Disconnect Boxes
What is an AC Disconnect Box?
AC disconnect boxes are also referred to as disconnect switches or simply a disconnect. National Electric Code 440 requires a box to “locate the disconnecting means within sight of, and readily accessible from, the air-conditioning or refrigerating equipment.” AC units are dangerous to work on, and servicing them often requires our technicians to shut off power.
Having an accessible way to shut off the AC unit is very important for safety and proper service. For this reason, a disconnect is typically installed near the outdoor AC unit before the system is put into operation.
This allows technicians to quickly disconnect power when performing repairs, maintenance, or other work on the equipment. Since these electrical components are installed outdoors, they are exposed to rain, humidity, heat, and other elements that can cause rust and corrosion over time.
Regular inspection can help identify problems before they become more serious. EzE Air Solutions recommends checking for rust, corrosion, water damage, loose connections, or damaged wiring. A damaged disconnect switch can create a safety concern or prevent technicians from safely servicing your AC system. If you notice visible damage or believe your AC disconnect needs attention, contact EzE Air Solutions to have it inspected by a qualified HVAC professional.
