Filckering Lights and Sparks

[mphillipps]

A client called and said his home lights were flickering (more so when it rained). After witnessing the living room lights flicker, I pulled the cover to the service entrance panel and saw two of the breakers intermittently spark.

I replaced two of the breakers (badly pitted) and moved then to new unused post on the bus bar and applied Noalox? anti-Oxident compound.

Three day passed with no flickering lights but then it rained and his lights began to flicker, slightly.

The panel is a Challenger 125 amp lateral and the house is circa 1975 with CU wires.

A side from a complete R&R of the panel is here something easel that I should be doing?

Are all the lights flickering?

Loose connections maybe. Main breaker crapping out from water damage.

Is the main a large red horizontal body that plugs onto the two top bus stabs? If so, I bet the lower stab is burned.

....... and applied Noalox? anti-Oxident compound..........

Why?

 

[mphillipps]

I used Noalox because of the North facing, shaded and damp area where the service is located.

Is there another product that would help contact and fight dampness?

No it's not.

Could be a neutral problem on poco side acting up or in the house.
