Distribution box disconnection measures

Home / Distribution box disconnection measures

During the normal operation of the distribution box, manual or automatic switches can be used to switch on and off the circuit. This is one of a series of Best Practice Guides produced by Electrical Safety First* in association with leading industry bodies for the benefit of electrical contractors and installers, and their customers. Automatic disconnection of supply is an interruption of one or more of the line conductors effected by the automatic operation of a protective device in the event of a fault (Source: IEC 61140-2016). A disconnect box is a localized manual shutoff switch designed to isolate power to a fixed appliance, such as an air conditioning unit, heat pump, or pool equipment. This device is installed near the equipment to provide a convenient, observable point of power interruption for maintenance or.
