SKETCHING ELECTRICAL LAYOUT PLAN

A WebQuest for 4th Year High School (Drafting IV-TLE)
Designed by: Ernie L. Balbuena – ernie_balbuena@yahoo.com

Technical drawing, also known as drafting or draughting, is the technique of creating accurate representations of objects for architecture and engineering drawings. A skilled practitioner of the art is known as a draftsman or draftsperson (or draughtsman, draughtsperson in the UK).

In this activity, the students will be able to sketch and layout a house floor plan and incorporate the electrical section of the plan.


TASK:

The grouped is task to sketch a house floor plan and draw the electrical layout diagram by connecting a lamp which will be controlled in three different locations using one 4-way switch and two 3-way switches that will be placed in the kitchen, in the bedroom and in the lounge.

In this activity, the following guide questions will help the group to finish the project.

1. What are the fundamentals rules in sketching a house floor plan?
2. Identify different schematic symbols used electricity.

3. How would you connect 4-way switch and 3-switches to control a load?
4. How will scale your house floor plan dimensions to fit in your sketching paper?
5. What are the guidelines in making a legend in the drawing?
6. How would a house floor plan be approved?
7. What is the work of the electrical building inspector?


THE PROCESS:

You will work together in groups of three. Each member in your team will have a specific job to perform. You are given one week to finish the Webquest.

1. One student is to be the Draftsman’s. He is responsible in sketching the house floor plan and other job pertinent to drafting.

2. The other student on the team is the Electrical Engineer. He is responsible for the operating work loads of the plan and approved the plan based on the standards.

3. Another student will be the Electrical Inspector of the place. He is responsible for the approval of the plan and electrical permit.

Keep in mind that each member on the team must coordinate his/her activities with the other 2 students and they will need to work together in group.


CONCLUSION:


There are two primary benefits that the teacher hopes the students will gain from this WebQuest. One benefit is that you will acquire a more thorough understanding of water pollution and how it can affect us. Second benefit is that the teacher hopes that the students will be able to carry out own research using the Internet to create a Photostory and a brochure. Finally, the teacher hopes that the students will be better able to work in cooperative groups in solving problems.
