The neutral wire may or may not be cut depending on the switch style. So if the upstream device is a circuit breaker, the local disconnect will need to be fused in order to have an installation that meets ul requirements (and hence, nec requirements). This fuse, with a lower rating than the fuse for a ring man, allows an electrical supply using one feed cable to a socket to be taken off a ring main.

When installing or maintaining equipment on the circuit, or the circuit itself, the switch provides a method to manually shut off the power. This switch is available in different forms. Switch disconnectors combine the properties of (load) switches and disconnectors.

The switch symbol typically refers to a single pole switch which is most commonly wall mounted and found in all areas of the home. Fuses are devices containing a small piece of special wire that melts when the intensity of the current flowing through it for a certain period of time exceeds a set value, thus protecting the rest of the electrical circuit overloads. Symbol can also be used for circuit breackers, isolators a.s.o.

Fused switch disconnectors protect workers performing maintenance on part of an electrical circuit, as well as preventing damage to the circuit itself. Fused disconnect switch the symbol is a combination of a fuse and disconnect switch with the switch in the open position. To meet this need, a disconnect or safety switch is absolutely critical.
