You're permitted to use wiring channels if they're made of a flame-retardant insulating material. If you're working with back-connected control panels, you must provide access doors or swing out panels that swing about a vertical axis. Multiple-device control panels must have terminal blocks or attachment plugs and receptacles to terminate and connect all outgoing control conductors.

Two of the phases are also connected to the transformer to power the logic. The start and stop buttons are at the left of the box (note: normally these are mounted elsewhere, and a separate layout drawing would be needed).

When electricity was originally used for practical purposes, it was used for communication in the form of the electric telegraph and the telephone. Petroleum and paraffin lamps were still lighting homes until the late 1800s, when Thomas Edison developed the light bulb.

If the screen is to be connected then make it off in the same way as for coaxial cable with a soldered pigtail and a sleeve.

A highly disturbing device (variable speed drive, frequency converter, etc.) will have less radiation in the panel if it is “encapsulated” in a small, electromagnetically sealed, unpainted metal enclosure.

Transformers may be fitted with turret tags suitable for soldering and printed circuit board assemblies may have solder pins.

From an electrical standpoint, industrial machine equipment and tools - from drill presses to multi-motored automatic machines - can present special fire and shock hazards.

A receptacle outlet is one in which one or more receptacles are installed for the purpose of attaching “plug and cord-connected” type devices, and a lighting outlet is one intended for a direct-wired connection to a lamp holder, luminaire (lighting fixture) or ceiling fan.
