Customer Question

Flickering lights again today. Our electrician inspected the panel yesterday. Yet, today we are experiencing "flickering lights" still again. Called electrician again. He said the panel was OK so the problem must be external. Natl Grid tech came last week and said some lines might have been "bumped" during recent extensive construction work. How do we learn what the actual problem really is and how to we find a solution?

1) Flickering lights suggest a loose connection either at the customer premise equipment or at the electrical utility equipment.
2) Did the electrician confirm the proper torquing of the Service Entrance wires at the panel main breaker lugs, neutral bus bar? Did any of the lugs show signs of arcing?
Was the panel main breaker checked that it is not loose? Any signs of arcing on the panel hot bus bars?
Is the electrical service overhead or underground?
3) Did the electrical utility pull the meter and confirm proper torquing on their LINE side connection and at the LOAD side of the meter?
Has the electrical utility checked the connections at their transformer?
4) Any of your neighbors also experiencing flickering lights?

Thank you for the replies Jim.
1) In service issues like this, the problem is often a loose wire termination either at the meter lugs or at the main breaker lugs where the service entrance wires connect at. The panel and the meter can will both have a torque value and the lugs must be properly torqued to ensure a proper connection.
