Best Answer

1. With a transformer

2. With a specialized power drop from the power company.

3. Across two hot phases in a 240v two or three phase power drop in Europe, etc (not sure about this one, I have heard that it might not work this way).

To get 480V AC, you typically need to use a three-phase transformer or connect three single-phase Transformers in a wye or delta configuration. Each phase will provide 277V, and when measured between any two phases, the total voltage will be 480V. Make sure to consult with a qualified electrician to ensure proper installation and safety.

You have two devices that are rated at 230 VAC single ph and your supply voltage is 480 VAC 3 ph you need a 480 VAC 3 phase to 230 VAC three phase xfrmer how do you calculate the xfrmer size?

The transformer size is calculated by using the load current that is required on the secondary side of the transformer. This secondary current is multiplied by the secondary voltage times 1.73. This total is then divided by 1000 to give you KVA. KVA = I x E x 1.73/1000.


How many amp in 480 vac 3- phase primary transformer if the secondary it's 120 vac?

This 480-v three-phase transformer probably has a 208-v three-phase secondary which has 120 v from each line to neutral. In that case the primary current is 0.433 times as much as the secondary current, so 100 amps in the secondary means 43.3 amps in the primary.

What is the voltage of line voltage?

It varies from country to country. In the USA it is 110 volts, in the UK it 230 volts +/- 10%/6%. In practise in the UK it is 240s volt +/- 6%, the slightly odd looking specification allows harmonisation with rest of Europe. In all these cases, the mains voltage is supplied AC (alternating current) and the voltage is given as root mean square (RMS). The peak voltage in the UK is 384 volts.

How do you change your wet dry shop vac from dry to wet?

Removing the filter from your wet / Dry vac makes it a wet vac. Only vacuum water with a wet/dry rated vac. If you use a regular vac you might ruin the vac or electrocute yourself.
