Hey how would you calculate the load for a basement along with the main floor? Would you take 75% of the area of the basement according to rule 8-110 C) and then use 8-200 1) a) i) (first 90 m^2) or use ii) (additional area of 90 m^2 or portion there of), would the basements flooring be considered as the first 90 m^2 or as an additional 90m^2 or portion thereof (if it was 133 m^2 and after taking 75% off it becomes 99.75 m^2) im just confused on whether it would fall under sub item i) 5000W per 90 m^2 or sub item ii) 1000W per 90 m^2 or portion thereof

Are you an electrical inspector or a sparky?

Why are you doing 40 amps for hot tub? Code says only water heater is taken at 100%

Thank you for your question. If you look at Rule 8-200 (1)(a)(v), you will see that any electric water heaters that are in a hot tub are included at 100%. This is why we take the Hot Tub at 100% as the heaters basically the major portion of the load.

Heater is the major load but is still not the full amp on the nameplate. If you take the heater amperage at 100% that is on the heater nameplate and then minus the heater amps off the hot tub full load amps then take 25% of the rest of the hot tub it reduces greatly the amount of amps towards the load calc. This is how it was explained by the csa interpreter and inspectors as a possibility of doing it.

@k6lgI can agree with that logic and it does make sense. You also mention that the way you were shown is a "possibility" of how to do it so now we get into the different interpretations. (Don't you love the Code Book!) Worst case in my example is you are adding a few amps extra to the calculation and lets face it, todays residential services are fairly over sized already.
