Basically wiring types differs based on the load and the condition it is exposed to.
In case of domestic use it is mainly classified based on the voltage level of the appliances used in house, low voltage level(like phone, doorbell) and high voltage level.
Electrical wires are rated as per the size and their ampere rating.
Wiring Type Based on Load:
1.Triplex Wire
2.Main Feeder Wire
3.Single Strand Wires
4.Multi-Strand Wires
5. Panel Feed wires, etc.
Each has its own purpose.
Apart from this there are certain stranded(Like colour codes, wiring safety codes) maintained while wiring in domestic level.

Methods of Electrical Wiring Systems w.r.t Taking Connection
Wiring (a process of connecting various accessories for distribution of electrical energy from supplier’s meter board to home appliances such as lamps, fans and other domestic appliances is known as Electrical Wiring) can be done using two methods which are
Joint box system or Tee systemLoop – in system
They are discussed as follows:
Joint Box or Tee or Jointing System
In this method of wiring, connections to appliances are made through joints. These joints are made in joint boxes by means of suitable connectors or joints cutouts. This method of wiring doesn’t consume too much cables size.
You might think because this method of wiring doesn’t require too much cable it is therefore cheaper. It is of course but the money you saved from buying cables will be used in buying joint boxes, thus equation is balanced. This method is suitable for temporary installations and it is cheap.
Loop-in or Looping System
This method of wiring is universally used in wiring. Lamps and other appliances are connected in parallel so that each of the appliances can be controlled individually. When a connection is required at a light or switch, the feed conductor is looped in by bringing it directly to the terminal and then carrying it forward again to the next point to be fed.
The switch and light feeds are carried round the circuit in a series of loops from one point to another until the last on the circuit is reached. The phase or line conductors are looped either in switchboard or box and neutrals are looped either in switchboard or from light or fan. Line or phase should never be looped from light or fan.
Advantages of Loop-In Method of Wiring
It doesn’t require joint boxes and so money is savedIn loop – in systems, no joint is concealed beneath floors or in roof spaces.Fault location is made easy as the points are made only at outlets so that they are accessible.
Disadvantages of Loop-In Method of Wiring
Length of wire or cables required is more and voltage drop and copper losses are therefore moreLooping – in switches and lamp holders is usually difficult.
