How do I choose a whole house surge protector?

Answered by Randy McIntyre

Choosing a whole house surge protector can be a daunting task, but with the right information, you can make an informed decision. Here are some factors to consider when selecting a surge protector for your home:

1. Surge Rating: The surge rating of a whole-house surge protector is crucial. It is recommended to choose a surge protector that can handle at least a 40,000-amp surge. This rating ensures that the surge protector can handle larger and more powerful surges, providing better protection for your home’s electrical system.

2. Thermal Fuses: Look for surge protectors that have thermal fuses. These fuses help protect the surge protector from overheating and potentially starting a fire. The thermal fuses automatically cut off the power supply if the temperature exceeds a certain limit, preventing any damage or danger.

3. Indicator Lights or Alarms: A good surge protector should have indicator lights or alarms that inform you when a device or the surge protector itself has taken a hit. This feature allows you to quickly identify if any equipment or appliances are at risk or if the surge protector needs to be replaced.

4. Installation: Consider the ease of installation when choosing a surge protector. While some surge protectors can be installed by homeowners, it is recommended to hire a licensed electrician for proper installation. The cost of installation should be factored into your budget when selecting a surge protector.

5. Capacity: Determine the capacity of the surge protector based on your home’s electrical system. Most homes have 200-amp service, so ensure the surge protector is compatible with this capacity. It is also important to consider the number of surge-protected outlets or circuits the surge protector can accommodate.

6. Brand Reputation: Look for reputable brands that have a track record of producing reliable surge protectors. Research customer reviews and ratings to get an idea of their performance and customer satisfaction. It is worth investing in a trusted brand to ensure the longevity and effectiveness of the surge protector.

7. Cost: Whole-house surge protectors can range in price, but for an average house with 200-amp service, you can expect to spend around $500, including the cost of an electrician’s labor for installation. Consider your budget and the level of protection you require when selecting a surge protector.

When choosing a whole house surge protector, consider factors such as surge rating, thermal fuses, indicator lights or alarms, ease of installation, capacity, brand reputation, and cost. By carefully evaluating these factors, you can select a surge protector that provides adequate protection for your home’s electrical system and sensitive devices. Remember to consult with a licensed electrician for proper installation and to ensure compliance with local electrical codes.
