Are your electronics and appliances protected against power surges in the coming months? Learning how to install whole house surge protector is essential for Arizona homeowners during the monsoon season.
With power grid disruptions, severe weather concerns, and aging infrastructures on the rise, the risk of facing a power surge can be inevitable.
Whole house surge protectors help ensure all electronic devices and appliances in your house remain intact. If you live in a region vulnerable to storms or simply wish to ensure their longevity, investing in one should be a top priority.
Don’t leave your electronics vulnerable — keep reading below to learn more about installing surge protection devices.
What Happens During a Power Surge?
Every electrical system can be susceptible to voltage spikes and surges. This is especially true during monsoon season in Northern Arizona when lightning and power outages contribute to more surges than usual.
However, sudden power fluctuations don’t just stem from external forces — internal issues such as tripped circuits, short circuits, and power interruptions may also lead to surges that can potentially damage electronics in your home.
Power surges can happen when…
- Lightning strikes, which can potentially generate millions of volts of electrical power in a wire.
- There are downed power lines due to storms or other occurrences.
- The house’s electrical wiring is faulty.
- There are troublesome transformers in the electrical system.
- You have defective gadgets or appliances that consume more power than usual.
What Is a Whole House Surge Protector?
A whole-house surge protector is a device installed on the main electrical panel. Its primary function is to divert excessive voltage away from sensitive devices and appliances.
Imagine them as the protectors of your electrical systems at home. By diverting excess voltage to the grounding wire of your home electrical system, surge protectors help safeguard connected devices against potential damage or malfunction due to power surges.
Electrical fires can be avoided by taking measures to protect appliances and electrical devices from being damaged, such as protecting them against accidental overloading.
Why Use Surge Protection?
- Protects all electronics
- Provides constant protection
- Reduces the risk of electrical fires
- Saves money (protection and prevention are always more cost-efficient than replacing damaged electronics)
- Increases the resale value of your home

- Review safety measures: Only professionals and electricians with proper training experience should install whole-house surge protection devices. To ensure your safety, ask for professional help. Wear safety gear and comply with electrical safety regulations.
Step-by-Step Process of Whole House Surge Protector Installation
Always follow the instructions of the manufacturer when installing a surge protector. Consult a professional electrician if you are unsure about any step of the installation process.
- Shut off the power to your electrical panel by turning off the main breaker switch.
- Remove the panel cover and its screws.
- Use a non-contact voltage tester to verify that there is no electricity running to any of the circuit breakers in the panel.
- Choose a mounting location for the surge protector and install it according to the manufacturer’s instructions.
- Connect the ground and neutral wires from the surge protector to the appropriate terminals in the panel.
- Install a double-pole breaker next to the main breaker in the panel.
- Connect the live wires from the surge protector to the terminals of the double-pole breaker.
- Use wire cutters to trim the wires to a short and straight length.
- Use wire strippers and expose wires up to 5/8″ long. Check that the entire system surge protector has been exposed. Make any necessary adjustments to ensure that the wiring is even.
- Reassemble the panel cover and tighten the screws.
- Turn on the main breaker and the surge protector’s breaker.
- Test the surge protector by flipping the surge protector’s breaker to the off position and then back on. Verify the surge protector is working correctly, usually indicated by a green light or digital display.
- Once the surge protector is successfully installed and tested, replace the panel cover and secure it with screws.
- Turn on the main breaker to restore power to your electrical panel.
