Meter Socket · 200A main, 100A per position, 3-gang, OH/UG, Type 3R · Left-hand service entrance and cable entry trough · Eaton 3KN1

What this product is for

This 3-gang meter socket is used to group three meter positions in one enclosure for combination overhead or underground service. It is suited to residential and light commercial metering layouts where a 200A main bus with 100A per position matches the service design and utility requirements.

Use for

• Three-position metering assemblies
• Combination overhead or underground service entrance installations
• Projects needing a Type 3R outdoor enclosure
• Copper or aluminium conductor installations within the published lug ranges

Avoid for

• Applications requiring 200A per meter position
• Installations that need a factory 5th jaw as standard
• Jobs where the serving utility requires a different socket configuration, bypass type, or approval variant
• Indoor-only equipment rooms where a different enclosure style is specified

Best for

Best for electricians and contractors standardizing multi-tenant or grouped service metering with three positions in one enclosure. The factory-bussed trough and left-hand service entrance help simplify layout and wiring on approved OH/UG services.

Installed in

Typically installed outdoors on residential multiplexes, small multi-unit buildings, and light commercial service entrances. Enclosure size is 12-1/8 x 31 x 5 in (308 x 787 mm x 127 mm), which helps with wall layout and service planning.

Why this product exists

This model combines three meter positions into one Type 3R enclosure to reduce field assembly time and keep grouped metering organized. Eaton lists a cable entry trough as a standard feature, with the trough factory bussed for 200A from the main lugs to the line side of all positions.

Compared with similar products

Compared with larger K2 series units, the 3KN1 uses a more compact enclosure and is rated 100A per position rather than 200A per position. It also supports combination overhead or underground service, while some related underground-only models use different catalogue numbers. A typical buying check is whether the project needs 100A or 200A per tenant position before ordering.
