The U.S. Fire Administration wants to keep communities safe from fire and electric shock related to charging electric vehicles (EVs). There are two types of home charging, Level 1 and Level 2. Level 1 uses the charger included with the EV. These chargers are plugged into a standard 120-volt outlet. Level 2 charging uses a charger that is sold separately from the EV and allows for faster charging times. They are plugged into a 240-volt outlet. Read on for safety tips.

Before buying an EV, have a qualified electrician install:

• A new, dedicated circuit for your EV charging device. Older home wiring may not be suitable for use with EV supply equipment.
• A Level 2 charging device (if that is your preferred charging method).

When you charge an EV

• Follow manufacturer’s guidelines when charging your vehicle. Check with your local dealer if you need additional information.
• Purchase a charging device that is certified by a nationally recognized testing laboratory.
• Plug Level 1 EV chargers directly into an outlet designed to handle the amperage of the charging device. Never use a multiplug adapter or extension cord.
• Install a residual current device with the charging unit. It will turn off the power if a fault is detected and help prevent a fire.
• Place all charging device components out of reach of children when not in use.
• Maintain the components of your charging station according to the manufacturer’s maintenance guidelines. Signs of excessive wear may indicate a potential shock hazard. Never use an EV charger with obvious signs of damage.
• Cover the EV charging station outlet to stop water from entering. Check the manufacturer’s guidelines to make sure it is safe to charge your EV in wet conditions.
