Disconnect Switch at Equipment Location

• A disconnect switch is required to be installed at the location of equipment such as a heat pump so that the equipment may be safely turned off when being serviced.
• Depending on the size of the equipment, a receptacle outlet may be used as the means of disconnect when the equipment is installed inside of a building.
• The specifics will depend on the equipment, the size and the location.
