Serviced a house Friday. Lights dimmed when the stove and oven (electric) was turned on.

Lighting was fluorescent.

Checked the panels for bad breaker / connection etc..

Ended up at the box behind the stove. Box and connection looked new.

The cord connection for the stove, neutral was tight, one conductor was a little loose. The other conductor was loose and the stud was melted.

I don't know why this would produce symptoms of lights dimming. Sound similar to this situation.

First make sure you have 240 volts coming into the line side of the panel. If you don't that is the problem. If you do then you have lost a phase somewhere and are feeding back through the motor or contactor in the A/C. more than likely you will not be able to run any 240 volt appliances if you only have 1 phase coming into the home! The clue should be that 1/2 of the lighting works.

i went to bed, and slept in late as well... after posting what i felt was a
witty rebuttal so a somewhat rude post, and then george got up early,
and deleted about half of the thread..... i didn't get to read the downward
spiral, or take umbrage at my besmirched talents, or *anything*..... snif.

but... but... but.... george......

bless his heart, he's never seen the photos of the
van, or gotten a load of my "tool time" posts. ;-)

but after breakie this morning, when jill took off with her sisters to
christmas shop, i was bored, and it wasn't raining, so i hopped in
the van, and did a drive by on the house, as it's empty, and nearby,
and slapped a fluke 12 meter on the load side of the main, to see if
it was hot on both sides, which i had not done on the initial service
call, as i had a realtor in a hurry with me the other day,
who wanted a speedy diagnosis.

with the AC off, it's hot on both legs of the main.

;-p

now, it could be intermittent. wished i'd taken the time to pull
the panel cover and check the other day, as i could not go
inside the house to check voltages today.

the most likely problem is what the group consensus here came up
with, that there is a open leg, either in the poco feed, or in a bad main
breaker.

with a small but vocal minority opinion that i'm an idiot.
while that position does have merit, i'm feeling smarter than
normal this morning, and so i suspect the following.....

if it's not an intermittent issue that wasn't repeating this morning,
then there is an open neutral, and the 220 motor load is acting in
somewhat of a bizarre fashion, to generate the appearance of a
neutral path where one does not actually exist.

and, to prove that i am in fact an electrical contractor, i was contacted
by the buyer yesterday afternoon to provide a written quote to rewire
complete and patch any holes made in the process, for $10,000 complete,
before escrow closes, to be paid out of escrow funds.

10k? paid out of escrow? on todays icky work market? yes, sir, i can do
that. which is the real reason i was prompted to go over there this
morning, and do some checking.

insulting me isn't enough to get me to do something. you have to be
willing to pay me, too....

there.... does that qualify me as an electrical contractor?

enjoy your sunday, one and all.......

Just A late follow up on troubleshooting procedure You must MUST!! turn off all ALL 2 pole loads as if any are on they will backfeed the bad leg. The ultimate test is to shut off the main and check to see 240 on the line side of the breaker. Kind of late but this stuff can ruin a closing.
