Approved Meter Connection DevicesINFORMATION & REQUIREMENTS FOR METERCONNNECTION DEVICESI.BASIC REQUIREMENTSWith regard to meter connection devices that are approved for use in the ComEd servicearea, the basic requirements are as follows:1) All meter connection devices must have CECHA stamp.2) All meter connection devices must have ringless covers and reinforced jaws3) By-passes are required on all meter sockets (horn type on single-phase and lever armtype on polyphase.The above requirements are listed on each of the manufacturers’ pages in this catalog tofurther emphasize their importance.II. TYPICAL METER CONNECTION DEVICESThe arrangement of meter connection devices will generally fall into one of the followingcategories:1) Single position overhead2) Single position underground (with raceway)3) Multiple position horizontal grouped sockets (overhead or underground service)4) All-In-One type multiple position metering unit (overhead or underground service)5) Vertically grouped sockets (multiple position; indoor or outdoor)6) Switchboard type metering panels (multiple position; indoor)Diagrams of these various categories are shown in Exhibit A.Categories 1 through 4 above will generally be installed outdoors. The vertically groupedsockets (category 5) can be installed indoors or outdoors. The installation of verticalsockets will be covered in greater detail in Section V. Category 6 (switchboard typemetering panels) are designed for indoor installation, mainly in commercial buildings.III. METER MOUNTING HEIGHTSMeter connection devices must be installed at heights where meters can be installed andread safely by meter personnel standing adjacent to the meter. Access to meters bycrawling on hands and knees or by standing on a ladder is not acceptable. The minimummeter mounting height is 30-inches, and the maximum height can be 60 to 72 inchesdepending on the type of meter connection device. The minimum and maximum metermounting heights are shown in Exhibit A.Revised: December - 20151

Approved Meter Connection DevicesINFORMATION & REQUIREMENTS (Continued)IV. RACEWAY REQUIREMENTS FOR UNDERGROUND SERVICEWherever an underground service is to be connected to a meter connection device, araceway must be used to route the cables to the terminals within the device. This isevident in all the single position underground devices that are currently CECHA listed,asthey are all designed as a combination meter socket and raceway. This is true of bothsingle-phase and polyphase units. With regard to the multi-position units such as the AllIn-One type or the horizontal grouped sockets as shown in Exhibits A and B, a raceway isrequired on all underground service connections to these units. These raceways areavailable from some socket manufacturers and local switchboard builders.V.REQUIREMENTS ASSOCIATED WITH VERTICALLY GROUPED MODULESVertically grouped meter connection devices (meter modules) are generally available in2, 3 or 4 positions and they can be bussed together to provide multiple meter points at asingle location. An example of where these meter modules would be used is in a multistory building in meter rooms on the various floors of the building.These meter modules are always installed with some type of main device which can be atermination box, fused switch or circuit breaker. The electric service supply willterminate in this main device, and the meter modules will be internally connected to thismain device by buss bars.The main device can be connected directly to the adjacent meter modules if both unitshave the same front to rear dimension (or depth). However, if the main device has agreater depth than the adjacent meter modules, a spacer is required between the two units.Exhibit C outlines the conditions where a spacer is required. In the majority of thesetypes of installations utilizing vertical meter modules, a spacer will be required betweenthe main device and adjacent meter modules. Exhibit B also outlines meter moduleinstallation on adjacent corner walls in a meter room and frontal clearance requirements.With regard to the meter mounting heights outlined in Section III. above, a 4-positionsingle-phase module and a 3-position polyphase module is the maximum size that can beused which will comply with these dimensions. In some cases, installation of 5-positionsingle-phase meter modules will be allowed, but prior approval is required from SystemMeter in Oak Brook.VI.

Approved Meter Connection DevicesThe following notes apply to all meter connection devices that are used inComEd’s service territoryNotes: 1)All meter connection devices must have CECHA stamp.2)All meter connection devices must have ring less covers andreinforced jaws.3)Bypasses are required on all meter sockets (horn type on singlephase and lever arm type on polyphase).4)The use of 5-position vertical meter modules must be approvedby System Meter prior to installation of the equipment. ContactSystem Meter Dept for requirements.5)When using switchboard type metering equipment, it is arequirement that prints be submitted on each project where theequipment is to be installed. These prints must be reviewed andapproved by System Meter before the equipment is installed orenergized.6)These units are to be used as filler or replacement modules inexisting Cregier Mark VII meter stacks. They are not to be usedfor new construction projectsRevised: December - 20155
