How to select a Combination Service Entrance Device (CSED) using the Product Selector
Issue:
Selecting the appropriate Combination Service Entrance Device (CSED) for your specific application.

Product Line:
Combination Service Entrance Devices (CSED)
Square D™ All-in-Ones
Square D™ Meter Mains (Ring or Ringless)
Homeline™ Solar-Ready

Environment:
North American Products

Resolution:
Note: if the application requires only a load center without a integrated meter socket, see FAQ FA293376 for the selection process.

The CSED Selection Tool makes it easy to choose the correct product for your application.

Please make sure this is the correct product type for your application. A CSED is a Utility Meter socket with an integrated Service Disconnect and/or Load Center interior. ALL CSED are Single Phase ONLY and Service Entrance ONLY.


STEPS for selecting ONLY a CSED

NOTE: Obtain ALL the local Utility Requirements BEFORE selecting and obtaining ANY metering equipment.

ALL CSED are Rainproof (NEMA 3R) devices.
1) Does your local Utility require Ring Type or Ringless Type?
2) Does your local Utility require a Bypass on the meter socket and if yes, what type of bypass(Slider type, Manual, Test Block, Horn or Lever type)?
3) Does the device need to be Main Lug or Main Breaker (Main lug means there is NO Main disconnect and the device is designed for the NEC 'Six Service Disconnect Rule'.
4) Does the device need to be a Meter Main or All-In-One?
A) Meter Main device contains only provisions for 1 up to 6 Service Disconnects.
B) All-In-One device contains a Service Disconnect with an integrated load center, if integrated load center, how many full 1-pole spaces are required? (For example: 20 full spaces with no tandem breakers or 20 spaces, 40 circuits by using tandem breakers).
Note: a Tandem breaker is one that requires One Full Pole Space, but contains Two separate circuits.
5) Does your local Utility require the device to be Overhead or Underground feed?
6) What maximum amperage rating of the device does the application require (for example, 100amp, 125amp, 200amp, 225amp or 400amp)
7) Does the device need to be Surface Mount (means it mounts surface on a wall) or Semi-Flush Mount (means that it mounts partially in a wall and partially out)
8) Will a Plug-On Neutral Arc Fault Breaker load center be required?
