Using the standard calculation method, what is the total dryer load (line and neutral) for eight household dryers rated at 5.5 kW each?

Using the standard calculation method, what is the total dryer load (line and neutral) for eight household dryers rated at 5.5 kW each?

• A. 26,400 VA - Line; 18,480 VA - Neutral
• B. 28,600 VA - Line; 20,020 VA - Neutral
• C. 38,500 VA - Line; 26,950 VA - Neutral
• D. 44,000 VA - Line; 30,800 VA - Neutral

Answer: (A)

The main idea is that when clothes dryers are used in a dwelling, part of their power goes through the two hot legs (240 V) and part through the neutral (120 V) for controls and lighting. The standard calculation method assigns a portion of the total dryer load to the line conductors and a portion to the neutral. First, find the total dryer power: eight dryers × 5.5 kW each = 44 kW (or 44,000 VA). Then apply the standard split: line load is 60% of the total, neutral load is 42% of the total. This yields: - line load = 0.60 × 44,000 VA = 26,400 VA - neutral load = 0.42 × 44,000 VA = 18,480 VA These values match the given option.
