A #6 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 65 amps.
A #8 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 45 amp which is too small for a 45.5 amp load.
10 mm2 cross section should be sufficient (#6 wire?)
At the service entrance you will need AWG 1/0 gauge.
4800
AWG # 10.
Depends on the amperage of the Jacuzzi and if it is 120 or 240 volts.
10 gauge will work fine.
A #14 wire will do the job.
10 mm2 cross section should be sufficient (#6 wire?)
For a 240 volt 40 amp circuit, the appropriate wire size is typically 8 AWG (American Wire Gauge) for copper conductors.
At the service entrance you will need AWG 1/0 gauge.
The ampacity of an 8 gauge wire at 240 volts would depend on the specific type of wire and the installation conditions. Generally, an 8 gauge wire can safely carry around 40-50 amps of current. It is important to consult the National Electrical Code (NEC) and local regulations for precise guidance.
30 amps.
10 gauge
Wire sizes are governed by the amperage the wire is to carry. To answer this question the load current is required.
