PCS SETTINGS
REMEMBER YOU SELECTED PCS AS YOUR TIE-IN METHOD IN BUSBAR 1 AKA THE MSP
Here we have set the PCS to comply with the limits of the 120% rule for a 200 amp bus with a 200 amp OCPD
200 * 1.2 = 240 - the main breaker rating = 40 AMPS OF AVAILABLE BACKFEED.
Set your PCS settings to 160 amps to keep the export within the 120% Rule
