more information



INSPECTORS: PPL Electric Utilities has converted to a new work management system that uses 8-digit workorder numbers. You should expect to see 8-digit numbers for newer jobs. However, there could still be some older jobs that have 6-digit numbers because they were established in the old system.

  • Only electricians authorized to participate in PPL EU's Fast Track Program may alter PPL EU meter seals and make permanent connections at the customer's point-of-contact with PPL EU's distribution system. See Rule 1, J and K .

INSPECTORS: Please help PPL EU prevent unauthorized alteration of our facilities by enforcing these provisions of REMSI.

  • It has been brought to PPL Electric Utilities' (PPL EU) attention that when an inspection is failed, a second inspector is being brought in for re-inspection. This does not follow PPL EU's guidelines for multiple inspections.

Please see the Electrical Inspections section for more information.
