electrical code for junction box A junction box provides a safe, code-compliant space for housing cable connections for outlets, switches, or splices. They prevent potential electrical shocks, and keep sparks from spreading to flammable surroundings. CNC machines are renowned for their precision in tool movement across multiple axes, each corresponding to a different direction of motion. Even basic CNC machines operate with three primary axes: X-axis: Horizontal movement, moving left or right. Y-axis: Forward and backward movement. Z-axis: Vertical movement, moving up and down.
