Steps to Consider Power Wiring

Steps to Consider Power Wiring Points : steps to consider power wiring When deciding on the system of wiring to use for a particular installation or section of an installation, many factors have to be taken into account by the engineer. These can be listed as follows:

Whether the system is to be installed during the construction subject to mechanical damage, moisture, fumes, weather, high temperature, or other adverse conditions)
Amount of money to be spent
Time available
Appearance
Safety
Load to be taken
Voltage to be employed (i.e. extra low, or medium).
Type of building
Ease with which extensions and alternations can be made
Length of time installation is required to last.
Whether the building is subject to frequent changes of tenancy

Frequently, a combination of several wiring systems may be used to advantage in one installation e.g. in an industrial installation, the main and sub-main cables would probably be armoured and run in ducts. The power and light wiring in the factory would be carried out in heavy gauge conduit, whereas in an office block adjoining, this would be done by sheathed cables buried in plaster in the walls and concealed conduit run in the cement floor and ceilings.

Each of the above wiring systems are described in this section with advice as to where each can be best used taking all the factors into account, and the relative advantages and disadvantages of each.
