208V to 230V buck boost

[cppoly]

If an appliance is 230V and there's only 120/208V available from a panel, would a buck boost transformer would be needed?

For a 2,300 watt, 230V load, this would be a 3 kVA transformer, which is 3,000 / 208 = 14.4 amps * 1.25 = *1.25 = 18 amps = 20 amp OCPD primary?

Then, would a 20 amp disconnect fused at 15 amps be needed on the secondary?

You may have already done this, but I’d make sure the load can’t be used on 208 before going the transformer route.

I would, and, simply put the boost transformer between the OCPD and the appliance it is serving.

Does the load have a neutral?

Buck boosts are sized by the voltage Change and the current, IIRC.
22 * 10 = 220 . There is no secondary.

The answer depends on what the appliance actually is. Many/most times it can just run direct on 208 but must be considered each time.
