I need code help

[SHA-BAM]

O.k. this may be a dumb question but I am stuck on this question and just don't understand.....

The living area for a single living dwelling has been determined and it requires a basic load of 6kW.
The house has the following loads....
Dryer of 3.5kW
Electric space heating of 3.5kW
Air cond. of 1.5kW
hot tub heater of 3kW
Kiln of 3.5kW


Am I wrong to add all the loads at 100%?
My answer is 21 but the real answer is 20.250....... what am I doing wrong?

See rule 8-200(1)(a)(vi)
Basic load=6000w
AC=1500w
Tub heater=3000w
ESH=3500w
Dryer and kiln together=6000w+(1000*.25)=6250w
6000+1500+3000+3500+6250=20250W

You would add the dryer and kiln together, if they are over 1500w up to 6000w the demand is at 100%, anything over that would be at a demand of 25%, so 6000+250=6250w
