What size ground wire do I need for a 75 kva transformer?
For example, a 75-kVA transformer with a 480-volt primary and 208/120 volt, three-phase, four-wire secondary would have a maximum primary current of 90 amps and a maximum secondary current of 208 amps. The secondary conductors would be required to be 4/0 copper using 75 degrees Celsius insulated (or better) conductors.
What size breaker Do I need to feed a 75 kva transformer?
The rated current of the transformer can be used as the basis for a breaker. The rated current of a 3 phase, 75 kva transformer is 112 Amps, which is 25\% of the rated current of a 125 Amp breaker.
How many amps does a 75 kva transformer draw?
| Three Phase Transformers, Full Load Amperes (FLC) | ||
|---|---|---|
| KVA | 208V | 600V |
| 75 | 208 | 72 |
| 112.5 | 312 | 108 |
| 150 | 416 | 144 |
What size wire do I need for a transformer?
For Transformer, we should choose two types of cable such as the primary side and secondary side. The rating of the cable should be 150\% of the full load current. i.e if your transformer’s primary current is 450 Amps means, you should choose 450 *150\% = 675 Amps capacity size cable.
