re. my recent panel post
1. i did venture into what i considered an unsafe setup of my main panel (switch inside and the feeder wires still hot regardless of on/off). i replaced some 20 amp breaker to which, idiotically, 14 gauge wires had been connected, with 15 amp breakers and went even as far as introducing a whole new 15 amp circuit. apparently, i did not touch a hot feeder.
2. once i did this, the flickering light started functioning properly, as it was no longer being supplied by the old armored ungrounded cable but with the new circuit described above.
you guys were helpful so you'll be hearing from me more ...
