What is a frame ground?

A frame ground, also known as a chassis ground, is a reference point in an electrical system where the metal frame of a device or equipment is connected to the earth or a common ground. This connection helps to ensure safety by preventing electrical shock and reducing noise in electronic signals. It provides a pathway for fault currents to safely dissipate, protecting both the equipment and users from electrical hazards. Frame grounding is commonly used in various applications, including vehicles, appliances, and industrial machinery.
