Several items in the main lighting distribution box
Inside a distribution box are components like circuit breakers, earth leakage units, doorbells, and timers. The building's electrical power enters through the main feeding cable, which connects to the distribution board. It protects cables and devices from overload, disconnects circuits in the event of a fault and thus guarantees maximum safety. Acting as a central hub, a distribution box receives electricity from the main power. At its core, a distribution box, also known as a distribution board, panelboard, or fuse box, is a protective enclosure that houses all the electrical components that control and protect the circuits in a building. We'll chat about what each one does, where it shines, and then dive into how to choose the perfect box for your needs.
