A switch disconnector combines the properties of a disconnector and a load switch, [1] so it provides the safety isolation function while being able to make and break nominal currents. Integrated disconnecting switch
Load-break/Load-make switches can switch normal system load currents; Isolators are off load disconnectors which are to be operated after Circuit Breakers, or else if the load current is very small; By voltage class: Low voltage (less than 1 kV AC) Medium voltage (1 kV AC through to approximately 75 kV AC) High voltage (75 kV to about 230 kV AC)
A distribution board (also known as panelboard, circuit breaker panel, breaker panel, 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 breaker for each circuit in a common enclosure.
Chassis or panel connectors permanently attached to a piece of equipment so users can connect a cable to a stationary device; PCB mount connectors soldered to a printed circuit board, providing a point for cable or wire attachment. [6]: 56 (e.g. pin headers, screw terminals, board-to-board connectors)
Grounding (earthing) of distribution circuits is a notable difference in practice between wiring systems of the United States and those of other regions. Since the early 1960s, wiring in new construction has required a separate grounding conductor used to bond (electrically connect) all normally non-current carrying parts of an electrical ...
The connector can also be disconnected under load. Like the IEC 62735, this connector was designed to replace the IEC connector used in computer power supplies so that they can be operated from 380–400 VDC instead. Introduced in January 2009, [22] it arrived before the competing IEC standard, however despite this it has not seen widespread use.

In an electrical power distribution system, a ring main unit (RMU) is a factory assembled, metal enclosed set of switchgear used at the load connection points of a ring-type distribution network. It includes in one unit two switches that can connect the load to either or both main conductors, and a fusible switch or circuit breaker and switch ...
