Lights flickering in your whole house although could be caused by several reasons the main culprit is usually a bad loose connection.

This can also be caused by corroded connection.

Any loose connections can cause arcing are burning and lights to flicker.

There are also a number of other issues which can cause lights flickering when we talk about loading up circuits. We will get into that in more detail.

Why Are My Lights Flickering In The Whole House Sometimes?

Lights flickering are sometimes worse than others.

It really depends on the conditions to cause the lights to flicker.

If you have corrosion in your panel the connection may be more secure on dryer days.

As opposed to days with more humidity or more moisture in the air in the air it’s because the connection to become loose and the lights to flicker.

When your whole house is flickering this usually is a sign of something in your electrical panel or your connections coming into your house.

One other thing worth a mention. Is if you notice flickering during wind storms.

This could mean that you have a loose connection coming into your house on the incoming line from the power utility.

If you notice is only during rainstorms and you should contact your local power utility instead of your electrician.

They can come and look at the connections on the outside of the house to make sure that they are not loose.

That wire start slapping around in the wind storm outside it can cause intermittent light flickering problems.

Why Are My Lights Flickering In The Whole House And Is This Dangerous To My Electrical System?

Yes it is dangerous to your electrical panel.

When you have a loose conductors are corroded wires this causes heat.

The heat then causes arcing which is why you get an intermittent connection to your lights.

The arcing can actually cause a fire or more internal damage. This is why it is very important to have this corrected as soon as possible.

Additionally if you have devices that are malfunctioning for example dimmers outlets or anything associated this can also be a hazard as well.

Once heat builds up in the back of these devices it is hard to get it stopped without completely replacing it.

Can The Lights Be Flickering Because Of A Bad Breaker?

We have seen bad breakers cause issues with lights flickering.

Breakers can be a funny animal. Sometimes when the mechanism inside of the breaker especially in a humid atmosphere will start to not work properly.

This causes intermittent power issues to 120 volt loads for the load hooked to it.

This is usually just a simple breaker change out but you can have your electrician do for you.

If you have a double pole breaker supplying your light fixtures for example a three wire feed with 120 running to two separate circuits.

One of the sides of the breaker decides to become faulty.

This can cause intermittent light issues as well. So as you can see it’s not one clear issue which is why you need to consult your local licensed electrician to try to address the problem.

What About A Bad Fuse?

A bad fuse issue can be a little different story.

If you have an old fuse panel and you notice flickering or a popping sound from the fuse.

This is not the fuse itself.

Fuses either blow or they don’t.

The intermittent connection could be caused from the fuse block itself. We see this quite commonly.

This is some thing that you can do yourself before you call your electrician.

Pull the fuse block out of the fuse panel and clean the contacts up with some sandpaper.

You can then re-insert fuse block and see if this fixes the problem.

If it does fix the problem and you should be good for a while but at some point you should have the fuse block replaced.

Why Do They Only Flicker When I Turn Something On?

When you only have your lights flickering sometimes or when you turn something on this is an indication that you have too much on one circuit.

If you have lighting on with an appliance and you turn that appliance on and you will get a flicker in your lights.

This shows the time that you need to upgrade some individual circuits.

This also can mean that you have an intermittent lose connection like mentioned above.

Either way you still have to get this problem addressed.

You can also get a flickering from larger loads in your house. For example air-conditioning systems.

Heat pump systems. Or anything with the compressor in it that takes a large inrush amps to start up.

If you have other loose connections in your panel and the large appliances taking all the energy you will notice a flicker in your light fixtures.

Although this is a minor flicker you should not be concerned about this because this does happen and all homes.

How Can I Stop This From Happening?

Doing your regular maintenance on your electrical system performed by your local qualified electrician is the key.

Have it done once every couple of years to make sure all connections are tight in your panel.

Any broken or loose switches should or need to be replaced and have that done.

If you spend smaller portions of money having his maintenance done and it could save your money for the long term and we strongly advise it.

In addition you can also have whole home surge protection for your electrical panel.

This will help protect any of the equipment that is connected to the electrical system that may be at risk.

Is This Flickering A Fire Hazard?

The flickering itself is not a fire hazard but more of an annoyance than anything.

However the flickering is being caused for a reason. You need to get to the root of the problem because if you do have loose connections and arcing this can cause a fire.

We have seen switches that have melted the whole back of the switch because of a loose connection on the switch.

Once is arcing starts due to loose connection it’s almost impossible to stop it without replacing the device or the wiring associated with it.

Fires are something that you never want an electrical system obviously.

You can check yourself for warm spots on your electrical panel by touching it with the back of your hand. Additionally touch each wire on the outside of the panel to see if anything is warm or just drawing too much energy.

This is a sign of a problem somewhere in the system needs to be corrected as quickly as possible.

Is It Time To Upgrade My Electrical System?

Upgrading your electrical system is always great idea.

You can have your fuse is changed to breakers quite simply by your local electrician.

Newer breaker style panels have little or no problems.

Additionally you can look at getting some extra wires are extra circuits run in your house to get your light lighting circuit separated.

You should always separate your lighting circuits from your outlet circuit.
You may also have loose connections in your incoming lines from the street.

If these incoming lines are not properly connected this can cause additional issues.

In addition to that you could have corroded or loose wires inside of your meter base.

When you look at getting the upgrade done to your service panel you should also get the outside meter base changed as well.

Since these this equipment is subject to the weather this causes corrosion naturally inside of the meter base which can cause loose or arcing and also cause problems.

Remember that every single point there is a termination done in your electrical system is subject to corrosion.

This will reduce or eliminate the flickering of lights in your home.
