Electrical preventive maintenance is a crucial step in ensuring that your home or business doesn’t get damaged by poor electrical systems. There are several types of problems that can occur and impact the way your system operates. For example, your home may suffer from loose connectors that cause sparks. Without proper electrical preventive maintenance, your structure may burn down.

As a result, electrical preventive maintenance should be taken very seriously. Thankfully, there are several steps that you can take to ensure that your structure is not damaged. The following electrical preventive maintenance steps will also include the type of problem that it will fix. It will then give you a few steps to take to manage it.

Electrical Preventive Maintenance Checklist for 2017

These simple steps have been tested and confirmed by multiple electricians. They will showcase the best way to maintain your electrical system without causing it any damage. Remember to contact a professional to perform the actual steps for you. Your role in this job is to check for these problems, make sure that they are what you think, and then get a professional to help you.

Step One: Checking Loose Connections

One of the most common problems that plague electrical systems is loose connection. This situation occurs when wires are not connected properly to a system. Typically, about 30 percent of all electrical problems are caused by this situation. As a result, a good electrical preventive maintenance process should start by looking at all of your connections.

Do you notice any sparks popping up in your system? If you do, it is crucial to turn off your electricity right away and call a professional. Even if you don’t notice sparks, you may see that some connectors aren’t touching correctly or aren’t screwed down all the way. Calling a professional makes sure that these connections get fully repaired as soon as possible.

Step Two: Moisture in Your System

Obviously, electricity and water are a bad combination. When they are in each other’s company in your home, there’s a chance that your system could burn down very quickly. In fact, about 18 percent of all electrical problems occur because of too much moisture. That’s why it is essential to move to the next step in the electrical preventive maintenance procedure and check for water buildup.

This condensation typically occurs on the outside of a unit and should be pretty obvious. If you see any extra water on an electrical item, turn off your electricity and call a professional. There is probably some condition in your building that is letting in water. For example, excessive interior humidity may cause this moisture to build up and create severe damage to your electrical unit.

Step Three: Gauging Insulation Effectiveness

Next, it is important to check how well your electrical lines are insulated. This step in the electrical preventive maintenance process requires checking all of your lines and testing their insulation level. Any insulation that is frayed or falling apart must be replaced right away. Again, it is essential to contact a professional to do this step for you.

However, you may also be able to add some electrical tape on frayed insulation to help slow down the need for emergency electrical preventive maintenance. Never add electrical tape to wire if you see sparks or if it is completely frayed. Only add tape if you have turned off the electricity to the area. This way, no flashes will occur.

Step Four: Avoiding Overloading

Another important step in the electrical preventive maintenance process is checking your lines for an overload. Overloads occur if you are using too many of your electrical system at once. For example, running multiple outdoor lights (such as during Christmas) can strain your system and make it operate more poorly. Even worse, it can cause actual damage.

If your home suffers from multiple flipped or burned out circuit breakers, you have an overload somewhere. Check your wiring layout to see what area of the house the problem breaker manages. Then, you need to check all your plugins to see if you are running too many systems at once. It may then be necessary to get a better system installed in your home to match your electrical needs.

Step Five: Dirt in the System

One of the most essential, yet least understood, steps in the electrical preventive process is cleaning the system of dirt and other types of stains. This step requires inspecting all of the interior areas of your electrical system and ensuring that no dirt or stains are building up inside. Often, this requires vacuuming or cleaning the area with a rag.

Make sure to call professionals if the dirt gets too heavy. Excessive dust in the electrical system can cause the wires to overheat. When they overheat, they may ignite and allow a fire to spread. By cleaning out a system thoroughly, you can avoid this danger and also help your system run more efficiently.

Step Six: Protecting It from Lightning


Last, but not least, in our electrical preventive maintenance checklist is keeping your home safe from lightning. Lightning strikes are problematic because they can blow out a system or catch it on fire. Installing a lightning rod on top of your home can help keep this dangerous electricity away from your system.

You should also install new circuits and breakers in your system to avoid the danger of surges. These surges can happen when an area of your neighborhood gets struck by lightning. Surge protectors are also crucial because they will prevent damage caused by this excess electricity.


By now, you should have a pretty good idea of the steps you need to take in the electrical preventative maintenance process. Most of these procedures should be done by a professional. Calling a professional makes sure that you don’t cause any more damage.

Don’t hesitate to ask a professional for help in this situation. These pros can assess your needs and perform the electrical preventive measures mentioned here. More importantly, they can even take care of additional issues not discussed here to protect your home or business.
