Load shedding can be performed in two ways. First, the PM-SC is wired to the optional trip-to-neutral load shedding function on the Generac ATS. When energized, the switch goes to the neutral position and sheds load. This feature provides an automatic reset once adequate generator power or utility power returns. The second way to perform load shedding is by taking the PM-SC or PM-IC signal to the shunt trip function of the circuit breaker for the load to be shed. This requires a manual reset that may cause inconveniences during off-hours.
