In the ceiling zone method of distribution, the usable floor area should be divided into zones each measuring:

9.3 sq m (100 sq ft) to 23 sq m (250 sq ft)

23 sq m (250 sq ft) to 56 sq m (600 sq ft)

23 sq m (250 sq ft) to 84 sq m (904 sq ft)

56 sq m (600 sq ft) to 84 sq m (904 sq ft)

56 sq m (600 sq ft) to 100 sq m (1,100 sq ft)

waldo31Option: B

correct answer : conduit should be used for each zone ranging from ≈23.2 m2 (250 ft2) to ≈55.7 m2 (600 ft2). This is based on ≈5.6 m2 (60 ft2) to ≈9.3 m2 (100 ft2) work areas and the diameter of the cable no larger than 6.3 mm (0.25 in). For larger zones ranging from ≈55.7 m2 (600 ft2) to ≈84 m2 (904 ft2), an ≈63 mm (2-1/2 trade size) conduit
