Residential Surge Protection Solutions
There are three core types of SPDs: Type 1, Type 2, and Type 3. Until January 1, 2023, the National Electrical Code (NEC) did not require Type 2 SPDs in homes. As a result, most homes built before that date lack surge protection. The NEC does not require Type 1 SPDs, and many households also lack adequate Type 3 protection.
If you’re unsure whether you have enough protection or any protection at all, we recommend that you schedule an inspection. Homeowners often ask if they must or should upgrade. You don’t legally have to upgrade unless a permit requires it. However, we strongly recommend that you upgrade, as it protects you against fires and other electrical hazards.
The NEC requires Type 2 SPDs to operate on the load side of the electrical panel. These devices protect against many external surges, such as indirect lightning, as well as internal surges and spikes from appliances like air conditioners and generators.
People often wonder if they need to upgrade their panel. The answer is not necessarily. However, if the panel is old or inadequate, we generally recommend upgrading it.
Type 1 SPDs operate on the service side of the panel, positioning themselves between the panel and the incoming power from the grid. This setup enhances protection against direct lightning strikes and unusual grid power. While these events are rare, they can have destructive consequences when they do happen.
A Type 3 SPD offers local protection. A common example is a surge protector strip that many households use for their computing and home entertainment equipment. You can also upgrade your outlets with integrated Type 3 SPDs, USB charging ports, and other features by contacting us.
