The neutral or white wire is usually connected to the breaker box's neutral bus bar. Live (L) Wire Connection: In a distribution box setup, the incoming live wire (also known as phase or hot wire, denoted as L or Line) connects to the line terminal of the circuit breaker. The following introduces the specific installation methods from three aspects: preparations before installation, installation.

Metal electrical boxes must be grounded because they are conductive components that enclose energized wires and connections. Yes — if you're running AC mains power (like 120V or 240V) into a metal enclosure, grounding is absolutely required. This is a basic safety rule that helps protect against electric shock and potential fire hazards if a short circuit occurs. For field technicians, correctly handling the physical connection between the casing and grounding is a core aspect of complying with electrical acceptance specifications.

Grounding of the units: Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). In today's industrial automation and control systems, electrical control panel cabinets play a critical role in ensuring the safe and reliable operation of equipment. EMC is the ability of electronic equipment to operate without problems within an electromagnetic environment. The primary purpose is establishing a zero-voltage reference point for circuit operation and protecting sensitive electronic components. The following guidelines should be observed when grounding a cabinet: An unpainted earth reference plane or rail must be installed on the floor of the cabinet for the conventional reference potential.
