Frequently Asked Questions
Not exactly. A 'fuse box' traditionally contains fuses, while a 'switch box' contains switches (like circuit breakers). In modern homes, the 'consumer unit' (UK) or 'breaker box' (US) serves both functions, so the terms are often used loosely.
Yes, though 'network switch' is the active device. The physical enclosure housing it might be called a 'switch cabinet' or 'rack'. 'Switch box' is sometimes used informally for small, standalone units.
Always assume it is live unless you have personally isolated the power at the main supply. Only qualified persons should work inside one.
