As a sparky one thing that gets me is flickering lights - (along with buzzing) especially in my own home. I can not help myself from instantly starting of diagnosing the problem every time it happens - even if at a friends home, or in a restaurant - anywhere - anything.... It's a compulsion I am sure some of are inflicted with.
Anyway, a few days ago some lights started flickering around the house - I would have to ask and confirm with the wife - "Did the lights flicker? Or did I just blink?" Answer - yep - Flicker.... So last night a dove into the sub panel all those lights were on and look around, have the wife crank up the garbage disposal while I went around with a meter - a little but acceptable .5v voltage drop, no mis-matched amperage's - nothing went up in voltage...... I get done - then it happens again on lights not from that panel - out of the main..... OK - in the morning I go out there and check - yanked my meter - OOOOOOOOO a little corrosion, I'll be doing a service change this next summer - but no real problems - tightened the lugs just for SOP.
Right before I'm going to bed that night - more flicker....
Lost my IR thermometer a while back and just plain ol' left it somewhere - I was driving around today between jobs - thought that's it, better get a new one, and so I did - Fluke 62mini. Got home turned on every light, fan, bath heater, radio and what have you, (Unplugged the 'puter) and started scanning wires, breakers, buss-work - bent over backwards to get some good aim up under the meter section of the main - then the service drop. "It's always the last place you look"
Ambient temp ~65 (65-70 on just about everything)
Phase A
~65 my side ~65 on their side ~65 on the splice
Neutral
Same as above
Phase B
~70 my side -71 their side - 128F on the splice
