Electrical wiring problem?
I have a house that has been a puzzle to the local electric company and other professional electricians. The lights seem to burn 'low' or dim and small appliances such as fans run at below normal speeds until some additional load kicks on. Then the lights 'brighten' and fans speed up to normal operating speed. It seems to be a whole house problem and not limited to a single circuit. For example, the A/C can kick on and brighten the lights. The A/C is, of course, on 220 circuit by itself. The refrigerator, toaster, microwave, all have the same effect. And you should see what the washing maching does on the agition cycle!! It pulses the lights in time with the agitator. Now we know why it is called the "agitation" cycle.
The electric company has tested their transformer and says it is not them.
Have you seen this before?
Answer:
I agree with nubby, in the mean time you can check your grounding in the house... where the panel is bonded to the water line, and your grounds going outside, you should have copper ground rods driven into the earth, if you have a newer service there will be two. follow the 1/4" wire from the wall that your panel is on to the dirt and dig it up, tighten these connections if loose. the electricians that you called before should cut you a break on the hourly if they didnt figure it out before... if they are good businessmen.
you can also check for errors in the neutrals to see if it is particular circuits by shutting off one home run at a time (220v and higher load 120 appliances) and see if it doesnt occur when one is off. if you find it turn it off. if a neutral is overloaded it is a huge fire hazard. good luck
