Issue:
On panelboard interiors NF430M1 or NF430M1C using a 125A main breaker, can the panels be converted to a shunt trip type main?

Product Line:
Panelboards.

Environment:
Products sold in the United States.

Cause:
Product features.

Resolution:
These panels cannot be converted to shunt trip main, because of the extra pole space that the main breaker`s shunt trip takes up. An option might be to backfeed a Main Lug Only panel with a shunt tripped EDB breaker, which would take up 4 available pole spaces.
