All breakers in panel trip?
 
I'm a lineman for the power company and went out on the same job twice now.

Speaking with the customer I was told that every breaker in his panel was tripping several times a day after about 18:30 till 24:00. Every breaker, even the main 100a, even the spare breaker with no load wire on it would trip. They all trip at the same time.

It's a mobil home converted to a house (expansion mansion) He hired an electrician and has spent $2,000 on repairs to include a new panel.

There is nothing wrong on my end.
Any Ideas

The panel is in his house, and he has documented resetting them up to 32 times in one night.
I told him to get another electrician before he burns his house down.

He needs a new electrician.
He needs to stop resetting his breakers.
He is full of crap!

He hasn't told you the entire story and I cannot think of a situation where what he describes could happen outside of 32 lightning strikes every night. I would however be willing to buy a case of what ever he is drinking .... :)

The only other thing I can think that would cause this (and it's SO FAR out there as to be nearly impossible) is excessive heat on the bus being conducted into the breakers and setting off the thermal trip. Setting up a peak current detector would tell you whether it's tripping due to a spike or an overload.

Just thinking.
 
The original panel in the mobile home would have been wired as 4 wire sub panel. The frame would be bonded and the water.

If the addition is wired like a residential service and the grounds and neutrals aren't separated that might cause all sorts of strange problems.

What might happen if an original 4 wired sub panel is bonded back to a service grounding electrode with out the grounds and neutrals isolated.

Talk about parallel paths.

Check the neutral going to the original panel in the mobile home. Make sure that neutral is good.

Just thinking.

You would simply have neutral current on the ground but all the breakers would not be tripping.

Only thing I can think of that might cause lots of crazy events would be if the addition has a main lug panel being fed from the panel in the mobile home and he has a hot feeder conductor terminated to the neutral bus and the neutral terminated to a hot bus lug.

Not sure if I have my head wrapped around that yet as to what that might cause.

Surely an electrician that has charged $2000 for repairs would have found that, even if only by accident!:whistling2:

I claim that it is impossible for all the breakers, including the main breaker and a breaker with nothing screwed onto its load terminal, to trip all at once.

Hourglass52 02-11-2011 04:14 PM

Nothing is impossible. I would love to work on this problem to see what is up.

Oh I agree 100% but then we haven't met the electrician .... :)

Yeah it does seem pretty darn impossible, so I agree and that is why I said we don't have all the story and most likely it is just that ..... a story.
