In WYE 480 VAC each leg to neutral is equal to 277 volts. 480 / 1.73 (sq root of 3) = 277.
Maybe if the voltage across capacitor will never exceed 450 VAC.
There are many different kinds of accessories central vac has. Examples of the different kinds of accessories that central vac has includes bags and fillers.
You can use a transformer with a turns ratio of 24:5 to convert 24 VAC to 5 VAC. This means the primary winding has 24 turns for every 5 turns on the secondary winding, which will step down the voltage proportionally. Make sure the transformer is rated for the appropriate power and frequency.
0.25 of 480 is 120. 480 multiplied by 0.25 (1/4) is 120 or 480 divided by 4.
The ratio for a 480 VAC to 120 VAC is 4 to 1.

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.
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.
To calculate the kVA rating of the transformer, you can use the formula: kVA = (Voltage × Current) / 1000. In this case, the secondary winding delivers 10 amps at 480 volts. Therefore, the kVA rating is (480 V × 10 A) / 1000 = 4.8 kVA.
10 AWG should never carry more than 30 Amps.
In WYE 480 VAC each leg to neutral is equal to 277 volts. 480 / 1.73 (sq root of 3) = 277.
All electrical equipment, regardless of the voltage, should have a voltage supply that is no more than plus or minus 5 per cent of the equipments stated voltage requirement.

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.
