Service entrance equipment

Determine the meter base/socket location, the service line route, and the size of the
service you want (for example, 200 A), before you begin installing your service entrance
equipment.
Installation • Service entrance equipment can be installed either flush-mounted or surface-
requirements mounted (see Figure 10).
• Install the meter base/socket so that the center of the meter will be between
4 and 6 feet above finished grade with a 5-foot height being preferred.
• The service entrance conduit has a maximum of one 45-degree or 90-degree
bend with a minimum 24-inch radius.
• Do not install “LB” joints, conduits, or devices that allow access to the service
conductor in the riser ahead of the meter.
• A current transformer (CT) enclosure, if required, must be mounted on the
outside of the structure it serves.
NOTE: Service entrance equipment for a 401−800 A installation is shown in Figure 11.
