What is Disconnect?
A disconnect, also known as a disconnect switch or safety switch, is a device used to isolate electrical circuits by breaking the connection between the power source and electrical equipment. This ensures that technicians or electricians can safely perform maintenance, repairs, or installations without the risk of electric shock.
In residential and commercial electrical systems, disconnects are commonly used for HVAC units, water heaters, or larger machinery. For example, a rooftop air conditioning unit will typically have a nearby disconnect box to cut power during servicing. Proper use of disconnects enhances both safety and code compliance, especially in high-voltage or high-demand environments.
