A weatherproof electrical junction box is an outdoor electrical box that is designed with added strength to withstand harsh outdoor conditions. 

It is designed specifically to withstand elements, including high and low humidity, rain, snow, wind, etc. Weatherproof electrical boxes are made from a variety of materials, including plastic, aluminum, and galvanized steel. 

The different materials allow for flexibility for the manufacture and a wide price range. To understand the differences in weatherproof electrical boxes, it is first necessary to understand what they are. 

The electric current in a circuit board goes through a series of copper wires, which are protected by what is known as an electro-foam insulation material which is then sealed. 

While a protective fuse or circuit breaker is generally provided for each individual circuit in a shared enclosure, they also divide power into multiple sub-circuits while also providing a means to detect outages and provide emergency assistance when needed. In order to store all the electric wires, junction boxes are used. 

There are many manufacturers that offer a full line of weatherproof electrical boxes, along with a wide range of accessories to complete your installation.
