The way the question is stated this type of a transformer is a step up transformer. A voltage of 120 volts is applied to the primary side of the transformer and the 230 load is connected to the secondary side of the transformer. Since you also used the category Pool Heating, the transformer must be used in the control unit of the pool heating controls.
The other option is that the transformer is a step down transformer 230 to 120 volts and is used for 120 volt control voltage, the primary is then connected to the 230 volts. In the control unit, the transformer will probably be connected to the supply 230 volts circuit from the heater circuit. There should be an in line fuse between the incoming 230 volts and the primary connection to the control transformer. The fuse should be rated at 1/2 amp for proper protection.
To get 480V from 120V, you can use a transformer. A transformer with a turns ratio of 4:1 will step up the voltage from 120V to 480V. Make sure to follow proper safety protocols and consult an electrician if needed.
To convert 7.5 VA to amperes, you can use the formula: Amperes = VA / Volts. For example, if the voltage is 120V (typical for household circuits), then 7.5 VA / 120V = 0.0625 amperes.
No, a light fixture designed for 480V cannot be simply rewired to operate on 120V. It would require a new ballast and potentially other components to be compatible with the lower voltage. It is recommended to consult a certified electrician for such modifications.
No, you cannot directly convert a 30 amp 120V RV receptacle into a normal 120V outlet. They have different wiring configurations and power capacities. It is recommended to install a new standard 120V outlet for regular household use.
To convert amps to watts, you also need the voltage. The formula to calculate power in watts is Watts = Amps x Volts. If the voltage is 120V, then 37.5A would be equivalent to 4500W (37.5A x 120V = 4500W).
Not directly, you would need to transform 480v circuit to 120v with a transformer first.

Theoretically that can be done with transformers, but the power available would still be limited by the circuit breaker on the original 120 v supply.
In the supply industry it refers to circuits of below 1000 volts. Common voltages used are 120v, 208v, 230v, 240v, 277v, 400v, 415v, 480v.
The kVA rating will be listed on the transformer's nameplate, which is usually on the front of the transformer. The 480v to 120v is irrelevant, because many transformers with different kVA ratings convert 480 volts to 120 volts. The kVA ratings can be different and thus affect the rated current through the transformer.
To convert 7.5 VA to amperes, you can use the formula: Amperes = VA / Volts. For example, if the voltage is 120V (typical for household circuits), then 7.5 VA / 120V = 0.0625 amperes.

A: My advice is do not try it 120 v will require 480v /120 or 4 times the current. assuming 100% efficiency. a transformer can do it but there will be a loss of 20% . House wiring is 15 amps per circuit . So if your whatever unit needs more the 3 amps it just cannot be done. A PWM can also do this job more efficiently but then again the total power is in question.
To convert amps to watts, you also need the voltage. The formula to calculate power in watts is Watts = Amps x Volts. If the voltage is 120V, then 37.5A would be equivalent to 4500W (37.5A x 120V = 4500W).
#12 wire will carry about 20 amp 20 X 480 volts = 9600 watts 20 X 120 volts = 2400 watts 4 times.
It will work it you use 240 volt light bulbs.
