High-voltage wiring, such as non-metallic (NM-B or Romex) cable, must be clamped and secured to the cabinet structure, especially where it passes through drilled holes in wooden framing members. Sharp edges must be avoided, and wires should be protected from abrasion to. The secondary wiring of the KYN28A high-voltage electric cabinet is rather complicated. The following is a detailed introduction for you:1. Welcome to the Principle Cabinet Design training module for the DCS800, ABB DC drives.

Cabinets are often the only way to route power to modern conveniences without opening walls, making this a common necessity in remodeling and new construction. Primary wiring: used to realize the transmission, distribution and control of electric energy, directly connected to the power supply and power equipment, responsible for the transmission and distribution of electric energy, and is the main circuit of the power system. For example, the power supply.
