B-LINE 1MMBC1 – Frequently Asked Questions
1) What does the B-Line 1MMBC1 tenant breaker cover actually do on a meter stack?
The 1MMBC1 is a hinged cover for the tenant breaker position on a residential meter pack or meter stack. It's the door over the breaker, not the breaker or the meter socket itself, so it does not add or change any overcurrent device. It swings on a hinge, so a property manager or electrician can get at the tenant's main without pulling the whole deadfront off.
2) I need to replace a broken breaker door on an Eaton meter stack in a multi-family building. Is this the right part?
If the stack is a 125A residential meter pack or meter stack and the piece you're replacing is the hinged tenant breaker cover, the B-Line 1MMBC1 is that part. It's a cover only, so it does not include the breaker, the meter socket, or the deadfront behind it. For a fleet of units, order by the model number 1MMBC1 so every opening gets the same door.
3) Does the 1MMBC1 come in more than one size or configuration?
One configuration only. The tenant breaker hinged cover is sold as model 1MMBC1, with no size, finish, or amperage options to pick from, so there is nothing to specify beyond the part number.
