|---|---|
| 208Y/120 V | 833 A |
| 240 V | 722 A |
| 480Y/277 V | 361 A |
| 600Y/347 V | 289 A |
| 4.16 kV | 41.6 A |
| 12.47 kV | 13.9 A |
| 13.2 kV | 13.1 A |
| 13.8 kV | 12.6 A |
| 24.94 kV | 6.9 A |

Questions about used 300 kVA pad-mount transformers
How many amps is a 300 kVA transformer?
A 300 kVA three-phase transformer carries 361 A at 480 V, 833 A at 208 V and 289 A at 600 V at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 300,000 VA ÷ (1.732 × 480 V) = 361 A.
