Wiring 5A Switched Socket Outlet [5A Receptacle]
" The word “electromagnetic” which is used to characterize the phenomena produced by the conducting wires of the voltaic pile, … were those which M. Oersted discovered, exhibited by an electric current and a magnet. I have determined to use the word electrodynamic in order to unite under a common name all these phenomena, and particularly to designate those which I have observed between two voltaic conductors. It expresses their true character, that of being produced by electricity in motion: while the electric attractions and repulsions, which have been known for a long time, are electrostatic phenomena produced by the unequal distribution of electricity at rest in the bodies in which they are observed.

Wiring 5A Switched Socket Outlets [5A Receptacles]
Wiring of 5A Switched Socket outlet point is on the wane these days in Electrical Installation Work.
For maintaining the existing 5A Socket Outlet circuits, we are providing this information. Here we are considering wiring a 5A Socket Outlet [Receptacle] point for 50Hz, 230V AC Power Supply. Installation work described here is according to British Standards [ IEE Regulations and Practice ].Material Requirement
For Industrial applications, 1.5 mm2 [called as 1.5 mm squared] Cross sectioned double insulated Cu [Copper] Cables [Cu/PVC/PVC] are used for the Phase [Live ] and the Neutral cables.
For Residential applications, 1.0 mm2 Cross sectioned double insulated Cu [Copper] Cables [Cu/PVC/PVC] are commonly used for the Phase and the Neutral cables. Earth [Ground ]cable should be 2.5mm2 single insulated Cu[Copper] Cables [Cu/PVC] for both Industrial or Residential type of applications. Cable lengths for the above circuits will be such that voltage drop along the cables will be with in the approved limits of 10% of Supply Voltage.Accessory Requirement
PVC Box to install the 5A Socket outlet-01 nos
5A Switched Socket outlet-01 nos MCB 6A -01 nos [ from a Distribution Board already installed]Preparation
Install the socket outlet box at the required position.
Lay 3/4" PVC conduit from the Distribution Board to the receptacle position. The conduits can be embedded into the wall structure and or lay outside, clipped to the wall or structure. Instead of PVC conduits and switch boxes, GI conduits and switch boxes are being used for Industrial type of installations where you need protection for cables from physical damage. In some wooden structured buildings, the cables are installed inside panels without conduits being used.The Cables should be colour coded correctly for Phase[Live],Neutral and Earth.Method of Wiring -5A Socket Outlet Circuits
Make sure that the Power is isolated [ shut down] to the Distribution board or any circuit you will be working with.
Connect the Phase [L] wire to the outgoing side of a 6A or a 10A [Maximum] MCB from the Distribution Board [DB]. Draw the Phase wire to the socket outlet box and connect to terminal marked as L [Line] of the 5A receptacle. Connect the Neutral [N] wire to the Neutral Link provided in the DB and draw the wire to the receptacle and connect to the terminal marked as N [Neutral]. Connect the Earth [E] wire to the Earth link provided in the Distribution Board. Draw Earth wire to the receptacle and connect to the terminal marked as E [Earth]. It is good practice to number the Phase and the Neutral wires at the DB for easy identification as one circuit.Useful Links
