For some couple of days now, I've been quite busy with an assignment I got from school. Yes! Despite the lockdown which resulted to the shutting down of schools, the school I attend still communicate with we the student via the Internet where we're been lectured and giving assessments. So, I got an assignment in of my courses, named 'Electrical Drafting And Design'. It's a course that basically deals with the design and flow of wiring diagrams, inclusive of power generation, and all the likes related to Electrical Power. The assignment questions were labelled in alphabet A to Z, with sub sections making it a total of thirty nine (39) questions. The most interesting part of the assignment question is what birth this post. It was the second question on the list.

We were asked to design the electrical services on the sketch of our individual homes and then use a well detailed symbol to indicate all components (i.e. electrical fittings/accessories) that are present in it. e.g. lighting fitting, sockets, switches, etc. Although the question here was incomplete, but further instructions later came from the lecturer that we should also make calculation on the amount of electricity that's been consumed in the building. So this means there will be three different steps to follow before achieving the final result.

First step would be to create the Electrical service layout, which is drawing the building plan of the apartment and indicating the electrical services that are present in it with its symbols. Then the second step would be to create a Legend, which is a chat that will state the name and rating of each electrical components that has been represented with symbols in the electrical service layout. And the third step would be to create a Load analysis table, which is where the calculations of the power consumed will be done.

So come with me, and let me put you through how I was able to achieve my results 😎. You know, since its something I'm going to be doing newly, I'm so excited to share with you how!

I started with drawing the building plan of my apartment. Yes, that's the building plan of my father's house in which I live in. This building plan is something I've been drawing way back form 2014. So drawing it again this time around was no struggle. In fact, I've been drawing it off hand since the past five (5) years, so I expect it to be easy too this time around. Although this section is the most times consuming section out of all the three sections. This section itself also requires some steps before achieving it final result. So, I took five (5) steps in achieving the result of this section.

Step 1:

This was where I made a thin outline of the building plan according to my own choice of sizes.

Step 2:

This is where I marked out the position that would serve as the the windows and doors. I also corrected a part of the outline that looked slant.

Step 3:

This is where I made a thick outline out of the thin out outline, that would serve as the walls.

Step 4&5:

This is where I added the windows and doors, and then I also added the electrical components that are present in the building.

With all the above steps, I was able to easily design the Electrical service layout. Now, this takes me to the next section which is the Legend.

A legend is a chart containing the details of all the symbols used in an individual diagram. It could be an electrical, mechanical, P&ID, or any other types of diagram.

This section is the most easiest section to achieve, and it didn't consume much time.

I immediately drew the chat and proceeded to the third section which is the Load analysis. This section requires some calculations. What this section basically contains are the; circuit type, description of electrical component, number of points, wattage per point, total wattage on all phases, current rating, MCB rating, and the cable size.

After drawing the table, and identify the circuit with its respective numbers of point and wattage. I then made use of a tool online in the calculation of the P.D (i.e. Potential Different).
