What enclosure can be used for a QO120GFI circuit breaker?
QO Load centers and Circuit breaker enclosures
Square D does not offer an individual mount enclosure for a single pole, 120Vac only, QO-GFI circuit breaker. Recommend using a small Main Lugs Only load center for this application. Consider using a QO24L70F or QO24L70S for an indoor, NEMA 1 application or a QO24L70RB for an outdoor, NEMA 3R application. A maximum #10 AWG branch conductor can be used in the recommended application.
