# Quick Answer: What Is The Full Load Current Of A 1 Hp Motor?

## How many amps is a 3 phase?

If a three-phase supply is available, then the 24,000 watts are divided by 3, meaning that 8000 watts is being used per phase.

Now the current per phase is also down to a third of what it would be with a single phase supply (about 30 amps per phase, rather than 100)..

## What is a full load current?

A full load current is the largest current that a motor or other device is designed to carry under particular conditions. … A full load current is the largest current that a motor or other device is designed to carry under particular conditions.

## How many amps does a 1.5 hp air conditioner use?

As 1.5 horsepower air conditioner that falls into, around 12,000 BTU, in USA recommend 117 volt on 20 ampere breaker. Depend if air conditioner that has 220 volt or 110 volt. In UK, standard 13 amp wall plug that properly run air conditioner.

## What is the full load current of a motor?

The full-load amperes (FLA) is the current the motor draws while producing its rated horsepower load at its rated voltage. NEC Tables. The full-load current (FLC) is the current value listed in Tables 450.247 through 450.250.

## What is the starting current of 1 hp motor?

For single phase motors, NEC table 430-148 gives 230 Vac full load current of 8 amps for a 1 HP motor. Note, that a 1 HP motor not fully loaded (good practice) will show current draw of less than 8 amps.

## How do you calculate motor full load amps?

The motor FLA calculator uses the following formulas:Single Phase AC Motor FLA (Amperes) = (P [kW] × 1000) / (V × cos ϕ)Single Phase AC Motor FLA (Amperes) = (P [HP] × 746) / (V × cos ϕ × η)Three Phase AC Motor FLA (Amperes) = (P [kW] × 1000) / (V × 1.732 × cos ϕ)More items…

## What is the formula of load?

Calculating an Electrical Load in a Simple Circuit Let Power = Voltage * Current (P=VI). Let Current = Voltage/Resistance (I=V/R). Apply Kirchoff’s Second Law, that the sum of the voltages around a circuit is zero. Conclude that the load voltage around the simple circuit must be 9 volts.
