What are important points we should keep in mind while designing an electrical drawing?

The following steps that should be taken into consideration while designing the electrical network .

1.first we should know the incoming voltage.

2.exact location of the electrical incoming feeders and range.

maintenance free and easily under stable to non-technical persons.

3.Give more importance while selecting the cables,circuit breakers,surge arrestors ,connectors and earthing system .

4.while designing the designer should know what kind of loads.

5.all the protective devices should be capable of withstanding the short circuit or over load currents . 

1- You should be sure that mistakes are not allowed on electrical design.

2- Be sure for the calculation of loads, safe factor, enough space between electrical elements.

3- The cost should dos not pass the panel budget.

In doing electrical design we should always consider the electrical standards like

IEC or NEC or other electrical codes. Although there are clients specifications or 

requests it should be verify if its applicable on electrical standards.

1.Electrical Design must maintain accuracy and country standard.2. Symbols, notations etc must be clearly mentioned.3. It should be simple and eaay to understand.

As per bsi standard we have to draw electrical drwngs

I. If we want to Design A Electrical System we need to Fulfill the Following Credentials.

 

   a. It must be easy to operate , Maintenance free.

   b.Fulfill the International and Local Safety Standards.

   c. Keep in mind Local Govt and Electricity Rules and regulations.

   d.It must be safe to operate to the personnel.

   e.FMCG,Pharma and Food Processing differs the electrical Design.  

1. giving exact dimension to drawing

2.lines should be drawing according to the need of project .

3. in small place we should to accommodate more and more drawing.

1. Electrical design is for the Safety of the system first  to consider.

2. All electrical works must followed as per government standards for electrical design.

 

 

1.Avoiding re-work after execution

2.consider future extensions.

3.failure mode case analysis help to prevent future problems

4.consider power saving equipments e.t.c

  We must be under the global system of electric power

A) It must be easy to obtain maintenance free. B) All electrical works must be followed as per gov standard for electrical design. C) fulfill the international and local safety standard.
