Socket Outlet Circuit Load
Design load of a final electrical circuit supplying one or more socket-outlets.
A socket-outlet circuit load describes a group of outlet points connected to one final electrical circuit.
Because the actual load connected to individual outlets may vary, calculations consider the number of points, connected load, maximum demand power, and simultaneity or diversity factors.
The design current is used to select conductors and protective devices.
For specific applications, recommendations may be provided for a dedicated circuit, breaker rating and tripping characteristic, and the type of residual-current protection.
Final protection selection must take account of outlet purpose, operating conditions, and the requirements of applicable standards.
Design socket-circuit loads for sizing final socket-outlet circuits.
