An air conditioning disconnect (ACD) is a disconnect located between a loadcenter (distribution panel) and air conditioner. Eaton’s ACD product line provides an installer or repair personnel with a visible disconnecting means when performing maintenance. ACDs are also known as disconnects, pullouts or air conditioning switches. The most widely used application for ACDs is for residential and light commercial air conditioning units. An ACD is installed outdoors, in visible proximity to the air conditioner condensing unit. Metallic enclosures are galvanized steel and are installed in various locations. Nonmetallic enclosures are a plastic (polycarbonate) enclosure commonly used in coastal or salt-water areas.
