Calculate the load center length for a 208V, four-wire, three-phase branch circuit with the following fixed noncontinuous loads:
60A at 45' from the source
40A at 60' from the source
30A at 75' from the source
25A at 100' from the source
a. 60.40'
b. 63.55'
c. 71.72'
d. 85.21
b. 63.55'
60A x 45' = 2,700
40A x 60' = 2,400
30A x 75' = 2,250
25A x 100' = 2,500
Find the sum of the results, and divide it by the sum of the individual loads:
2,700 + 2,500 + 2,250 + 2,500 = 9,850
60A + 40A + 30A + 25A = 155A
9,850 รท 155A = 63.55'
