Which of the following is a requirement for a facility housing electrical chargers for vehicles?

1. The chargers must operate on 110 volts

2. The chargers must be both listed and permitted for outdoor use

3. The chargers may be installed at any height

4. There is no need for specific listing requirements

The correct answer is: The chargers must be both listed and permitted for outdoor use

In order for electrical chargers for vehicles to be safely used in a facility, they must be both listed and permitted for outdoor use. This is crucial because chargers are often exposed to various weather conditions, including rain, snow, and extreme temperatures, which can pose safety risks if the equipment is not designed to withstand such environments. A product that is “listed” means it has been tested and meets specific safety standards set by a recognized testing laboratory, ensuring it is suitable for its intended use. The requirement for the chargers to be permitted underscores the importance of following local regulations and codes during installation. This often entails obtaining necessary permits prior to installation and ensuring all work complies with the National Electrical Code (NEC) and local amendments. By meeting both the listing and permitting requirements, facilities ensure safe operation and legal compliance, ultimately protecting users and property.
