Thanks for all the info,I'm unsure of what wire size was used but I think they used #12 for homeruns and #14 to the lights. I was told there was a vacant lot next to the above ground Xformer.It wouldn't suprise me if they didn't load the circuits with 12-13 lights on a 15 amp circuit in my opinion might be some of the problem and I know the next time I see him I'll probably be going over to investigate myself (aaaaaagh) I hate troubleshooting others mistakes.
