What causes fault code GEN-PWR1 (Power Distribution Fault)?

Main breaker tripped on overload — too many loads starting simultaneously. Branch breaker tripped — single circuit fault. Utility power dip or outage — facility-wide event. Transformer overloaded — exceeding kVA rating during peak. Loose buss connection generating heat and eventually tripping

How do I fix fault code GEN-PWR1?

Check main and branch breakers in MCC/power panel — identify which tripped. Measure voltage at main buss — all phases should be within 2%. If overload trip, identify which loads were starting and stagger startup. Check transformer temperature — should not exceed nameplate temp rise. Inspect all buss connections with IR camera — look for hot spots. If utility issue, contact power company and check facility transfer switch

Power Distribution Fault

GEN-PWR1

Main or branch power distribution fault detected. One or more circuits have tripped or voltage is out of specification.

Probable Causes (ranked)

Main breaker tripped on overload — too many loads starting simultaneously
Branch breaker tripped — single circuit fault
Utility power dip or outage — facility-wide event
Transformer overloaded — exceeding kVA rating during peak
Loose buss connection generating heat and eventually tripping

Fix Steps

1 Check main and branch breakers in MCC/power panel — identify which tripped
2 Measure voltage at main buss — all phases should be within 2%
3 If overload trip, identify which loads were starting and stagger startup
4 Check transformer temperature — should not exceed nameplate temp rise
5 Inspect all buss connections with IR camera — look for hot spots
6 If utility issue, contact power company and check facility transfer switch

Field Trick

After a power event, walk the floor and count what's down. If EVERYTHING tripped, it's utility-side. If only one section, it's your internal distribution.
