Circuit trips partially


For the past couple of days we have had one circuit in our house that trips for only an hour or so and does not trip fully. In other words things plugged into this circuit will go on and off as the circuit is going through this process.

Weirdest part is that it only lasts for about an hour and has happened at the same time each day. After this hour there is no longer an issue with the circuit.

Any ideas??

Check for loose neutral/hot wires.
Daily temperature fluctuation could account for when this happens... (open cold, closed when warm and contact is made)
Not sure this is the problem, but it could be.

This is not tripping. This is a sign of a loose connection. Loose connections can lead to fires from the heat build up. Get this fixed as soon as possible.

You should probably start to look at the switches or receptacle on that circuit that receive the most usage. After that it will be an easter egg hunt until you find it.

The thing that confuses me is why doe it only happen at a certain time of day and only for about an hour. Could this be from a surge in the area?

As a connection heats up from usage it will expand. When it cools it contracts. The connection when loose will act like a spark plug gap.

So that will cause this issue? I could grasp this if we removed something from the circuit when it does this but we don't we still have the same things running through it.

I am certain that Jim would know better than I, but it also occurred to me that, depending on the age of the house, and what changes have been made over the years, it could be a compatibility issue with aluminum wiring and improper receptacles, in which case this circuit may only be an indication of a wider problem; not insurmountable, just wider. Either way, it needs attention, and unless you find an obvious loose connection, you may be wise to involve an expert.

Jim cover few parts here and let me expand little more start check with the receptale and switches first that is most common cuprits second common cuprit is loose wirenuts both can cause alot of issue. { backstabbed receptales is famous for this so move it to the screw }

What part of the house circuit that is affecting so we can able steer ya in correct way.

Marc

When this happens it takes out our living room and bedroom but the rest of the house is fine. On this circuit we have a television, DVR, 2 pc's and a fan.

It does not have to be an aluminum issue, but that is a possibility. A loose backstab could also exhibit the same issues.
