Standard Wiring Practices

Standard wiring practices is a basic guidelines for Electrical Engineer or Electrical Technician when involve in Electrical installation project.From the guideline,we can minimize the electrical safety issues,have a proper electrical route and more tidy installation and follow standard requirement.

Actually I had involved in many of Electrical installation projects and this standard wiring practices guide me  a lot  to get a best quality and perfection on my Electrical Installation project.Below I had listed some beneficial guideline when do you have a Electrical Wiring Installation.I hope it’s can give some basics information or guide to get a best result.

Electrical Conduit

What is a conduit?For an electrician work scope,conduit is a one of famous method for electrical cable route wiring in domestic or industrial sector.

A conduit is a channel or pipe that electrical cable are contained secure inside when do the electrical wiring.We can route the conduit at the surface or con-seal method.

The main purpose of conduit application are to providing a mechanical protection of electrical cable,easy for rewired or modification of circuit,flexibility and look tidy installation.Normally we can found several types material of conduit and it made for different application and condition such as PVC,Steel,Stainless Steel & Flexible.

Electrical Cable/Wire Sizing

This time i want shared about how to sizing the electrical cable.This topic is important because it’s involved with safety issue,cost and time line  for the electrical installation project.

Cable or wire sizing matter already discussed for a long time ago and it’s a hot topic for Electricians and Engineers.So i hope from this post,it can give a clear view and  understanding how to select current rating for wire,cable rating,voltage drop, and wire sizing for wiring project application

.From cable/wire sizing calculation we can estimate the proper size for cable to our wiring installation project.One thing that we need to prepared before cable or wire sizing  is several data or information about wiring project includes :

Types of electrical conduits

When we plan to do for electrical wiring,we need to use a conduit system to protect an electrical cable from damage due to mechanical or biological.It also make electrical wiring look nice and proper arrangement.

As an electrician,a knowledge about conduits is important to decide which types are suitable for our wiring application and structure.If we choose a wrong types,it can cause the serious damage,increase cost for material and also can reduce wiring life span.

An electrical conduit system is designed for electrical piping system used for wiring installation.It made electrical wiring more easy to installed and have a proper way. Electrical conduit may be made of metal, plastic,fiber, or fired resistance material. read more

Drawing for electrical installation

For electrical installation,the main factor to completed the task with quality and in time,we must make sure the detail and comprehensive drawing are provided.

These drawing is important to show in clear view about position of electrical equipment,access for electrical cable,switch and socket location and others important item.

The drawings scale are based upon the architect’s site plan of the building completed with electrical symbol to identified the electrical equipment for the real site to show the actual placed for installation works. read more

How to install lug for electric cable?

Cable termination is important when we install equipment,machine,induction motor,power supply distribution and many more.We use a cable lug to connect the electrical cable with terminal or busbar.

The right method to install cable lug is important to ensure the termination is perfect and tight to avoid sparking.It can cause the damage of cable or the equipment.This time i want share some information about how to install a lug for 240mm electric cable.

Please use the suitable crimping tools and correct cable lug  according electrical cable size.If not the crimping process will not perfect and it can cause a serious damage.Following video is one of example how to crimping cable lug for 240mm cable. read more

Temporary electrical supplies

When working at construction area or for temporary work space,the electrical supplies that we provided  can save our times and can speed up the working progress.Because the power tools and lighting or others equipment needed the power supply to completed the tasks.

We must ensure the temporary electrical supply that we install for construction works must in safe condition and comply with wiring regulation and suitable with working area hazards such as explosive or confined space.

The power supply wiring also must be of robust construction to cover electrical requirement and heavy duty to stand from environment such as rain,wind and sun also rough handling.It important to make the wiring condition is safe for our workers from electrical shock and others injuries. read more
