How to connect the ground wire of the AC-side cabinet

Here's how to connect your ground wire to the electrical panel: Locate the ground bus bar inside the panel. Cables equipped with a screen must be connected to ground. The grounding distance and impedance should be as short and low as possible. This pathway prevents metal casings of appliances and tools from becoming energized with hazardous voltage during an internal. System grounding Ground or earth provides a common return path for electric current in an electric circuit. Grounding is needed for electric safety and it also creates a reference point. Some of the usual termination ways for ground wires include: Grounding Lug: The fitting features a compression section that receives the incoming cable. Grounding Bar: This refers to a bar that can connect many. All of the externally exposed metal parts in your pin cab should be "grounded", meaning that the metal parts are all electrically connected to the Earth ground wire in your AC power plug. This includes the leg bolts, side rails, front lockbar, coin door, and plunger housing.
