I have not participated on this forum before and decided to do so having read some of the q&a's which I found most helpful.

Over the last 2 weeks I noticed some of my GU10 50w's flickering, fluorescents also flickering and last night a CFL on a plug point. I spent time trying to isolate the cause as I normally suspect dimmers....I could not find the fault but noticed that one of my phases (checked unloaded) has a reading of 209v whereas the other two 236v. It is really the CFL on the plug point flickering that made me think that it is not a demand side problem. I then swapped phases and the flickering is gone. Could it be that it is a corroded / burnt etc breaker on the pole maybe? Thanks, would like to know your thoughts.
