Issue:
Application, Installation
Product Line:
Switchboards
Environment:
NEMA PB-2, UL 891, NFPA 70 Art. 408
Cause:
Updating an older service with a new switchboard (higher ampere rating, other necessary features) often involves feeding existing circuits from the new switchboard.
Resolution:
The current design (Series 2) I-Line distribution sections of QED switchboards lack a key feature required for mounting legacy MA, MH frame circuit breakers or electronic trip versions (MX, ME) of these legacy circuit breakers: the back pan of the Series 2 design I-Line distribution section is not punched with a cut-out for the mounting cam feature required for mounting these circuit breakers. For this reason these legacy circuit breakers cannot be installed in or relocated to a current design (Series 2) I-Line distribution section.
