To determine

The full-load current for a single-phase motor.

Expert Solution & Answer

Answer to Problem 1RQ

12 A

Explanation of Solution

Given:

The power of motor is 2 hp.

The voltage is 230 V.

Table 430.248 of the National Electric Code (NEC) is used to determine the full-load current of a single-phase motor.

The table 430.248 of the National Electric Code (NEC) is shown below:

Horsepower	115 V	200 V	208 V	230 V
1/6	4.4	2.5	2.4	2.2
1/4	5.8	3.3	3.2	2.9
3/4	7.2	4.1	4.0	3.6
1/2	9.8	5.6	5.4	4.9
¾	13.8	7.9	7.6	6.9
1	16	9.2	8.8	8.0
1 ½	20	11.5	11.0	10
2	24	13.8	13.2	12
3	34	19.6	18.7	17
5	56	32.2	30.8	28
7 ½	80	46.0	44.0	40
10	100	57.5	55.0	50

Here, the full-load current is in Ampere (A).

Thus, the full-load current for 2 hp and 230 V is 12 A.

Conclusion:

The full-load current for single-phase motor is 12 A.
