Product Line:
QO singe phase load centers
Resolution:
The QO, single phase, main lug load centers are SQUARE D CERTIFIED for use on 125 VDC systems. The load centers listed ARE NOT MARKED for use on this voltage system, however are suitable for the application. The positive (+) conductor should be connected to one phase lug, while the negative (-) conductor should be connected to the other phase lug. USE QO, 2p BRANCH BREAKERS ONLY. QO branch breakers, 10 - 70 ampere, are also SQUARE D CERTIFIED for use on 125 Vdc systems. Short circuit current rating is limited to 4 kAIC (10 - 30 A) or 10 kAIC (35 - 70 A) when used on 125 Vdc.
