Do they provide the FLA? Air compressor vendors lie about horse power!!! Going by code we would use the fla book value 5hp or 28 amps plus 125% because it is a motor load or 35 amps requiring a 35 but probably a 40 amp breaker and #8 wire.
In reality your fla is probably going to be closer to 13 amps ( 2.98kw /240v) and that will be fine on a 12 awg circuit with a 20 amp circuit breaker.
Why do I say air compressor (and vacuum cleaner) companies lie? With locked rotor no work is being done and the definition of 1 horse power is the work of 746w. They put the LR value and at locked rotor no work is done.
