A weatherproof enclosure for an outdoor EV charger is protection that shields the charging equipment from rain, snow, dust, and the elements. There are two parts to this: EV chargers intended for outdoor use are themselves built with weatherproof, outdoor-rated housings, and in some cases an additional enclosure or cabinet can provide extra protection. Understanding how outdoor charger protection works helps you keep your equipment safe and reliable.
Here is what a weatherproof enclosure for an outdoor EV charger is.
Outdoor-rated chargers are built weatherproof
The most important point is that an EV charger installed outdoors should be an outdoor-rated unit, meaning its housing is designed to withstand the weather. These chargers are built to handle rain, snow, humidity, and temperature swings, with sealed enclosures that keep moisture out of the electronics. So the first line of defense is simply using a charger rated for outdoor installation.
Charger enclosures carry ratings that indicate their level of protection against the elements. An electrician selects a charger with the appropriate rating for an outdoor location.
What a weatherproof enclosure adds
Beyond the charger’s own weatherproof housing, an additional enclosure or protective cabinet can be used to provide extra shielding. This might be used to:
- Add protection in harsh conditions or exposed locations
- Shield the charger and its connector from direct weather
- Provide a mounting solution, such as a pedestal, where there is no suitable wall
- Add security in some situations
An enclosure is not always necessary, since outdoor-rated chargers are built to handle the weather, but it can add protection and convenience in certain installations.
Why outdoor protection matters
An EV charger is an electrical device exposed to the elements when installed outside. Without proper weatherproofing, moisture could reach the electronics, causing damage or safety issues. Proper outdoor rating and, where appropriate, an enclosure protect the equipment, maintain reliable charging, and keep the installation safe. This is why using correctly rated equipment is essential for an outdoor charger.
Other outdoor installation considerations
A weatherproof charger or enclosure is part of a proper outdoor installation, which also includes:
- The correct outdoor-rated circuit and connections
- GFCI protection, as required for the installation
- Proper mounting and placement, protected from physical damage where possible
- Correct cable management for the outdoor environment
An electrician handles all of these so the outdoor charger is safe and reliable in all weather.
A weatherproof enclosure for an outdoor EV charger refers to the protection that keeps the equipment safe from the elements. Chargers intended for outdoor use are built with weatherproof, outdoor-rated housings, and an additional enclosure or cabinet can provide extra protection or a mounting solution in certain installations. Using correctly rated equipment, along with a proper outdoor-rated circuit and GFCI protection, keeps an outdoor charger safe and reliable. A licensed electrician sets this up correctly.
