Default Light bruns out quickly, appliances gone bad

Hi all

I have a customer that his appliances went dead ( green board) and his lamps needs to be changed frequently,
He has a warranty on the appliances but they say it's not covered due to an electric problem, I check voltage line 2 line which 240. Line -Neutral 120v . All connections looks good what could be the problem, any suggestions help is appreciated
Thanks

You need to check the voltages with a load (like a hair dryer or heat gun) on just one leg and see what the voltages do. If the one with the load on it goes down in relation to the neutral and the other leg goes up in relation to neutral, and the L to L voltage remains the same, you have a deteriorating neutral connection.

Also, tell them to call the POCO. Around here they can typically get there the same day to check the connections on their end.

That is a classic sign of loose or bad netural connection.

Do a quick load test as hardworkingstiff mention about that and watch the line to netural voltage change on that.

Of course get a hold the POCO same time they will check their side after you get your side done and watch them to make sure they verify it.

typically bad netural connection on their side can show up a bit so expect that after you check all the connection at breaker box.

i would check & clean all neutral connections. had a friend that had the same problem. he got home one night & looked like someone had turned a spot light on. shut off main called power company, they cleaned & checked all neutrals. all was ok till next night , back again, this time they found they had a bad neutral at the transformer. only it was on the inside not outside. had them stumped too. changed it at two in the morning. no more problems since then.
