breaker. 
4) Part number PKSB1HOMBF is the Service Barrier kit for ALL the HOM612 and HOM48.. load centers that would use a Back-Fed branch breaker for the Main Breaker.

NOTE: This UL and NEC change became a requirement as of Jan. 1, 2017 and all of the Convertible Main Breaker load centers shipped from the factory will include the Service Barrier kit. But for all Convertible Main Lug load centers, and any Back-Fed applications, the service barrier kit MUST be purchased separately. Also, for all load centers that already exist in the field, either Distributors Stock or Retail stock OR for customers who want to Back-Feed branch breakers as a main, the kits MUST be purchased separately.
