Issue:
Application of Micrologic ground-fault capable main breaker in a NEMA 3R I-line panel
Product Line:
I-Line Panelboard
Environment:
I-line panelboards in NEMA 3R enclosures with ground-fault main breakers
Cause:
Product selector will not allow selection of LSIG main breaker for I-line panelboard in NEMA 3R enclosure
Resolution:
No. Ground fault capable LSIG main breakers for I-Line panels are NOT available in NEMA 3R enclosures. The GF feature requires a box extension for the Neutral CT assembly and NEMA 3R boxes cannot be extended. Possible solutions are to switch to a NEMA 1 application or to use a remote main breaker in a separate enclosure with a Micrologic LSIG trip unit.
