How many watts does a 5 hp motor use?

It is easy to convert HP to watts based on the equivalence of 746 watts per horsepower and arrive at 5 HP = 3730 watts. However, in practice, motors seldom run at their nameplate current (FLA or Full Load Amperage).

What size breaker do I need for a 5 hp motor?

How to Calculate How What Size Circuit Breaker a Machine will Need:

HorsePower of Main Motor 220 Volts, 1 phase 220 Volts, 3 phase
3 16.8 8.4
4 22.4 11.2
5 28 14
6 33.6 16.8

How much power does a 2 hp motor use?

So, 1 HP for 24 hour = 746×24= 17904 Watt-hour which is equal to 17904/1000= 17.904 units. How many kWh does a 10 hp motor use?

How many watts does a 1 hp electric motor use?

How much power does a 1hp motor consume?

So, 1 HP for 24 hour = 746×24= 17904 Watt-hour which is equal to 17904/1000= 17.904 units. Hence, 17.904 units of Power will be consumed by the 1 HP motor when run continuously for 24 hours.

How much electricity does a 30 hp motor use?

Designed power capacity of a motor 30 HP,at 415 V, 3 phase power factor 0.8 (assumed). Full load current is , one HP is 745 w, 30 HP is 30 x 745 =23.35 kW, W = V x I x pf, 23.35 = 415 x I x 0.8, I = 23.35 divided by 415 x 0.8 = 67 amps.

How many watts does a 2.5 hp motor use?

One horsepower is equal to 745.7 watts. When you multiply 745.7 watts by 2.5 hp, you get 1,864.25 watts. Energy costs are calculated in kilowatt-hours, and to get kilowatt-hours, you multiply watts by hours and divide by 1,000.

How do I convert HP to amps?

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.

What size breaker do I need for a 7.5 hp motor?

Per table 310.16 – #6 wire is required. A minimum (nominal) breaker is also 50 amps but can be increased to a maximum size of 100 amps. For the purposes of the compressor a 60 amp breaker should be used.

How many amps does a 5 HP 3 phase motor draw?

These are only intended to be guidelines and in all cases the full load amps of the motor nameplate should be used for final calculations.

Here are the Full Load Amp (FLA) values for typical 230VAC and 480VAC 3 phase motors.
