Dwelling unit load calculation

Complete a standard-method dwelling calculation and explain each demand factor applied.

Work a single-family dwelling from general lighting through appliances to service size.

1. Enter the dwelling square footage and confirm the general lighting load that results.
2. Add small appliance and laundry branch circuits.
3. Add range, dryer, and HVAC loads and observe where demand factors apply.
4. Record the calculated service size and the largest single contributor.

State which single load in your calculation moved the service size the most, and what you would change to reduce it.
