Question

A 600 ampere busway utilized at 600 amperes is set up in an industrial location. A 200 ampere busway, NOT in contact with combustible materials is tapped into it. What's the largest space the busway can run without supplying overcurrent protection for the 200 ampere busway?

a) 200 feet
b) 300 feet
c) 400 feet
d) 600 feet

Answer 1

The largest space the 200 ampere busway can run without supplying overcurrent protection is 600 feet.

Step-by-step explanation:

The largest space that the 200 ampere busway can run without supplying overcurrent protection is 600 feet.

In this scenario, the 600 ampere busway is set up in an industrial location and is tapped into by the 200 ampere busway, which is not in contact with combustible materials.

Since the 200 ampere busway is not in contact with combustible materials, it is not required to have overcurrent protection. Therefore, it can run the entire length of the 600 ampere busway, which is 600 feet.
