# How many amps does a 5 hp motor use?

Example: A 5 HP motor at 230V, 3PH is12. 4 amps.

Example: A 5 HP motor at 230V, 3PH is12. 4 amps.

Similarly, how many amps are in a HP? Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm’s Law, which is amps times volts equals watts. Multiply the horsepower by 746 watts. For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.

Additionally, what size breaker do I need for a 5 hp motor?

In fact code recommends a 60 amp circuit breaker for a 5 hp 230v motor, but with overload protection.

How many watts does a 5 hp motor use?

### How do you convert HP to amps?

Multiply amps by volts to obtain the motor’s wattage, or watts (A * V = W). Wattage is the same type of unit as horsepower, a measure of power, so it can readily be converted (like gallons to quarts). The wattage for the blender example would be 5 A * 115 V = 575 W.

### How many amps does a 1 HP 3 phase motor draw?

### What is meant by 1 ampere?

An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second. The ampere is named after Andre Marie Ampere, French physicist (1775-1836).

### How do I calculate horsepower?

To calculate the horsepower of a car, start by finding the engine’s torque value and engine speed in the owner’s manual. Multiply the torque by the engine speed, and then divide that number by 5252. The answer is the horsepower for the car’s engine.

### What size wire do I need for a 20 hp motor?

### How do you size a 3 phase breaker?

For 3-phase loads, you divide the VA by the nominal voltage and by the square root of three (approximately 1.732). If your total 3-phase load in a 480V system is 50,000VA, what size breaker do you need? 50,000VA ÷ (480V × 1.732) = 60.2A. The next size up is 70A.

### What size breaker do I need for a 15 amp motor?

Use a 12 wire and a 20A breaker. 15A ends are allowed on 20A circuits.

### How do you size a motor fuse?

You must size the conductors at 125% of the motor FLC [430.22(A)]. You must size the overloads no more than 115% to 125% of the motor nameplate current rating, depending on the conditions [430.32(A)(1)]. You must size the short-circuit ground-fault protection device from 150% to 300% of the motor FLC [Table 430.52].

### How do I calculate wire size?

Divide the voltage running through the cable by your target current. If, for instance, 120 volts will act on the cable, and you want 30 amps to run through it: 120 / 30 = 4. This is your target resistance, measured in ohms. Multiply the cable’s length by its material’s resistivity.
