I am trying to calculate the demand Load requirements for a 1900 SF single family home.

I've gotten to the point where the "Fastened-in-place appliances" are calculated, well, their rating. However, I see no mentioned where to place the garage door opener. After all, the motor for this equipment is fastened to the frame of the roof of the garage.

I will like to know where to add this equipment because if it needs to go under this "appliances" matrix, it will be my fourth unit and according to the NEC (220.17) I must multiply the total volt-amperes by 75% when calculating for four or more units.

Can anyone help?

Thanks.
