Maximum breaker size
required to inverter AC input
depends on model used.
MS2012-15B: 45-amp
breaker (single pole);
all other MS models:
60-amp breaker
(single pole). These breaker
sizes allow full charging and
full pass-thru capability for
your inverter model.
In mobile installations: neutral is typically not
connected to ground in main panel.
AC HOT 2 IN
(from main panel)
CAUTION: If non-breaker
units are used, a sub-panel
with overcurrent protection
is required.
