An electrical service mast is the metal conduit that houses the power lines that connect your home to the electrical grid. This vertical pole runs from the utility lines down to the electric meter to safely bring electricity into your home.
Learn more about the importance of your electrical service mast, how to tell if it’s damaged and when it’s time to call the electrician.
Quick Takeaways
- An electrical service mast connects utility lines to the electrical system in your home.
- It provides structural support for incoming powerlines and protects service entrance wires from damage.
- In most cases, homeowners are responsible for the maintenance and upkeep of the mast.
- A damaged mast can quickly lead to safety risks, power issues and meter problems.
- Any damage or compromised service mast should quickly be inspected and repaired by a certified electrician.
What Is an Electrical Service Mast?
An electrical service mast is part of the framework that connects your home to public power lines. Many homeowners don’t even think about it until something happens.
What Does an Electrical Service Mast Do?
It acts like a sturdy support pole for the power lines that carry electricity into your home. It also houses the utility wires and keeps them at the proper height above the roof, ensuring they maintain the required safety clearances.
The service entrance conductors are the wires that carry electricity into your home. The mast also encases the wires in a durable metal conduit, keeping them protected from extreme weather, damage and wear.
Service Mast vs. Electrical Meter Can
Your electrical service mast and meter can are two important components of the electrical system that work together to safely power your home.
While the service mast is the metal pipe that supports the overhead wires, the electrical meter can is the enclosure that holds your electric meter inside. After electricity travels through your service mast, it enters the meter can.
These components are connected. This means that problems with one may affect the other. For example, a damaged service mast can put additional stress on the meter can. On the other hand, a deteriorated meter can create safety concerns and issues with your electrical service.
If you suspect your meter can is damaged, outdated or no longer meets your current electrical codes, don’t wait for the problem to get worse. Call a licensed electrician for professional electrical meter replacement services to keep your system up to code.
Who Is Responsible for an Electrical Service Mast?
Most of the time, the homeowner is responsible for the electrical service mast and the equipment attached to their home. This usually includes:
- The service mast
- Service entrance conductors
- The meter socket (meter can)
You are also responsible for any other components that connect your home’s electrical system to the utility company’s power lines.
The utility company is responsible for the meter connected to your home and the overhead service wires that run from the utility pole to your home’s service connection point.
Knowing where your responsibility ends, and the service company’s begins, can help avoid confusion, prevent delays and ensure that repairs are completed safely.
Signs Your Electrical Service Mast May Be Damaged
Your electrical service mast is exposed to all kinds of elements, including wind, rain and heat. If damaged, it can affect the safety and reliability of your electrical service over time. Here are some signs to look out for:
Leaning or bent mast – A leaning or bent mast means that it may have been damaged and can no longer properly support the utility wires.- Rust or corrosion – Rust can weaken the mast, increasing the risk of structural failure.
- Damaged weatherhead – The weatherhead is the cap at the top of the service mast where wires enter. If it is cracked or broken, moisture can damage the components.
- Loose attachments – Loose or damaged brackets, straps and fasteners can cause the mast to shift, creating a safety hazard.
- Visible wire damage – Fraying wires and exposed conductors can create electrical hazards and disrupt service.
- Water intrusion near your meter – Water stains, rust or moisture around your meter might be a sign that water is getting in because of a damaged service mast or weatherhead.
If you notice any of these signs, contact a professionally licensed electrician as soon as possible.
Can a Damaged Service Mast Affect Your Electrical Meter?
A damaged service mast not only affects incoming power lines, but your electrical meter and the connected equipment too. Because they work together to power your home, damage to one or the other can create problems for the whole system.
If your mast becomes bent, the stress caused by the weight and tension impacts the meter can. This can cause it to loosen or damage your electrical connections. As a consequence, you could experience inconsistent power (or complete power outages).
A damaged service mast is dangerous. Damaged wires, loose connections and water intrusions increase your risk of electrical shocks or fires. By addressing the damage quickly, you can protect your system and keep you and your property safe.
What Happens During a Service Mast Repair or Replacement?
If your service mast is damaged, it’s time to call a professional electrician who has extensive experience in service mast repair.
Here’s what happens once they arrive:
- Inspection – The electrician will inspect your mast (and the related components) to figure out the extent of the damage and whether it should be repaired or replaced.
- Utility coordination – Before repair work begins, your electrician will coordinate with your utility company to schedule shutdown and reconnection of your electrical service.
- Mast replacement or repair – After power is disconnected, your electrician will repair or replace your damaged mast. This could include installing a new mast or weatherhead, replacing damaged wiring and making sure everything is secure.
- Safety inspection – After repair or replacement is complete, they will check to make sure that all connections are properly secure and that your mast is supported.
- Power restoration – After work is approved and safety requirements are met, the utility company will restore power to your home.
Your electrician may perform a final inspection to ensure that everything is operating as it should and that your power is fully restored.
When Should You Call an Electrician?
If you think your mast may be damaged, do not touch it or any surrounding equipment. Here’s how to know if it’s time to call an electrician:
- After storm damage – Strong winds, hail and heavy rain can all bend the mast, damaging the weatherhead and wiring.
- If the mast is leaning – A leaning mast needs to be checked as soon as possible to prevent further stress on your electrical system.
- If you notice meter issues – Problems with your electrical meter may be related to a damaged service mast.
You should also call an electrician before making any electrical service upgrades. For example, if you’re installing major appliances or adding equipment (like an EV charger), an electrician can see if your existing mast is able to support these upgrades or if you need repairs or replacements to meet code requirements.
