Perform quick load calculations for single-phase and three-phase electrical systems, using p = v i pf, with 2.5 kw examples at 240 and 415 to 450 volts.
Explore the roles of distribution boards and main switchboards, detailing main breakers, isolators, miniature circuit breakers, busbars, and the three-phase versus single-phase feeds that power linked circuits.
Design light layout by calculating total fixtures, types, and loads to size the distribution board. Plan main cable and zones, and keep to ten fixtures or two kilowatts per circuit.
Continue with designing light layout by mapping wiring in three ways, filling load schedules for blue, red, and yellow phases, and calculating total loads for spotlights.
design the light layout by dividing fixtures into two groups on separate circuit breakers and use busbars to separate light points from power points.
Designing electrical layouts review covers light layout, load schedule, busbar connections, and circuit breakers with leakage sensitivity. It emphasizes gathering project details, consulting engineers, and obtaining client approval.
*Dear all, please note that am going to upgrade this course I will add 2 more projects to design which will help you to become more and more familiar with electrical layouts, hopefully in January 2022 I will finish the upgrading process, thank you a lot for appreciating.
Welcome all to the Electrical Wiring Course II. In this course I will teach you how to design Light layout, Power layout and DB schedule. In addition I will show you several layouts for several projects, so for sure you will expand your horizons. The project that we are going to design is a small dress shop. Once you understand how to design a small project then the big project will be the same procedures but with much more quantities. Section 3 is the main core for this course. Section 4 is the complement for section 3 and section 5 is the conclusion with General notes while section 1 is a quick revision and section 2 is a warm up before starting designing.
*I have kept some videos for free so you can evaluate and decide if the course is suitable for you.
If you don't know how to use AutoCAD no problem, you can work with me by printing out the attached plans and work by putting the note on the plan by your hand (prefer to use pencil).
Hint: This course is not for teaching you AutoCAD or how to use AutoCAD, instead I will teach you how to design the circuits in the Light layout and power layout, after that how to put it in the DB schedule.
If your goal is to understand electrical layouts for houses and buildings, I recommend you to subscribe in this course.
