  • What was the earliest model of electrical distribution box

    What was the earliest model of electrical distribution box

    The first electrical system for general use was established in Godalming, England, in 1881. The concept of a central distribution point for electricity can be traced back to the early 1880s when Thomas Edison and his team pioneered direct current (DC) power systems. In these early setups, a series of fuses and switches were used to control the flow of electricity, but they were far from. 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.
