Load calculations and Article 220
Article 220 is the general-load chapter: floor area, small-appliance circuits, and demand. The free problems print every volt-ampere figure the step needs so you can practice the arithmetic without a copied table.
- Read the stem for the VA per square foot and the VA per small-appliance circuit. Those numbers are part of the question. They are a drill, not a claim that your codebook’s table prints the same value.
- Do the general lighting total first, then add the circuits the stem lists, then apply only the demand the stem actually describes. Inventing a demand factor is how a clean setup becomes the wrong choice.
- This topic is the core of the calculations portion. After the untimed set feels mechanical, sit the calculations mock and keep the same order of operations under the clock.
Dwelling VA totals and demand, using the figures printed in the problem.
