Electrical Issues on Main Panel


http://youtu.be/kwy7_VWNqbo Just below my main breaker (200 Amp) box, on the left pole of the buzz bar there are sparks coming from around the hex nut. Now with all breakers on, if you turn on the A/C unit, it runs for about 5 minutes or so and trips the "Main Breaker", not the A/C breaker. The other way the main trips, is if a lot of circuits are being used, fans in all rooms, lights, and turn the electric burners on the stove on, it will trip... roughtly after 5 minutes or so. The electricity was just turned on at the house because people are moving in. The electricity has been shut of for about 4 months now due to it being vacant, however, prior to that it was running with no issues. The Electric company came out and declared the meter is good and to call an electricitan. Anyone know my issue? Is this an easy fix?

Electrical Issues on Main Panel


Loose connection, heat buildup is tripping out the main. The guts of that panel are toast, and I doubt that merely attempting to tighten that nut would be a sufficient remedy.

Call an electrician is good advice.

The good news is it hasn't caught fire yet. The bad news is it probably will soon if left as-is. Leave the main breaker off until you can get that looked at. As kbsparky says, all the heat and arcing from that loose connection may well have done some damage to the guts of the panel. It definitely needs to be evaluated by an electrician.

So by loose connection, i'm assuming that is being directed at the nut? Is there a reason it cannot just be tightened? Guts burnt to a toast? are you being metaphoric, or are you saying there are other issues that are not visible, or in a best educated guess opinion, could be wrong that is causing the arcing around the nut?

Personally, I wouldn't be comfortable with just tightening that connection without inspecting it first. Loose connections arc, as you noticed, which causes burning and pitting of the metal, and can result in a poor connection even after tightening. Loose connections also get very very hot, and that heat can damage the surrounding plastic components and main breaker.

The connection (nut and stud) has gotten so hot that it is tripping the breaker. This has not been a short term problem.

The fact that this has been happening for a while means that in all likelihood simply tightening the nut is NOT a safe or effective fix at this point as the metals have changed properties.

If the panel is not that old you may be able to have just the internals replaced.

Are you the owner? Renter?

Yes, i am the owner of the property. I have tenants moving in next week and they had the electric turned on in the house, but when i went over to inspect the HVAC and hook up gauges, of course i had to wait a period of time to get pressures up & thet is when i noticed the main kept tripping. I am not looking for an easy fix, but if this is something that i can deal with, by all means i will educate myself to handle it, however, if this is a difficult issue to both diagnose and fix, then money well spent to the professional.
