Please be advised
- 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.
