QO 3-phase load centers
Resolution:
TOP FEEDING:
ALL of these load centers come with the main breaker or main lugs located at the top of the load center interior and can be top fed as standard.
BOTTOM FEEDING:
NOTE: BOTTOM FEEDING OF THESE LOAD CENTERS WILL BE COMPLETELY DEPENDENT ON LOCAL CODE AUTHORITY ACCEPTANCE.
1) For main breaker load centers:
The QO324MB100 uses a backfed branch breaker as the main breaker, so bottom feeding it would require the COMPLETE load center and cover to be rotated 180 degrees, so the mains is located at the bottom. This will not cause the labeling to be upside down, it will just start the circuit counting on the directory label at the bottom of the cover where the main lugs are located, but it will read appropriately.
The QO342MQB200 uses a standard Q frame main breaker located at the top of the interior and contains the CSA required mains service barrier, so bottom feeding it would require the COMPLETE load center and cover to be rotated 180 degrees, so the mains is located at the bottom. This will not cause the labeling to be upside down, it will just start the circuit counting on the directory label at the bottom of the cover where the main breaker is located, but it will read appropriately.
2) For main lug load centers:
All of the Canadian, QO, 3 phase, NEMA 1, main lug load centers come with the main lugs located at the top of the load center interior and can be bottom fed by rotating the complete load center and cover together 180 degrees so the main lugs are located at the bottom. This will not cause the labeling to be upside down, it will just start the circuit counting on the directory label at the bottom of the cover where the main lugs are located, but it will read appropriately.
