For eight 5.5 kW dryers using the standard method, the line-to-neutral loads are respectively 26,400 VA and 18,480 VA. What is the approximate ratio of line to neutral loads?

For eight 5.5 kW dryers using the standard method, the line-to-neutral loads are respectively 26,400 VA and 18,480 VA. What is the approximate ratio of line to neutral loads?

• A. 1.20
• B. 1.43
• C. 1.60
• D. 1.80

Answer: (B)

The concept is to compare the line-to-neutral loads by forming a ratio between the two VA values given. Take the larger line-to-neutral load, 26,400 VA, and divide by the smaller one, 18,480 VA. 26,400 ÷ 18,480 ≈ 1.4286, which rounds to about 1.43. So the approximate ratio of line to neutral loads is 1.43.
