Figure $230\mathrm{.}271$

Wire connected to the motor must have the correct ampacity according to the $75$ column. However, inside the conduit between the panel and the wireway ampacity corrections are made, as usual, in the $90$ column. The specifications require that separate equipment grounding conductors be installed in each raceway. The engineer who wrote the specs means that a metal raceway can't be used as the only EGC. But remember that only one EGC must be installed in each conduit. The small wireway is located near the motor location.

Refer to the drawing shown below to answer questions that refer to this figure.Refer to Figure $230\mathrm{.}271.$ Between the panel and the wireway, the minimum size circuit conductors for Motor #$4$ are $$ AWG. Count the number of circuit conductors in the conduit and determine ampacity inside the conduit from the $90^($@$)$ column.

Select one:

a$.12$

b$.8$

d$.6$
