Question Description

I’m studying for my Engineering class and need an explanation.

the house should be from 1 floor +2 rooms 1 toilet 1 living room 1 small kitchen

less then 10% similarity

introduction should be (200 words ) in house wiring in general

report body's should explain every small concoction and calculation in words and numbers in details and what are the things that effect the current, voltage , and power. three phase & single phases connection total power 13 Kw to 16 Kw. At lest tow body's to reach (1100 words including the numbers and calculation )

conclusion should be a summery about the report and the aim of it ( 200 words )

assignment guide liens are in the below attachment

AimTo provide the knowledge and design skills to develop a residential electrical wiring system as per regulation standards.
Learning OutcomeSelection and Design of cable sizes in compliance with IEE Wiring Regulations (AM8, AM9).    

Summary of the task

Electrical house wiring regulations are necessary to decide the conductor size of cable for 220-240 V electrical supply under different weather conditions. First, it is necessary to understand the significance of power-flow study to fix the voltage-limits from the source to the load point. Then based on 17th wiring regulations/16th IEE wiring regulations/ National wiring regulations, design the ampere carrying capacity of wires used in a house. Further, recommend the safe and cost effective earthing technique to avoid from electric shock.

Furthermore, the Course Work report should contain as per the marking scheme given in the page-3. The length of the main body text of the technical report should be between 1500 and 2000 words. Main Heading: Arial Bold, size 12; Sub Heading: Arial Bold, size 11; Body text: Arial, size 11; Line spacing – 1.5; Paragraphs – Justify.

Students are instructed to read, understand the following points to complete the given Electrical Wiring- Design task for the house:

  1. Conduct a power-flow study distribution radial network having 04/05 nodes to understand voltage variation from source to load by assuming load data and line data.
  2. Collect the electrical load capacity for all appliances of a sample residential house.
  3. Calculate  the conductor design current (Ib), nominal current (In), perspective current (Iz), short circuit current (Isc) and % voltage drop for 1-phase, AC supply voltage with following parameters:
  4. Standard insulated conductors for group of 2/3/4/5/6 and clip to a surface.
  5. Cable operating under 03 different ambient temperature conditions.
  6. Refer the Appendix (Page-2) to tabulate the results obtained.
  7. Sketch and compare the different type of earthing systems used in Oman/Any other opted country for studies and recommend cost effective suitable earthing system.
  8. Calculate the earth fault loop impedance for home selected and justify its need.
