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.

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 :

Why current rating value is so important for cable/wire sizing?This time i want share some information about cable rating.It look like simple value but it give the big impact when we not do the proper sizing to the cable for our application.

If during cable sizing calculation not done in proper way,it can cause a serious damage for electric cable,equipment and human.It also can cause the waste of money when it over sizing and increase the budget for reworks.

That it current rating play a important role during cable sizing for electrical wiring job scopes.We can choose the right cable size read more

Types of electrical conduits

27/10/2011 by Leave a Comment

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

26/09/2011 by 3 Comments

The amount of light required for any of these industrial applications will depend upon the nature of the work carried out. The luminescence required for manufacturing operations is given in table below.

The size of lamp required can be calculated by considering the area to be lighted, the illuminance required,depreciation factor, and the beam factor of the particular projector to be employed.

The level of illuminance is important to ensure workers can perform their task in comfortable condition and not effected to their eyesight such as become blurred or if more serious can cause a blind. read more

Drawing for electrical installation

28/08/2011 by 3 Comments

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
