To answer this question, wire size is rated in the amount of amperage that it can legally carry. The formula to find amperage when the HP is known is I = HP x 746/1.73 x E x %eff x pf.
A standard motor's efficiency between 5 to 100 HP is .84 to .91.
A standard motor's power factor between 10 to 100 HP is .86 to .92.
Amps = 30 x 746 = 22380 = 22380/ 1.73 x 480 x .87 x .87 = 22380/629 = 35.6 amps.
The electrical code states that a motor conductor has to be rated at 125% of the motors full load amperage. 35.6 x 125% = 44.5
A #8 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 50 and 55 amps respectively.
For a 480V 60A load on a 10-foot cord, a 6 AWG stranded SOOW cord would be recommended to ensure proper electrical conductivity and safety. It's important to consult with a qualified electrician to confirm the appropriate cord size based on installation specifics and any local electrical codes/regulations.
The size of a power adapter is typically measured by its dimensions in millimeters or inches. This includes the length, width, and height of the adapter. Additionally, the power rating in volts and amps is also an important factor when considering the size of a power adapter.
Yes the rated voltage is a maximum. A 250 v cord might be slightly thicker than one for 125 v. <<>> The voltage rating of an electrical extension cord is the insulation factor of the cord. These cords come in two insulation ratings, 300 volts and 600 volts. If the voltage rating is within the parameters of the cord maximums then it is safe to use it on that voltage. The amperage of the cord is based on the wire size of the cord's conductor. The rating of 10 amps will fall within the #14 cord size. Remember the longer the cord the larger the wire size should be to prevent voltage drop at the connected load end.
Lamp cord is #18 in size and is rated for 10 amps. This type of wire is strictly for use on lamps only and not to be used for power wiring.
It is not safe to run a 1 hp motor with a 14 gauge cord. A motor of that size typically requires at least a 12 gauge cord to handle the current draw. Using a lower gauge wire can result in overheating and potential fire hazards. It is best to match the wire gauge with the motor requirements to ensure safe operation.
With that size of load and a voltage of up to 300 or 600 volts, any extension cord can be used.
With that size of load and a voltage of up to 300 or 600 volts, any extension cord can be used.
The starter motor of a diesel generator is a DC motor. Depending on the size of the diesel engine the starter motor could be 12 volts or 24 volts. Sometimes more that one battery is used at the specific voltage. These batteries are connected in parallel to create more amp hour cranking power.
12/2 with ground.
I would go with 20 amp 3 pole 15 amp will also do

No they don't
Power is the product of amps x volts, it has nothing to do with wire size.
It depends on what you need the power cord for. Usually you will have a manual that can tell you exactly what is needed. If not, just look carefully at the connecting points and see what the shape/size of the power cord needed is. Depending on the appliance, you need to pick out the right cord it tells you it needs.
depends what the source voltage isone horsepower equals to 746watts (assuming 100% efficiency)746 watts divided by voltage source equals current (amps)AnswerIn countries, such as the USA, where the horsepower is still used as a means of measuring power, it is always used to measure the output power of a motor.So, in order to determine the current drawn by the motor, you will first need to find out its input power. The input power is the output power divided by the machine's efficiency. Once you know its input power, then you can find its current by dividing the input power by the supply voltage. In practise, you will need to use a wattmeter to determine its input power.
A 1HP 3-phase motor typically operates at 208-230 volts and has a current rating of around 3-4 amps. It runs at a speed of 3450 RPM and has a frame size of 56. The motor is designed for industrial applications requiring higher power output and efficiency.
YES ALL CONECTIONS MUST BE SQUEAKY CLEAN AND THE PROPER SIZE POWER CORD MUST BE USED..
