## How many amps is a 75 KVA 208y transformer?

75 KVA is equal to 75,000 VA. (K= 1,000) The full value in VA, 75,000 divided by 1.732 = 43,302, which is then divided by the Voltage 208V = 208.2 Amperes.

## How many amps is a 1.5 KVA transformer good for?

60 amperes

If your transformer is rated at 1.5 kVA, and you want to operate it at 25 volts, multiply 1.5 by 1,000 to get 1,500 and then divide 1,500 by 25 to get 60. Your transformer will allow you to run it with up to 60 amperes of current.

**How much load can a 75 kva transformer handle?**

Three Phase Transformer

KVA | 208V | 2400V |
---|---|---|

60 | 167 | 14.5 |

75 | 208 | 18.1 |

100 | 278 | 24.1 |

112 | 313 | 27.1 |

### What size wire do I need for a 75 kVA transformer?

This transformer is rated 75,000 VA (75 kVA × 1,000 = 75,000). The primary side current will be 90 amperes (A) (75,000 ÷ 480 ÷ 1.732 = 90.2 = 90). This transformer will be sized for continuous loads; therefore, the conductors must have an ampacity of at least 113A (90 × 125% = 112.5 = 113).

### What size breaker do I need for 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.

**Can you hang a 75 kVA transformer?**

The 75 kVA transformers you reference can be hung in the open on walls, columns or structures and are not required to be readily accessible but they cannot be installed in hollow spaces of buildings, 450.13(B).

## How far does a transformer have to be from a wall?

12 in. to 18 in.

Transformers should be located at least 12 in. to 18 in. away from walls and other obstructions that might prevent free circulation of air through and around each unit, unless the unit is designed for wall mounting and installed per the manufacturer.
