Thread: What is this device on the breaker?

This was on the furnace breaker in this morning's condo. Is it a security device of some kind?

Generally furnaces breaker requires a dedicated circuit of their own to supply the electrical power requirements for the blower and thermostatic controls. A Furnaces breaker can easily install a lock to lock when cb works on the equipment.




Thank you.

lockout tagout device so repairman can safely work on item. See them in industrial plants all the time.

Breaker lockout. Usually when you see one, you will not see a service disconnect at the appliance that it serves. Code usually requires either a service disconnect at or within sight of the appliance , or, a breaker lockout device. It's a safety device to protect service personnel. You should have seen a little hole on the breaker lockout where the service tech could put a small padlock.

The use of a lockout at the breaker is okay for basically all appliances except air-conditioning or refrigerating equipment, which requires the disconnect to be within sight from readily accessible from the equipment - within 50 feet straightline sight - nothing is permitted to block the view from the equipment to the disconnect.
