What is the principle of relay protection for electrical boxes
A protective relay is an automatic device that detects abnormalities in an electrical circuit and closes its contacts. This action completes the circuit breaker 's trip coil circuit, causing the breaker to trip and disconnect the faulty section from the healthy circuit. Engineering use: Relays are used on feeders, transformers, buses, motors, generators, and transmission lines to protect equipment and improve system. A relay is an electrically operated switch. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof. Also principles of various protective relays and schemes including special protection. An electrical protection relay is an intermediate device that bridges the function of a current transformer or a similar fault-detecting device to one or more circuit breakers.

Color requirements for conduit in distribution boxes
Currently there are no color code requirements for raceways or cables in the National Electrical Code or other NFPA / UL standards for specific system applications in new construction installations. Most conduit manufacturers are already producing colored conduit products. All circuits, raceways, and conduits shall be color-coded, labeled, and sized to match the appropriate t Colo er drawings. If the conduit size is not given on the drawings, the conduit shall be sized in accordance with NEC based on the number of conductors enclosed plus a parity-sized. NEC Article 314 establishes requirements for the installation and use of electrical boxes, conduit bodies, fittings, and handhole enclosures. Unlike wire insulation, where colors like black, white, or green have clear and mandated meanings, EMT conduit color coding is.
