How many 20-amp 120-volt receptacles are shown along Column Line C?

To determine the number of 20-amp 120-volt receptacles along Column Line C, it is essential to reference the specific blueprint or drawing being analyzed. The receptacles are typically represented with symbols that indicate their location and specifications.

When reviewing the schematic provided in the blueprint, you would look for the series of receptacle symbols that align vertically with Column Line C. Each of these symbols represents a 20-amp 120-volt receptacle. By counting each symbol located along this particular line, one can ascertain the total number.

In this case, identifying six distinct receptacle symbols confirms that there are indeed six 20-amp 120-volt receptacles located along Column Line C. This aligns with the answer choice that indicates six, demonstrating accurate understanding of the blueprint layout and notation used in electrical design.
