Electrical Enclosures

Piedmont Plastics carries polycarbonate for electrical enclosure cases. Polycarbonate does not conduct electricity and is less expensive than most metals.


An electrical enclosure is a case used to mount electrical or electronic components like switches, knobs, and displays. Electrical enclosures are designed to prevent electrical shock to equipment users and protect the contents from the elements. Electrical enclosures can be made from carbon steel, stainless steel, fiberglass, and polycarbonate. The use of polycarbonate in electrical enclosures is becoming more popular due to its durability and cost-effectiveness.

Polycarbonate has many benefits over metal for use in electrical enclosures. For one, polycarbonate does not conduct electricity. This makes it a great material for situations where there are concerns about electrical arcing or shorting. Polycarbonate’s electrical resistance also makes it ideal for installations where electronics will be located near water. Plastics, in general, are less expensive than most metals, making polycarbonate a cost-saving alternative to steel or most other common materials used to make enclosures. Unlike metal, polycarbonate enclosures don’t need any additional coating to protect the structure from the elements. Even uncoated, polycarbonate electrical enclosures won’t rust or corrode. Lastly, polycarbonate helps to keep the overall weight of the unit down, lowering shipping costs.
