## What size breaker do I need for a 10 hp motor?

Full Load Current: Three Phase AC Motors

Motor Horsepower Size Breaker
5 230V 460V 15 15
7-1/2 230V 460V 40 30
10 230V 460V 50 30
15 230V 460V 70 40

## Can 10 hp motor run on single phase?

No you can’t because, single phase winding cannot produce a rotating magnetic field whereas the three phase winding displaced by 120 degree electrical will produce a rotating magnetic field which is the reason why we call a three phase induction motor a “Self starting device”.

## How do I convert HP to amps?

How to Convert Horsepower to Amps

1. Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.
2. Watts = Horsepower × 746.
3. Watts = Wattsη
4. Amps = Watts ÷ Volts.
5. Amps = HP × 746V × η × PF.

## How do you calculate 10 hp motor current?

A 10 HP AC single phase motor has 230 Volts of voltage flow with 0.86 power factor, calculate the current. AC Current = 746*10 / (230*0.86) = 37.71 Amps.

## What size breaker do I need for a 10 amp motor?

If you are connecting your 10 amp load to a standard electrical circuit in North America, a 15 or 20 amp circuit would be appropriate. If it’s a motorized load, I recommend a 20 amp circuit because inrush current at startup can “nuisance” trip a 15 amp breaker.

## How many amps can you put on a 20 amp breaker?

The standard for most household circuits are rated either 15 amps or 20 amps. An important note to remember is that circuit breakers can only handle about 80% of their overall amperage. That means a 15-amp circuit breaker can handle around 12-amps and a 20-amp circuit breaker can handle about 16 amps.

## How fast is 10HP?

As a practical matter , you can get from fifty to maybe eighty mph with a ten hp engine on a light weight motorcycle if you tuck in and have a good fairing . This means a racing style bike at the hight end. May be twenty five to thirty five mph in a light weight automobile with low aero drag on a level road.

## What is the biggest single-phase motor?

The largest single-phase motors suitable for residential use top out at 10 horsepower. A few commercial applications may be found for higher voltage single-phase motors at up to 15 horsepower, but these are rare and require 480 volts of single-phase current to operate.

## How many HP is 15 amps?
