Pros and Cons of Whole House Surge Protector

They Provide Peace of Mind

In addition to potentially costly damage to your home’s electrical system, a power surge can destroy electronics worth thousands of dollars, as we discussed above. What’s worse is that most homeowner’s insurance policies don’t provide coverage for damage brought on by electrical surges.

To avoid this pricey scenario entirely, however, you should install a whole-home surge protector. This will give you the utmost assurance that both your home and your wallet are safe.

What Are the Cons?

Here are a few drawbacks of whole-house surge protection.

Cost of Installation

The cost of installing surge protectors is in addition to the price of the device itself. The surge protector must be connected to your home’s electrical panel during this professional installation. This form of installation ensures that your whole home surge protector protects your whole home from surge events.

They Don’t Stop All Surges

Whole-house surge protectors are actually made to let through surges that don’t reach a certain voltage. Every whole-home SPD comes with a specified “VPR” (voltage protection rating), which determines the maximum voltage the surge protector will let through to your home’s electrical system.

However, a whole-home surge protector with a high VPR might allow in smaller surges that can still gradually harm electrical appliances.

Our suggestion? Ensure you’re installing a whole-home surge protector with a low VPR but also “layer” your home’s surge protection.

Get a whole-home SPD, for instance, with a VPR no higher than 600V, but also make sure that your electrical appliances are protected with point-of-use surge protectors or built-in surge protector outlets. In this manner, the second layer of surge protection directs any excess voltage that bypasses the whole-home SPD.

Types of Surge Protectors

There are three types of surge protectors on the market. When selecting the finest one for your house, you must first identify the surge protection device type.

Type 1. External Power Surges

The Type 1 devices offer the best defense against low-powered surges and external sources. They additionally protect against low-power surges. Surges of this kind are rarely harmful.

Surge protectors are installed at the base of the electrical service meter before the main breaker box. Because this is known as the “line side,” only safe amounts of electricity may enter your home.

The power must be turned off in the house before installing Type 1 surge protection. Professional electricians are hired to complete the installation, which can significantly raise costs.

Type 2. Internal Power Surges

The most widely used surge protectors are type 2 whole-house models, which are the ones we feature in this article. Both the main panel and a sub panel can accommodate their installation. Anybody with some experience in electrical work and knowledge of DIY projects can install them. However, we advise hiring a qualified electrician to complete the installation for you.

One circuit in an electrical panel or every circuit can be protected by type 2 surge devices. This is why it is handy to have a knowledgeable electrician.

New homes should be equipped with a Type 1 or Type 2 device, according to the National Fire Protection Association (NFPA). If you are replacing your service panel, it must include one of these devices.

Type 3. Internal Power Surges

Wall outlet and power strip surge protectors are examples of type 3 point-of-use surge protectors. They are a well-liked and affordable method of shielding your electronics from power surges. It plugs into any household outlet and typically has 4-6 additional outlets. This is a practical method for safeguarding electronics like TVs, computers, or gaming consoles.

Surge arresters are the name given to these gadgets. Surge protectors can prevent the majority of damage and absorb excess power. They aren’t completely successful, though.

How Long Will a Whole House Surge Protector Last?

The lifespan of a whole house surge protector depends on how often and how badly power surges occur in your area. Some top companies warranty their products for 5 years while lasting over 10 years is common. But because of their wear and tear, these gadgets must occasionally be replaced.

However, from our research, a whole-house surge protector in areas with frequent power surges or outages can last for 2 to 3 years.

Therefore, a qualified electrician might suggest that you have extra surge protectors installed in your home’s electrical panel. The price of these additional surge protectors will be the same as the initial protector.

The decision to live without the additional peace of mind and rely solely on strip surge protectors is yours.
