With what type of equipment should caps and receptacles be used?

Caps and receptacles are designed specifically for portable equipment to facilitate safe and efficient connections and disconnections of electrical devices. Portable equipment is often moved from one location to another, necessitating connection points where power can be easily accessed. Caps and receptacles provide a method to securely connect and disconnect the power supply without having to hard-wire the equipment, which is critical for flexibility and safety in operation.

This type of equipment often includes items such as portable heaters, coolers, or any devices that need to be frequently moved. The design of caps and receptacles ensures they are robust enough to handle the rigors of being often connected and disconnected, and they meet safety standards that reduce risks associated with electrical usage in various portable applications.

Other options, while involving different types of equipment, do not typically utilize caps and receptacles in the way portable equipment does. Permanent installations usually involve hard-wiring where caps and receptacles are not applicable. Heavy-duty machinery and high-capacity transformers generally require more permanent, industrial-grade connections to support their operational demands and safety requirements, further reinforcing why caps and receptacles are best suited for portable applications.
