WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer, and lead compounds, which are known to the State of California to cause birth defects or other reproductive harm. For more information go to
www.P65Warnings.ca.gov .

Other Features:

QO 3/4–inch format: this space-saving feature saves wire.
Backed out neutral screws: save labor and installation time.
Convertible Mains: allows fast field conversion between main circuit breaker and main lugs to meet changing job requirements.
Standard 22 kA /10 kA AIR SCCR: standard short-circuit series rating for all main circuit breaker Load Centers provides increased application capability. Main circuit breaker 22 kA / Main lugs or branch circuit breakers 10–65 kA.
3–phase: QO three-phase main circuit breaker panels can be field upgraded to provide up to 100,000 A series connected short circuit current ratings (SCCR).
Interior: single, captive interior mounting screw retained by the interior. Interior mounts can be removed during rough-in for pain or theft protection.
Screws: combination slot / square-drive neutral, ground and cover screw accommodate both standard flat blade screw drivers and square-head drivers.

QO Indoor and Outdoor Load Centers

NEMA Type 1 — Indoor

NEMA 1 enclosures are typically used for protecting controls and terminations from objects and personnel. This style of enclosure, while offering a latching door, does not have a gasketed sealing surface. NEMA 1 enclosures are used in applications where sealing out dust, oil, and water is not required.

NEMA Type 3R — Rainproof

NEMA 3R enclosures are typically used in outdoor applications for wiring and junction boxes. This style of enclosure provides protection against falling rain, sleet, snow, and external ice formation. In an indoor application, they protect against dripping water. This style of enclosure does not have a gasketed sealing surface. Some models have hasps for padlocking.

Indoor Enclosures (NEMA Type 1)

	QO Plug-on Neutral QO plug-on neutral load centers offer time-savings for plug-on neutral combination arc fault (CAFI) and dual function circuit breaker installation. Our innovative, split neutrals are designed to save you time and wire, allowing plug-on neutral circuit breakers to connect directly to the neutral bar without the pigtail.
	Qwik-Grip wire management system available Save time and simplify your work by eliminating knockouts, installing wire connectors and blindly pulling wire into the load center.
	Material, Finish and Knockouts Our enclosures are from sheet steel with knockouts at top, bottom, back and sides. Finish consists of gray baked enamel electrodeposited over cleaned, phosphatized steel. Most 100–225 A indoor enclosures are 14.25 in. (362 mm) wide and 300–400 A indoor enclosures are 20 in. (508 mm) wide. QO enclosures can be rotated to allow top or bottom feed. QO load center interiors have shielded tin plated copper bus bars to ensure superior performance and durability.
	Flush and Surface Covers Indoor QO covers with latch are available in surface or flush mount and are included with our load centers or purchased separately. Doors to cover circuit breaker handles, except on 2–4, 4–8 and 6–12 circuit models. Triple lead cover screws for fast cover installation.
	Automatic Flush Adjustment QO flush covers feature a floating, spring-mounted trim providing automatic adjustment. This ensures proper alignment without manual adjustment and speeds up the final installation.
	Filler Plates Snap-in style filler plates are accessories purchased separately available to cover unused spaces. HOMFP and QOFP filler plates available for branch circuit breaker spaces in all of our covers. QOM1FP filler plates available for 100–125 A convertible load center covers. QOM2FP filler plates available for 150–225 A convertible load center covers.
	Different Colors and Styles QO covers are available in gray and white colors. Mono-Flat covers, a high-end alternative with aesthetically pleasing design and low profile surface with concealed mounting screws and door hinges are available as an alternative to our standard covers.

Outdoor Enclosures (NEMA Type 3R)

	QO Plug-on Neutral QO plug-on neutral load centers offer time-savings for plug-on neutral combination arc fault (CAFI) and dual function circuit breaker installation. Our innovative, split neutrals are designed to save you time and wire, allowing plug-on neutral circuit breakers to connect directly to the neutral bar without the pigtail.
	Material, finish and knockouts Galvannealed steel enclosure includes interior trim and door with a gray baked enamel electrodeposited over cleaned, phosphatized steel. QO load center interiors have tin plated copper bus bars.
	Stainless steel latch A stainless steel door latch on the enclosure provides closure and maximum durability.
	Wiring access without door removal Convertible main panels are side-hinge door devices, providing full wiring access without door removal.
	Bolt-on hubs NEMA Type 3R devices have provisions for interchangeable bolt-on hub. Square D type rain-tight bolted hubs provide fast and convenient top feed conduit connection. Hubs are available for 0.75 in. (19 mm) to 4 in. (102 mm) conduit size. No gasket is required with hubs from 0.75 in. (19 mm) to 2.50 in. (64 mm) when used on NEMA Type 3R load centers.
