So, I just come across your video and I literally just copied my question into google and came here out of curiosity , my question is pretty much exactly like yours with the expectation of the cooker instead it is just one cooker at 10.37kW rather than yours which is 2 x 6.5Kw. I'm just wondering where did you get your question from? Mine is from Level 3 Advanced Technical Diploma in Electrical Installation Unit 303 Worksheet 11 Question 3 *2024*.

Hi am just wondering when you add up the total I got 188.8 I don't understand how u got you're answer can you please show me thank you

​@craigrod5728 you have added the first 12.43. Only add everything that has been underlined. Using diversity, you only use 75% of 12.43, which is 9.3. When totaling up the maximum demand, we only include the 9.3, not the 12.43
