These three terms - Fuse Box, Switchboard, and Distribution Board - are often used interchangeably, but they have slightly different meanings, especially when you delve into the specifics.
A Fuse Box typically refers to an older type of electrical service panel that was common up until the late 20th century. These boxes used fuses to protect electrical circuits. If the electrical current was too high, a fuse would 'blow' or burn out, effectively safeguarding the building from potential electrical fires.
The term Switchboard is commonly used to describe the panel where the circuit breakers or fuses are located within a residential setting. This is the panel you'd visit to reset a tripped circuit breaker or replace a blown fuse.
On the other hand, a Distribution Board, while performing similar functions to a switchboard, is a term more commonly used in industrial or commercial settings. It refers to a larger panel that distributes electricity to multiple circuits, which could include several switchboards.
In essence, while all three terms are related and pertain to the distribution and control of electricity within a property, they represent different components or iterations of an electrical system. If you're unsure about the electrical system in your building, don't hesitate to seek advice from a professional electrician.
