Whole Home Surge Protection Now Required by National Electric Code - What Are Your Options?

The new 2020 National Electric Code (NEC) includes a wide range of updates. But one of the more substantial changes is the addition of a new Section 230.67, which requires the installation of a surge-protective device (SPD) for all dwelling unit service entrances. 

Under this new requirement, all systems installed in new construction homes, as well as any replaced electrical equipment and systems, must incorporate Type 1 or Type 2 SPDs. 

Both types of SPDs are permanently connected and protect against external and internal surges. However, a Type 1 SPD may be installed inside or outside the home, while a Type 2 SPD is installed in or next to the breaker box.

As their name suggests, SPDs protect your home against power surges. A power surge is a temporary overvoltage event that can damage your electrical devices. Power surges commonly cause the failure of electrical equipment.

The National Electrical Manufacturers Association estimated that the average home has $15,000 worth of equipment that can be damaged by surges. It’s also estimated that 80% of surges are caused by internal sources. 

Examples of internal sources are: large appliances turning on / off, faulty wiring or loose connections, overloaded circuits, short circuits or ground faults, and power recovery. 

Examples of external sources are: lightning, damage to power lines, and utility power grid switching. 

Like anything else, not all SPDs are created equally. Some better protect your home than others. So, how do you know which SPD is right for your home?
