The minimum allowable ampacity for the feeder conductors in Problem 9 is _ A.

The ampacity of a 6 AWG RHW Al conductor in a room temperature of 47 °C is _ A.

An autotransformer rated less than 1000 V shall have the overcurrent protection set at not more than _% of the full-load input current of the transformer.

There are _ conductor strands in 1/0 AWG THHN Al wire.

The short-circuit protection for the motor in Problem 5, using an ITCB, normally may not exceed _ A.

The maximum size ITCB allowed for a 120/240 V, 1Ø, 3-wire feeder that powers a 3 HP, 230 V, 1Ø motor and two 1HP, 230 V, 1Ø motors is _ A.

If the nameplate of the motor in Problem 5 reads 28 A, _ A is the value used to determine the overload protection.

_ is ambient temperature.
