Electrical Socket-outlet and Switches:

INTRODUCTION: 

Sockets was categorized under power circuit,which supply electrical energy to the connected load. It should be directly connect from distribution fuse board for safety and proper energy delivering. While Switches are under lightning circuit, normally they can be loop together with common supply. But do not make all your light with common supply, during fault total darkness will arrive in the whole resident,so divide

A-13Amp Socket-Outlet B-15Amp Socket-Outlet C-1Gang-1way Switch D-2Gang-1way Switch E-3Gang-1way Switch F-4Gang-1way Switch  Socket outlets:  13AMP SOCKET: is the power outlet, it used 2.5mm2 as a load wire from main distribution panel. 15AMP SOCKET: is the air condition or machine power outlet it need 4mm2 pure copper cable, it must have direct source from distribution fuse board.  Switches:  1.  ­­­­­­­­1Gang 1-way switch : This switch has one gang and 1way this means it control single point of light in off or on state, whit out any alternative.  2Gang 1-way Switch: This has ability to control more than one point of light at the different time .for instant it can be used to control point of light  in  the  corridor  and other gang to control security light.  3Gang 1-way  switch : It allow 3 points of light to be control at different time, it  is applicable  for ability  which has a lot of security light to reduce load in one gang only. 4Gang 1-way switch: it just an additional advantage over the 3gang , this will reduce connecting much lighting point on single gang. 1Gang ,2-way switch: this is 2way switch, that give user chance to be able to control single point of light at the different position for  instance in your bedroom, you can  connect at the opposite opening of the door, and another one at your bed, during entering  you canon the light after clamming your bed, you can turn the light off ,which out returning to the first switch. procedure of connecting it is as follow:                          Water heater switch: It was rated 20A.  Intermediate Switch: is a switch which always installed at the middle of 2way switches, for instants in an hotel or industries in a long corridor you can either switch on or off of the light point at any position .this eliminate returning  back to switch on or off.

The above ring circuit must have 4.0mm2 as load cable.  ELECTRICAL POWER CIRCUITS  Introduction: power circuit consists of socket out let with high power rating which include:13A,15A,20A,32A that feed power consume devices such as Air conditioner,bathroom heater,press iron, washing machine and warm room heater. As an electrician,there is measure to be taken for standard electrical wiring. Firstly, size of cable is very important each power circuit has its cable rating. All power circuit must be connected independently to distribution board for safe and accurate delivery of power supply. Only few13A socket outlets can be tapped together, but15A and above,it must be connected to distribution board MCB independently from 20A to above. For 13A circuits,use 2-5mm2,15A use 4mm2 while cooker unit use 6mm2,do not loop high power circuit is against IEE regulation. Also for piping work,layout separate piping connection for power circuit, during the pulling of cable you can use correct means for lubricating the high cable power rating,for easing pulling, due to long distance. There is an important precautions, as an electrician to apply,like at the natural terminals, make sure you high it accurately,also at each socket outlet terminals make sure high it very well to avoid electrical surges which is enemy for home appliances, so avoiding it will safe our appliances from burning. It is advisable to assign separate distribution board for power circuit, this will give you chance of utilizing small power rating generator for your light point. Ring circuit must be assign to 30A MCB and load wire must be pure copper. Ring circuit 80HP. 4HP 60KW. 30KW https://en.m.Wikipedia. com/  must be install according to the following guidelines: The floor area must not passed100m2,only13A socket outlet was permitted to use in ring circuit,But 15A and above, must be install independently Also, it advisable not connect ring circuit close to distribution board, since closer conductor carry less impedance,which leads to inequality share of the load. As stated earlier 2.5mm2 cable rating is OK. It is permitted to connect spurs, that is socket outlet attached to ring circuit, it connected using normal single cable not like ring circuit which use double cable through each socket outlet. Have your ever asked yourself, is their any problem or effects? Let us look very well, if there is partially fault in ring circuit, it will not prevent it from working. This is dangerous,because if your Nabor house start burning without your knowledge, you too can be affected, like wise in ring circuit if one path of cable have fault, one day,the cable path can also affected. Do you know the risk of this fault? The user is not aware of it. Also a result of the above mentioned problem of ring circuit, Radial circuit is more advantageous because;if there is fault along the cable length of the socket outlet, no more supply Until fault is rectified. Relax ring circuit has advantage of delivering more power than radial circuit.This can power high load safely and also this will lead to less power loss that is voltage drop due to high diameter of cable. At terminals of each terminal of socket out let must be high very well to avoid surge. Sockets are categorized under power supply in electrical wiring system. Care must be taking, concern its load wire do not under rate it.  For 13A, used 2.5mm2.For 15A, use 4mm2.while for Cooker Control Unit use 6.0mm2, for safety quality power deliver
