The smallest branch circuit conductor size permitted in a given installation is 2/0 AWG. Which of the following lists that size among the options?

The smallest branch circuit conductor size permitted in a given installation is 2/0 AWG. Which of the following lists that size among the options?

• A. 250 kcmil
• B. 2/0
• C. 1
• D. 3/0

Answer: (B)

In electrical sizing, conductor sizes can be written in AWG (with notations like 2/0, 3/0, etc.) or in kcmil (thousand circular mils). The question tells you the smallest allowed branch circuit conductor size is 2/0 AWG, so you’re looking for the option that shows that exact designation. The option that reads 2/0 matches the specified size. The other options use a different notation or a different, larger size (for example, 3/0 AWG is a different size, and 250 kcmil represents a much larger conductor). So the correct listing is the one that reads 2/0.
