Electrical enclosures are installed in widely varying locations – often your switchboard will be installed outdoors, vulnerable to heavy rain, high levels of humidity, corrosive minerals such as sea salt, dust and sun radiation. Another consideration that is sadly becoming more frequent is the threat of vandalism and sabotage. Carefully choosing an enclosure material is very important. Read on for a quick guide to your options.

Polycarbonate Enclosures

Polycarbonate has several benefits over the metallic options, notably its resistance to corrosion and acidic environments. Surprisingly, plastics often have good impact resistance and don’t easily dent and scratch. Its non-conductive nature eliminates the need for earth bonding straps to doors and covers.

Polycarbonate enclosures are generally used for smaller enclosures such as local control stations and marshalling boxes, and rarely used in large sizes due to cost.

Ideal applications: Small enclosures, local control stations, marshalling boxes, chemical environments .
