Want this question answered?
Assuming a household voltage of 120 volts and a power factor of about .8 for the fan motor we have watts = volts x amps x PF. Amps = 90 / (.8 x 120) = 3 / 3.2 = .94 amps
A #8 copper wire with an insulation rating of 90 degrees C is rated at 45 amps.
A #8 copper wire with an insulation rated at 75 or 90 degrees C is rated at 45 amps.
A 2/0 copper conductor with an insulation rating of75 and 90 degrees Care rated at 175 and 185 amps respectively.
A 4 mm diameter copper wire with an insulation factor of 75 or 90 degrees C is rated at 65 amps.

how to set a trim tab on a 90 hp yamaha outboard
Aluminum 4/0 wire car carry 180 amps at at 75 degrees Fahrenheit or 205 amps at 90 degrees. .
The weight of the 90 hp Yamaha, as well as other brands, varies with year model. On average the Yamaha 90 weighs in at 256 lbs.
The formula you are looking for is; Amps = HP x 746/1.73 x Volts x %eff x pf. 350 x746/1.73 x 480 x .90 x .90 = 261100/672 = 389 amps. This amperage assumes that the efficiency of the motor is at 90% and the power factor of the motor is also at 90%.
what is the plug gap on a 90 hp yamaha 2 stroke engine?
The listed dry weight of a 1986 model, 90 hp Yamaha outboard is 270 lbs.
90 kW on 480 volts single phase would be 187.5 amps. On 480 v 3-phase it would be 108 amps.
A #8 copper wire with an insulation rating of 90 degrees C is rated at 45 amps.
