I replaced the wire from the meter box up to the service connection because it was damaged last winter when a tree pulled the wire from the house - although the service man said it was still sound the outside casing was ripped in a few places and should be replace someday. (since we were having the house sided I thought that would be a good time to do it) Had a disconnect put up a new wire. But now the light seem to flicker more when the water pump comes on and when we start the microwave after a few seconds it sounds like it drops in power. I tried not to tighten the lugs too much - said 50lb torque and did that - the clamps didn't look dirty but I also didn't clean them - where should I start. - will cost to have another disconnect.
