There are 4 main types of electrical lockout devices, each with its specific application:
Circuit Breaker or MCB (Miniature Circuit Breaker) Lockout Device – this lockout device uses a snap or clamp mechanism to lock circuit breakers in the OFF position. It is then secured with a suitable padlock to prevent unauthorized removal.
Plug Lockout Device – this lockout device encloses the prong-end of a plug, making it impossible to be plugged into a power source. It’s made with durable, lightweight, dielectric thermoplastic bodies.
Pendant Lockout Device – is a lockout bag capable of locking out large electrical connectors, oddly-shaped plugs, crane pendant controls, elevator controllers, and more. It has a flexible, durable, and high-quality rip-stop polyester/nylon bag, secured by multiple padlocks or hasps.
Electrical Panel Lockout Device – is a lockout device used to lock electrical panel buttons and switches that do not have a built-in lockout feature. It has removable push-button and rotary switch covers, with transparent bases and coverings that allow nameplates and labels to be seen.
