• You have presented very well about XLPE and PVC cables. You have clearly mentioned the differences between the two cables. Also your presentation about single core double core and three core was quite simple. You mentioned about peak hours and off peak hours in your country. You were very thoughtful and articulate on this point. (1.9)

• You have calculated the electrical loads used in your home and figured out their wattage. All the load calculations are identified and calculated and it is presented very well. The separate calculations of each load look better. (2)

• You have presented your calculations according to the HT meter reading. All the power wise units and costs are well documented by you. The clarity of the sheet excel you mentioned was quite interesting and transparent. (3)

• You have solved your post according to the data at point D. Here the product of power factor and total voltage and current is mentioned. Power is equal to the product of voltage current and pf. It would be great if you could give some details on this calculation. Which should make your mathematical solution clearer. Your calculations are correct here though. (2.1)
