#### How many amps can a 300 kva transformer handle?

What is a 500 kva transformer?

The 500kVA transformer plays the role of converting electrical energy in the power distribution system and is usually installed in the end-use area for residential lighting, industrial production, etc.

## How do I know what size cable I need for my 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.

How do you calculate the maximum load of a transformer?

How to calculate transformer load capacity

1. Obtain the transformer kVA rating.
3. Rearrange the kVA equation to leave the current on one side and our parameters on the other. Resulting in: I = 1000 ⋅ kVA V I= \frac{1000 \ \cdot \ \text{kVA}}{V} I=V1000 ⋅ kVA.
4. Plug in the data and solve!

### How many amps can a 200 kVA transformer handle?

So, with this formula, we could manipulate it to get the number of amperes that a 200kVA transformer would be able to handle. The final answer will be 288.68 amperes if it is a 3-phase transformer and 833.33 amperes if it is a single-phase transformer.

How do I choose a transformer size?

How to Size a Transformer

1. Transformer size is determined by the kVA of the load.
2. Load voltage, or secondary voltage, is the voltage needed to operate the load.
3. Line voltage, or primary voltage, is the voltage from the source.
4. Single-Phase has two lines of AC power.

#### How do I work out what size transformer I need?

Since you know kVA = V * l / 1,000, we can solve for V to get V = kVA * 1,000 / l. So you’ll multiply your kVA rating by 1,000 and then divide by the amperage. If your transformer has a kVA rating of 75 and your amperage is 312.5, you’ll plug those numbers into the equation — 75 * 1,000 / 312.5 = 240 volts.
