Explanation:

Types of Electrical Wiring Systems

The types of internal wiring usually used are

Cleat wiring

Wooden casing and capping wiring

CTS or TRS or PVC sheath wiring

Lead sheathed or metal sheathed wiring

Conduit wiring

There are additional types of conduit wiring according to Pipes installation (Where steel and PVC pipes are used for wiring connection and installation).

Cleat wiring system installation is easy and simple.

Customization can be easily done in this wiring system e.g. alteration and addition.

Inspection is easy and simple.

Disadvantages of Cleat Wiring

Appearance is not so good.

Cleat wiring can’t be use for permanent use because, Sag may be occur after sometime of the usage.

In this wiring system, the cables and wiring is in open air, therefore, oil, Steam, humidity, smoke, rain, chemical and acidic effect may damage the cables and wires.

it is not lasting wire system because of the weather effect , risk of fire and wear & tear.

it can be only used on 250/440 Volts on low temperature.

There is always a risk of fire and electric shock.

it can’t be used in important and sensitive location and places.

It is not lasting, reliable and sustainable wiring system.

2.   Capping wiring
