Issue:
Product design features

Product Line:
QO singe phase load centers

Environment:
Voltage ratings

Cause:
Application

Resolution:
The load center catalog numbers listed below are SQUARE D CERTIFIED for use on 125 V dc 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 2-POLE BRANCH BREAKERS ONLY. QO branch breakers, 10-70 ampere, are also SQUARE D CERTIFIED for use on 125V dc systems. Short circuit current rating is limited to 4,000 amperes (10-30 ampere) or 10,000 amperes (35-70 ampere) when used on 125V dc.
