Hello,this is my first post here.I have a 10 year old home with a 200amp
service.While I am in the garage,every once in a while I hear a loud bang from
the breaker box.It does not trip any breakers. My son down in LA(an
electrician)says might be a loose wire. He advised me to
switch the main breaker off,and check each breaker for loose wires or marks from
arcing. I found no marks or loose wires,if it was consistent I would be tempted
to find out which breaker is making the noise and change it. At this time I am a
little stumped as to my next step, Any Ideas?
Thanks in advance!
Are you positive the banging is coming from the panel?
If so, do you notice a flicker or dimming of the lights when it occurs?
If the answer is Yes and then No, I would invite your son up for Sunday
dinner and ask him to bring his tools<g>
Only thing I can think of is maybe a GFCI breaker but that - of all
breakers - should trip completely. If you have a GFCI breaker(s) in
that panel, have you tried testing them to see if they work and/or sound
similar to the noise you're hearing?

GFCI breakers,but neither has tripped.Actuelly 1 has tripped in the past and we
found a short in a light fixture.Once I replaced the fixture,no more
tripping.The noise may be bigger to me,I am deaf and wear a hearing aid and have
a cochlear implant,but the noise is still there.As for bring my son up for
dinner,he is in Los Angeles,I am in north Idaho.
From what you have said, everything appears to be working normally. Has
anyone else heard the bang? It could be a magnetic spike that your
hearing electronics are picking up.
Gfretwell's suggestion that there might be a magnetic kick vibrating the
breaker box cover is plausible. I would look at the breakers for large
loads that cycle periodically, such as the air conditioner or water
heater. If you could turn off one breaker at a time, you might be able
to isolate which one is the culprit.
If there are two identical high current breakers, try swapping them and
see if there is any change. The AC, stove and water heater breakers are
candidates, and are probably twin breakers for 240 VAC circuits.

yes that is a very good observation
there may be an electrical interference with your hearing aid and not an actual sound
if this is the case, there is nothing wrong, you are probably "hearing" the electrical surge of the fridge or some other motor starting
Has anyone else actually heard the "bang" when you hear it? Since nothing
has been found, I would be very suspicious that something is generating a s
ignal that is getting into your hearing system. Is the breaker box in the g
arage where you are when you hear it? Is the garage attached to the house
or a separate building?
Is there a time of day or day of week that this happens, or it it apparentl

I would be very suspicious of some outside noise sounding like it is coming
from the breaker box based on all the information yhou have given us to da
te. For instance, a bird flying into the house wall near the box, or maybe
some strain being relieved as the house expands or contracts with changes
in temperature, etc.

+1 to all that.
Before spending money on an electrician, I would at least make sure someone
with normal hearing verifies that they think it's coming from the panel.
It would be very unusual for a real noise in the form of a loud bang to com
from an electric panel, with no other symptoms.
WOW!yes,some one else has heard it,no my implant has nothing to do with
it,garage is attached(built in 2004 with the rest of the house)I have switched
out breakers,checked wire for tightness,pulled outlet covers to check for the
same.An electrician has the tools to check wire temps,hot spots etc.The bang is
inconsistent,after the bang,the next one might be an hour or 5 hours.I have shut
off circuits to try and narrow it down with no luck.Better to spend the money on
that as opposed to burning the place down.Thanks anyway.
I agree with the others that the issue/problem/anomaly is probably with your
cochlear implant and not with the electrical panel. Can you tell the
direction that sounds are coming from with your cochlear implant? Do you
have unilateral hearing with your cochlear implant(s) or bilateral hearing
(since personas with unilateral hearing cannot detect the direction that a
sound is coming from).
I think that you may be better off contacting the specialists who are
involved with your cochlear implant rather than an electrician. Or, at the
very least, have an independent person with normal (non-assisted) hearing
verify that there is a loud bang coming from the electrical panel before
calling in any electrician.
Good luck and let us know what the final answer is on this one.

I guess you didn't see his post where he said that others with normal
hearing can hear the bang too. IDK what it could be either, makes no
sense to me, but apparently we can rule out his impaired hearing.
That sounds like a hot water heater cycling to me. You would know if
the stove was in use, and an air conditioner would cycle more frequently.
Your electrician may be able to access the water heater thermostat and
manually cycle it. Make sure he resets it to a safe temperature!
