Why Install Whole-Home Surge Protection?
Many homeowners are unaware that the National Electrical Code now requires a whole-home surge protector. The National Fire Protection Association added that requirement with the 2020 update. Does that mean you have to update? No, you’re not legally bound to. That said, if you ever perform electrical upgrades that require a permit, you will be. Upgrading now future-proofs your house and also makes it a lot safer.
Direct and indirect lightning strikes are certainly a concern, but they aren’t the only ones. A blown transformer is another example of an external surge that can damage your home. You can also experience damaging internal surges. This includes surges from air conditioners, heat pumps, standby generators, and other appliances with powerful motors.
There are two main types of house surge protector devices: Type 1 and Type 2. The NEC requires a Type 2 surge protection device. We also recommend using Type 3 devices, such as surge protector strips. Our electricians install Type 2 devices inside a home at the panel, and they provide protection against the most common issues. Those include indirect lightning strikes and internal surges and spikes.
Homeowners have the option of adding both Type 1 and Type 2 protection. Type 1 devices function outside of the home. The goal of these is to provide protection between the grid and the house’s electrical system. They provide the best protection from direct lightning strikes and anomalous grid power. Those events aren’t common but can be incredibly destructive.
There are many benefits to installing a house surge protector:
- Prevent electrical fires
- Home insurance discounts
- Avoid expensive repair costs
- Protection against lightning strikes
- Safeguard valuable electronic devices
