<strong>2011</strong> <strong>Electric</strong> <strong>Service</strong> <strong>Requirements</strong>, 2 nd Edition<br />
Section 7<br />
7.7.2 Underground <strong>Service</strong> to Wall-Mounted Meters<br />
Installation requirements for underground service to wall-mounted meters are listed below.<br />
These requirements are in addition to the general requirements given in Section 7.6 and the<br />
requirements for underground service in Section 7.7.1.<br />
<strong>Requirements</strong>:<br />
1. The meter base and conduit shall be securely attached to the structure.<br />
2. The meter socket shall be plumb when inspected.<br />
3. 2” x 4” back supports or 5/16” molly screws are required.<br />
4. Conduit and sleeve are required when passing through a paved area adjacent to<br />
building foundations.<br />
5. Manufactured or field bends made of PVC matching the quality of factory bends may<br />
be used directly under the meter enclosure to align the ground riser sweep with the<br />
meter socket. Field bends shall be free of flattening, cracks or burns. The minimum<br />
bending radius shall be 36”. The contractor is responsible for proofing all conduit<br />
systems.<br />
6. For brick veneer or concrete block, a 1/4” x 3 1/4” lead sleeve expansion bolt in the<br />
joint shall be used in place of lag screws on anchor straps.<br />
7. The meter enclosure knockout diameter shall be able to receive the conduit riser.<br />
When 3” conduit is required and a flush-mount meter enclosure is installed, a 2”x6”<br />
stud wall must be constructed. See Section 6 for conduit requirements.<br />
8. When a 3” knockout is not available, a swedge may be used to transition to a smaller<br />
conduit size. <strong>Power</strong> Company approval shall be obtained prior to installation.<br />
9. Above-ground conduit shall be Schedule 40 PVC or better. Some jurisdictions may<br />
require conduit grades better than Schedule 40; consult the local governing code.<br />
10. The electrical label or permit shall be displayed on the meter base.<br />
Figure 7.7.2 shows a typical installation of a meter and associated hardware for surface<br />
and flush wall-mounted meters.<br />
