RULE 26 - CUSTOMER'S EQUIPMENT -- STANDBY GENERATING EQUIPMENT

a. Standby Generators:

Customer may install a standby generator(s) to provide all or part of existing load in the event of an interruption in PPL EU's service.

b. Consult PPL EU Before Installation:

Customer shall consult PPL EU prior to installing standby generators.

c. Method of Installation:

The customer shall install a double throw switch or mechanically interlocked circuit breakers so there can be no electrical connection between PPL EU's service and the customer's generation.

The double throw switch may be operated manually or automatically. The double throw switch or mechanically interlocked circuit breakers must be rated adequately for the voltage and current levels.

When the National Electrical Code (NEC) or any other applicable code permits and the customer chooses to install the double throw switch or mechanically interlocked circuit breakers on the service side of the customer's main disconnect and over current protective devices, the double throw switch or mechanically interlocked circuit breakers must be listed for use as service entrance equipment.

Installation of a pole-top fused double-throw switch is not permitted. See Sketch #41, Sketch #41A, Sketch #41B, and Sketch #41C.

d. Emergency Lighting Systems:

This rule does not pertain to generating equipment and wiring installed by a customer to meet the requirements of the Pennsylvania Dept. of Labor and Industry for Emergency Lighting Systems.

PPL EU does not recommend size, location, method of connection, or approve the operation of the above emergency lighting equipment.
