Ring or ringless styles available
Available in two styles for either QO or Homeline circuit breaker formats
100 to 400 A main ratings
Units available with up to six service disconnects (For NEC^® prior to 2020)
Available plug-on neutral option (PoN)*
Dedicated surface and semi-flush mounting styles
Multiple disconnect units can be converted to semi-flush with addition of flange kit
Generator Kits available to provide switching method between main utility service and backup power source
NEC 2020 for most models
Solar ready available option
Some models are Wiser™ Energy compatible
Backup power ready available option

The Plug-on Neutral (PoN) Advantage:

Faster installation — Fewer connections
Saves wire — Fully distributed split neutral bar
Frees gutter space — No pigtails

Meter Main Product Description

Used in residential applications where local codes require service disconnects to be located outside the dwelling.

Meter main devices include the utility meter socket and factory installed and/or provisions for field installation of service disconnect(s) to feed downstream devices. Meter mains are typically used with interior mounted sub-feed load centers.

Additional features:

Circuit breaker compatibility – QO is a 3/4-inch format and Homeline is a 1-inch format. Some interiors (solar ready) accept plug–on neutral (PoN) and pigtail style branch circuit breakers.

Backed out neutral screws – saves labor and installation time.

Standard 22 kA / 10 kA AIR SCCR — standard short-circuit rating for most combination service entrance devices (CSEDs) provide increased application capability. (Some CSEDs have a different SCCR, see product Technical Information to confirm.)

Neutral and ground – supplied with 100% branch neutrals; all unused terminals may be used for equipment grounding wires.

Twistouts – twistouts are factory removed in some models for easier installations of circuit breakers.

Screws – combination slot/square drive neutral, ground and cover screw accommodate both standard flat blade screwdrivers and square head drivers.

UL listed – suitable only for use as service equipment.

Type

CSEDs for use on electrical systems are UL™ listed under file E-6294 (panel boards) and meet federal specifications W-P-115c, type 1, class 2 for use in government housing.

UL Listed

File E-6294 (panelboards) UL67 standard enhances safety in electrical distribution panels. Suitable for use as service equipment. Suitable for use with 75°C copper or aluminum conductors.

Ratings

Single-Phase, Rating Max: 100–400 A

Service

120 / 240 Vac, 1φ3W

208Y / 120 Vac, 1φ3W

Neutral Assemblies

Branch neutral terminals suitable for one #14–#4 AWG copper or one #12–#4 AWG aluminum wire.

Suitable lugs provided on the neutrals for termination of the grounding conductor.

All unused neutral terminals may be used to terminate bare or green equipment grounding conductors:

one #14–#4 AWG copper
one #12–#4 AWG aluminum
two or three #14–#10 AWG copper
two or three #12–#10 AWG aluminum

Line Lugs

All lugs suitable for 75°C copper or aluminum wires.

CSEDs have wire binding screw torque values on the wiring diagrams and circuit breaker labels.

Phasing

CSEDs have distributed phase bussing.

Most branch circuit breakers can be mounted in any position.

NEMA Type 3R – Rainproof

QO and Homeline Meter Mains

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. This style of enclosure does not have a gasketed sealing surface. Some models have hasps for padlocking.

Square D by Schneider Electric CSEDs are suitable for use as service equipment only in residential applications where local codes require service disconnects to be located outside the dwelling.

QO and Homeline meter mains have different physical qualities, yet they both fulfill the same function. Contact your local utility to know which metering enclosure to use in your area.

Circuit breaker format - QO: ¾ inch per 1 pole space/ Homeline: 1 inch per 1 pole space.

Meter socket type - QO: Ring type and ringless / Homeline: Ring type and ringless

Backed-out neutral terminal screws - QO: Top and split neutral/ Homeline: Fully distributed split neutral

Bus bars - QO: Shielded, tin-plated copper / Homeline: Most are not shielded, tin and copper plated aluminum

Meter Main Rainproof Enclosures

	QO and Homeline Plug-on Neutral (PoN) Plug-on Neutral CSEDs are an available option that 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 time and wire, allowing plug-on neutral circuit breakers to connect directly to the neutral bar without the pigtail.
	Material and finish Galvanealed steel enclosure includes interior trim and door with a gray powder coating. QO interiors have tin plated copper bus bars and Homeline interiors have tin and copper plated aluminum bus bars.
	Stainless steel latch A stainless steel door latch on the enclosure provides closure and maximum durability.
	Wiring access without door removal CSEDs are side-hinge or top-hinge door devices, providing full wiring access without door removal.
	Hubs Square D type rain-tight hubs provide fast and convenient top or bottom feed conduit connection. Hubs are suitable for use with conduit having ANSI standard taper pipe thread. Closing plates available for A, A-L and B hub openings.
	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.
	Different meter socket types Ring or ringless type meter socket designs available. After all work has been done and the meter has been fastened, a sealing or locking mechanism is placed in either form. Check with your local utility the sort of meter mounting to be utilized in a given location.
