I am having a very disturbing electrical problem. Two or three days ago, some of my lights at home would occasionally blink, dim, etc. As an electrical storm was passing in the distance, I thought nothing of this occurrence. Yesterday, I turned on the bathroom light, it blinked, then went out. Aha.. The bulb blew, change the bulb, turn on light, . . . nothing. Take old bulb; try in living room lamp, Tada, light. Put new bulb tried in bathroom light, Tada, bulb works. Re-install bulb back in bathroom fixture.
I went to the electrical panel to check the breakers and found none to be tripped, (mix of one and two pole breakers in 3 wire, 120/240 volt, system, [three 4/0 aluminum wires enter box at top]). I then checked around the house and found power in some rooms and none in others.
I recycled all of the single pole breakers (15 & 20 amp mix), one by one, . . . nothing. I turned off all breakers, the main breaker included, turned main on, then each circuit breaker, one at a time. As some of the breakers are labeled, I have spouse check specific rooms and appliances. This working, that's not. Turn all breakers off again . . .
To make a long and frustrating story short, through process of elimination, I find all circuits connected to the left hand buss are predisposed to failure. By turning on something connected to a circuit on that buss, the whole buss goes out, without any breakers tripping out. This is my reason for concern.
Any and all help would be greatly appreciated, ASAP.
Thank you all in advance,
