what size wire would be required for an ak012 with a power supply of 208/240-3-60 hz
#6 AWG
7.2kW shower = 32 Amp fuse = 6 mm2 cable size7.5kW shower = 40 Amp fuse = 10 mm2 cable size8.5kW shower = 40 Amp fuse = 10 mm2 cable size9.5kW shower = 40/45 Amp fuse = 10 mm2 cable size10.5kW shower = 45 Amp fuse = 16mm2 cable size
A #8 aluminium wire with an insulation factor of 90 degrees C is rated at 45 amps.
Both a 45 amp and 50 amp breaker would require 6 AWG wire. So if you have 6 AWG wire and any devices like an outlet are rated at 50 amps or greater you are okay.
This is not a good idea to do. Sometimes just that little bit of extra current that the 45 amp fuse will allow to reach the 40 amp load might be enough to destroy the device.
A 40 amp breaker is used in conjunction with AWG # 8 copper wire. The black and red wires are connected to the breaker. The ground wire is connected to the ground bar and the white wire is connected to the neutral bar.

45
assuming this is a 12 volt system....45 amps.

The question does not give enough details to answer
6 AWG. It is the amps that matter most, but there are other elements in that a maximum voltage may be specified as it relates to the insulation on the wire. In an auto the wire is usually stranded rather than solid.
Number 8. Wire <<>> A #8 copper conductor with an insulation factor of 75 and 90 degrees C are both rated at 45 amps.

Answer for USA, Canada and countries running a 60 Hertz supply service.With out knowing the specifics of the stove, a home is usually prewired with a #8 wire which has a rating of 45 amps. This wire is protected with a two pole 40 amp breaker.
No a #12 wire is only rated for 20 amps. The 40 amp breaker will not protect the #12 wire. A 40 amp breaker should have a #8 wire connected to it which is rated at 45 amps. The only time that a breaker is allowed to be bigger that the wire size rating according to the electrical code is when a motor is connected to the breaker. This is to stop the 300 percent inrush of the motor full load amps from nuisance tripping a smaller sized breaker.
