Question:

Why do my lights flicker with my portable generator?

I live in southern Indiana, and am currently living through an awesome ice storm. Anyway, my parents bought a diesel powered portable generator. It is hooked into the main panel of the house. When you crank it up and turn the lights in the house on, they flicker, as does the TV screen. It has proper voltage on each leg of the 240. I brought my generator over and everything works fine. Any ideas?

Answer:

some where your not getting a secure connection,but look at it this way,it beats not havin power,a little flicker here and there is better than no flicker at all, i bet the people that has nothing is wishing for a flicker
You haven't told us the generator wattage. Your generator must have enough to power the house properly, or the unit they bought is defective.
The generator would seem to be working above its recommended constant or optimum load. It could be too small for the demands it could be of lower quality it could be a defect it could be a dirty carburetor or injection system it could be dirty fuel or or ice in the fuel lines. All the things that can make your car run badly can also happen to generators. Most people install them and forget about them till an emergency without good preventative maintenance sometimes they fail when you need them most.

if you hooked another generator to your panel and it worked fine the new generator is the problem. unless you changed the way you hooked it up. in that case look at your connections, closely at the ground for sure
