Surge Protection for
Home Level 1 EV Charging Stations

OVERVIEW

Today’s increased reliance on very sensitive electronics makes surge protection an important topic for Electric Vehicle (EV) Charging Systems. The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges. In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©.

This article discusses the application of surge protection for Level 1 EV Charging Station(s) at your home, in your garage or at the workplace.

EV Charging Levels

Go to Level 1 | Go to Level 2 | Go to Level 3

Level 1 EV Charging Station

Power Source : 120Vac Household Outlet

Level 1 EV Chargers are for residential home applications utilizing a standard 120Vac outlet for the power source. With up to 20 hours to charge time for a 124 mile trip, these chargers offer the convenience of a plug-in installation and portability in case that you move.

EV Level 1 SPD Protection Point : At The Main Distribution Panel

Per the NEC 2020, since your home is a dwelling unit as defined by Article 230.67, a UL1449 Listed SPD must be Installed at the incoming 120/240Vac main service panel. Shown below is an example using the M50-120T-A.

The M50-120T-A is installed via a 2-Pole 30A circuit breaker and will not only protect the Level 1 EV charging system but all circuits on the main service panel. This protector is what is referred to as a "Whole House Surge Protector".
