No live wire in the distribution box
Be sure that the power distribution box has sufficient power provided to it. Long cable runs can result in a voltage drop, which can be solved by using a heavy gauge wire. Follow this guide for a clear and safe connection process: Before starting, always ensure the main power is turned off to avoid electrical shock. An exposed, energized wire creates a serious risk of fire and electrical shock and must be addressed immediately. The Main feeder cable to the Distribution Board should be able to handle the total power anticipated when all the sub circuits in the Distribution Board. A consumer unit (CU) also known as panel box, breaker box or fuse box is a type of a distribution board (aka electric panel, breaker panel, panelboard or main breaker-box or main service panel) which is used to distribute and fed the electric power to the sub-circuits and final sub-circuits. A distribution board (also known as panelboard, circuit breaker panel, breaker panel, circuit breaker, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit.
