How do you calculate cable size for a KW motor?
The cable size is equal to the 1.5 times of the full load current of the motor/load. Hence the cable rating formula can be written as, Cable size = 1.5 x Full Load Current.
How do I choose cable size from KW?
To decide 95 Sq.mm cable, cable selection condition should be checked.
- Cable derating Amp (187 Amp) is higher than full load current of load (139 Amp) = O.K.
- Cable voltage Drop (2.2%) is less than defined voltage drop (5%) = O.K.
- Number of cable runs (1) ≥ (139A / 187A = 0.78) = O.K.
Which cable is used for 50 hp motor?
What size wire do I need for a 50 hp motor?
| Motor HP | NEMA amps | Phase Wires (AWG) |
|---|---|---|
| 40 | 52 | 4 |
| 50 | 65 | 4 |
| 60 | 77 | 2 |
| 75 | 96 | 2 |
How do I calculate motor cable size?
Size of Cable for Branch circuit which has Single Motor connection is 125% of Motor Full Load Current Capacity. Example: what is the minimum rating in amperes for Cables supplying 1 No of 5 hp, 415-volt, 3-phase motor at 0.8 Power Factor. Full-load currents for 5 hp = 7Amp. Min Capacity of Cable= (7X125%) =8.75 Amp.
How to calculate the cable size for a 5.5kW motor?
From our cable size calculator, the full load current of the 5.5kW motor is 10A. Cable size = 1.5 x 10 =15 A. Hence, the required cable shall able to carry minimum 15A current. Look at the Cable current rating Chart, 2.5Sqmm copper has the ability to carry 18 Amps, hence 2.5sqmm is suitable for 5.5kW/7.5HP motor.
