Service Installation
COURSE DESCRIPTION
This course describes basic procedures for installing and connecting services. The course describes common types of service connectors, and demonstrates the basic steps involved in making a service connection. The course also demonstrates procedures for installing both overhead and underground residential services. This course describes three types of voltage tests that should be performed before making service connections. The course also describes procedures involved in installing a three-phase service and replacing a three-phase service without interrupting service to the customer. Typical safety practices and job preparations are also covered.
