To wire a buck-boost transformer from 208V to 240V, connect the 208V input leads to the appropriate taps on the transformer to step up the voltage. The output leads on the transformer will then provide 240V. Be sure to consult the transformer's wiring diagram and follow all safety guidelines during installation.
Single phase or three phase? 120/208 would be measured hot to ground for 120 and hot to hot (phase to phase) for the 208 reading. Any hot to ground will read 120 and any two phases together will read 208.
208 v is a three-phase supply voltage used in North America, carried on a 4-wire system. The voltage between one of the three live wires and the neutral wire is 120 v and a single-phase supply can be taken by using one live and the neutral. If in doubt about the connection consult an electrician.
Yes a transformer should be used. The steam table needs its correct voltage otherwise on 240 volts it will operate over its given specified nameplate wattage. A 208 volt heating element run off of 240 volt will have an output increase by 75 percent.
For a 225 amp 208 volt 3 phase circuit, you would typically need to use a 3/0 AWG copper wire or a 250 kcmil aluminum wire. Be sure to consult with local electrical codes and regulations to ensure compliance with specific requirements for your installation.
Changing the voltage is done by using a transformer. These voltages are dangerous and the job should be done by an electrician who knows the safety regulations that must be followed in your country.
The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.
Single phase or three phase? 120/208 would be measured hot to ground for 120 and hot to hot (phase to phase) for the 208 reading. Any hot to ground will read 120 and any two phases together will read 208.
you need a step up transformer
You don't. Every circuit needs a return wire back to the source.
Yes, with an auto transformer. It is a transformer with multiple taps on the winding. Connect the 208 volts across the common tap and 208 volt tap. Then connect the load across the common tap and the 240 volt tap.208 VAC usually comes from one floating side of a Delta 3 phase transformer.240 VAC usually comes from a grounded center tapped transformer.Using an autotransformer would be very hazardous and violate code. Probably tripping the 208 VAC breakers.The only way to do it correctly would be with a transformer with a 208 VAC floating primary and a 240 VAC grounded center tapped secondary.

First of all there is no common three phase 120 volt service. There is in North America a three wire 120/240 volt single phase service. That being said, if you want to change a 120 volt source to 240 volts it must be done with a transformer. Its classification is a step up transformer. The primary side of the transformer H1 - H2 will be connected to the 120 volts. The secondary side of the transformer X1 - X2 will be connected to the 240 volt load. The transformer is sized by the current required by the 240 volt load.
As with any electrical installation, the wire size used depends on the expected maximum current the wire will carry. That cannot be determined by voltage alone.

A three phase four wire system allows for two voltages from a single three phase transformer. The transformer configuration is a wye or star connection. It is used in commercial and industrial applications. Apartment buildings are now starting to use a three phase four wire service distribution system. Some wye connection voltages are 120/208 volts, 480/277, and 600/347. The lower voltage is derived from the sq root of 3 divided into the three phase voltage.
