Current Transformer Cabinets and Terminal Enclosures
Current transformer (CT) cabinets house current transformers that are used to convert a primary current into a secondary current, usually reducing a large current into a smaller current for measurement and protection. Due to the large currents involved, it is important that CT cabinets provide the necessary protection and prevent possible electric shock. CT cabinets must meet the safety standards of Underwriters Laboratories (UL) and National Electrical Manufacturers Association (NEMA). The standards set for CT cabinets is UL Type 1 and NEMA Type 3R. Most CT cabinets are made of aluminum, galvanized steel or stainless steel.
Terminal enclosures are similar to junction boxes in that they house one or more wiring connections. Terminal enclosures are designed to protect the connections from environmental conditions and accidental contact. They are typically available with 3 or 4 wire configurations in sizes up to 440 A. They are constructed to meet UL Type 1, NEMA Type 3R and UL 1773 standards. UL 1773 is specific to terminal enclosures. Most terminal enclosures are made of aluminum or steel.
