Issue:
An HOMT Homeline tandem breaker will not install into a Homeline load center.
Product Lines:
Products sold in North America
Environment:
Homeline Tandem Breakers (HOMT), Homeline Load Center
Resolution:
NOTE: Catalog numbers starting with 'HOMC....' are not load center part numbers. These are load center cover part numbers.
Older style or Non Plug-On Neutral Homeline load centers were designed to meet the UL standard and the NEC Circuit Limiting Requirement(42 circuit rule). Because of the circuit limiting requirement, not all spaces in the older Non Plug-On Neutral load centers would accept tandem breakers.
NOTE: If the load center is not designed to accept HOMT tandem breakers, then the HOMT's CANNOT be installed in the load center, it would require a newer load center that is designed to accept tandem breakers.
The HOMT tandem breaker, example HOMT2020, has a rejection feature built into the breaker casing. The rejection feature is a ‘Short Notch’ in the breaker casing, where the breaker plugs onto the bus stab of the load center. This short notch prevents the HOMT from fully engaging the bus stab and therefore will prevent the deadfront/cover from fully seating over the branch breakers. Only certain Homeline load center catalog numbers that were designed to accept tandem breakers will allow the tandem to be installed.
