An Overview of Significant Changes to the 2020 National Electrical Code for Dwellings

Services supplying all dwelling units require surge protection devices (SPDs) located within the equipment or adjacent to it. Both Type 1 SPDs and Type 2 SPDs are acceptable. This requirement includes multi-family services as well. There is an exception allowing an SPD to be installed at each next downstream device if installation at the service is not practical.

In multi-family units, install SPDs at each dwelling’s service disconnect.

This requirement extends to include both new construction and replacement equipment, such as service changes or upgrades.
