What is the MINIMUM number of outside building terminal pedestals required to serve a single story office, or office warehouse structure that has ten 18.3 m x 24 m (60 ft x 80 ft) units and the total building length is 183 m (600 ft)?

Each unit has dimensions of 18.3 m x 24 m, so the total area of the ten units is (18.3 m x 24 m) x 10 = 4392 m². The length of the building is 183 m. The National Electrical Code recommends one terminal pedestal for every 90 m² of outdoor area. Therefore, the minimum number of pedestals required is (4392 m² / 90 m²) + 1 (for the building exterior) = 50.8, rounded up to 51. However, it is common for builders to use two pedestals for redundancy and easier access, so the best answer is B) Two.
