What is the minimum size raceway for the following feeder conductors is:

The motor branch circuit conductors must have a minimum capacity of 125 percent of motor full-load current to comply with Section 430-22. This results in a minimum conductor ampacity of (1.25 x 16.7) 20.9.

Explanation:

It is given that,

Let are the masses of two objects such that,

............(1)

Force between them,

Distance between masses, d = 19 cm = 0.19 m

The gravitational force between two masses is given by :

.............(2)

On solving equation (1) and (2),

Mass of heavier object,

Mass of lighter object,

Hence, this is the required solution.
