43a Customer/Contractor Contact the company for the point of attachment for new serv-
ices or if the service point attachment changes. Connectionsmust be accessible by ladder from the ground at level grade.
Determine the location of the service drop.
Ensure that the point of attachment is not less than 12 feet ormore than 25 feet above final grade. The point of attachmentmust be of sufficient height to provide minimum clearances.These clearances are required by the NEC, Article 230, andvary dependent on the type of service and types of terrain the
service drop crosses. Provide and install service drop attachments for single-phase
services
(600-volt insulator applications). Generally, an overhead servicedrop is limited to supply service equipment rated 800 amperesor less. The company recommends an underground service fora service larger than 800 amperes.
43b Company Designate the location of the service, if there is an obstruction
or clearance issue.

SECTION 4
49a Customer/Contractor Consult the company if requesting an underground service
lateral from the companys overhead line.
Install and maintain the service cable.
Note: For residential services, the company recommends theuse of a single three-phase conductor (2-4/0 & 1-2/0) alu-
minum direct burial 200 amp. 600-volt cable for up to 250 feet. Choose between these two options if the underground serv-
ice is longer than 250 feet:
1. Install a metering pedestal as detailed in Section 8
2. Request the installation of primary cables and padmounttransformer on the customers premise (premises)
Fulfill these requirements if Option 2 is selected:
Follow the Common Utility Trench requirements, Section420
Provide a trench according to company specifications fromthe companys distribution system to the transformer location
Provide an excavation on the customers property for thetransformer pad according to company specifications
Coordinate the installation of gas and/or communicationfacilities, if these will be installed in the same trench (refer
to Section 420) Consult the company before work begins so that the company
can locate the service point at the pole, the conduit locationfrom which service will be taken, the route to be followed, andthe meter location.
Note: The cable must be carefully coiled, capped, and fastenedto the pole above the conduit.
Install standpipe and bend according to Figure 17.
49b Company Install a pole and appropriate guy on the customer premises to
be served, if the companys distribution is on the opposite sideof the highway. Charges may be applied according to the TariffSchedules for Electric Service.
Allow only two electrical conduits on any company pole.

Require that all buried conductors pass a 1,000 volt direct current(VDC) megger test performed by the company, after the trench is
backfilled and prior to energization. The minimum acceptablemegger resistance value for new cables is 2,000 megaohms.

425 NonResidential Underground Service Connectionsfrom Overhead Lines Less Than 600 VoltsGeneral
A nonresidential underground service is a service that feeds single-phase or three-phase to a person, corporation, or other entity whois not a residential applicant requesting underground service fromthe company.
425a Customer/Contractor Consult with the company if requesting a single-phase or three-
phase underground service lateral from the companys overheaddistribution line.
Contact the company before work begins to designate the serv-
ice point at the pole, the conduit location from which service willbe taken, the route to be followed, and the meter location.
Note: If the municipality refuses to permit the overhead cross-ing, the customer is responsible for obtaining a permit, thenexcavating or boring, and installing the road crossing to the com-panys existing distribution facilities according to company spec-ifications.
Note: For nonresidential underground services, an exception
may be made for more than two conduits on the pole. The excep-tion must be approved by company engineering and meet theNEC requirements so that the service cables meet the serviceloading.
Install standpipe and bend according to Figure 31.
