In this video, I'll show you the complete wiring diagram of a home distribution board (DB). You'll learn how to connect the main circuit breaker (MCB), residual current device (RCD), and individual circuit breakers for lighting, sockets, and appliances. It is responsible for distributing electricity throughout a building, ensuring that each circuit receives the proper amount of power.

This guide gives you clear spacing rules, how to measure them in the field, and quick reference tables for each common conduit type—EMT, RMC, IMC, FMC, LFMC, LFNC, ENT, and PVC—based on the 2023 National Electrical Code® (NEC). Getting raceway support right keeps your installation safe, code-compliant, and inspector-friendly. Overfilling conduits causes excessive heat buildup, difficult wire pulling, and potential insulation damage, while oversizing wastes money and installation space. A conduit body is a removable-cover section of a conduit system that provides access at junctions or termination points. When installing insulated conductors of 4 AWG or larger, the minimum dimensions of pull or junction boxes installed in a raceway or cable run must comply with 314.
