What is junction box and control panel

Junction Box and Control Panel

A junction box is not a special type of box but rather any standard electrical box used to enclose wire splices. Junction boxes must be installed where they are always accessible; never install a junction box in a concealed wall or ceiling space where the box cannot be accessed in the future.

You ought not to attach a grounding wire on to the metal enclosure (Junction Box) if you're simply victimization it as a pull purpose and you're otherwise grounding it using continuous runs of EMT. 250.148 from the NEC for grounding conductors to boxes only applies where conductors are spliced within a box, or terminated on equipment within or supported by a box.

Installing Junction Boxes. When upgrading the wiring for a room, you may find it necessary to tap into a wire to add a branch circuit for light or outlet. You'll need a junction box if you cannot create the connections within AN existing electrical box.

Control Panel

Electrical Control Panels are available in different shapes and sizes and require specialized individual handling. The machines operate at 600 V or less and comprise power moreover as management circuits.

Their purpose is to manage the industrial plant instrumentality and supply one collective base of operations for the engineer to manage the producing method. ICPs are available as either open or closed type panels depending upon use. Old type electrical control panels are consists of push buttons and analog instruments.

They are found in factories to watch and management machines or production lines and in places like atomic energy plants, ships, aircraft, and mainframe computers. The panel may offer electricity to control any associated initiating device, notification appliance, control, transmitter, or relay. There area unit four basic sorts of panels: coded panels, typical panels, available panels, and multiplex systems. Electrical control panels are important in all the electrical circuit as a protective barrier.
