Surge Protection for
Home Level 2 EV Charging Stations

OVERVIEW

Today’s increased reliance on very sensitive electronics makes surge protection an important topic for Electric Vehicle (EV) Charging Systems and Electrical Vehicle Supply Equipment (EVSE). 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 2 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 2 EV Charging Station

Power Source : 240Vac Household Outlet

Level 2 EV Chargers are for residential home applications utilizing a 240Vac outlet for the power source. With up to 8 hours to charge time for a 124 mile trip, these chargers are faster than EV Level 1 Chargers and are hardwired to the main service panel.

EV Level 2 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.

Main Panel with M50

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