## How do I convert HP to amps?

Converting horsepower to amps can be done in a few simple steps, or using this simple formula.Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.Watts = Horsepower × 746.Watts = WattsηAmps = Watts ÷ Volts.Amps = HP × 746V × η × PF..

## How many amps is a 1/6 hp motor?

AC Motor Full Load AmperesHP110-120 Volts1/64.42.21/45.82.91/37.23.61/29.84.910 more rows

## What gauge wire do I need for 200 feet?

To feed a 100 ampere secondary panel 200 ft. from the main panel, you’ll want to use 1 AWG copper or 2/0 aluminum conductors. This is large enough to safely carry 100 amperes, and to maintain power quality over the distance.

## What is the formula for calculating cable size?

Current rating for 35°C (95°F) = 31 x 0.97 = 30 Amp. Since the calculated value (30 Amp) at 35°C (95°F) is less than that of current carrying capacity of (7/1.04) cable which is 31A, therefore this size of cable (7/1.04) is also suitable with respect to temperature.

## What are the standard cable sizes?

Standard Cable & Wire SizesInternational standard wire sizes (IEC 60228)0.5 mm²0.75 mm²1 mm²6 mm²10 mm²16 mm²70 mm²95 mm²120 mm²300 mm²400 mm²500 mm²Apr 9, 2012

## What is cable size?

A few key terms: Cross sectional area of the conductor – sometimes called ‘cable size’ Given as mm², it describes the total cross-sectional area of the copper conductor. Cable will be sized 1 mm², 2 mm², 4 mm² etc. and may be written as 1 mm, 2mm, 4mm.

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

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

## What size cable do I need for 32 amps?

## How do you calculate the cable size of an HP motor?

Calculate Size of Cable for Motor (As NEC)Size of Cable for Branch circuit which has Single Motor connection is 125% of Motor Full Load Current Capacity.Example: what is the minimum rating in amperes for Cables supplying 1 No of 5 hp, 415-volt, 3-phase motor at 0.8 Power Factor. Full-load currents for 5 hp = 7Amp.Min Capacity of Cable= (7X125%) =8.75 Amp.Aug 1, 2019

## What size wire is used for well pump?

If you are doing residential work, most of the pump cable you use will be in the #6 to #14 AWG range.

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

## How do I choose a motor wire size?

Cable derating Amp (269.28 Amp) is higher than full load current of load (41 Amp) = OK.Cable voltage Drop (0.032%)is less than defined voltage drop (5%) = OK.Cable short circuit capacity (28.20 KA) is higher than system short circuit capacity at that point (26.2 KA) = OK.

## How do you determine cable size?

Let’s select 3.5 core 70 Sq.mm cable for single run.Current capacity of 70 Sq.mm cable is: 170 Amp, Resistance = 0.57 Ω/Km and. … Total derating current of 70 Sq.mm cable = 170 · 0.93 = 159 Amp.Voltage Drop of Cable = (1.732 · Current · (RcosǾ + jsinǾ) · Cable length · 100) / (Line voltage · No of run · 1000) =Jun 30, 2014

## What size breaker do I need for a 1/2 HP well pump?

15 amp 2Reach4 Well-Known Member The manual for your pump probably recommends a breaker size. For a 1/2 HP submersible pump, a 15 amp 2 pole breaker would be normal. You can run 12 AWG, but unless the run is very long, 14 AWG is sufficient. Bigger wire would let you switch to a bigger pump later if you wanted.

## What is the difference between a 2 wire and 3 wire submersible pump?

The difference between a 2-wire and 3-wire pump is based on the type of motor that is used. … It is called a “3-wire” due to the three “hot” leads, though there are actually four wires when you count the ground wire. The 2-wire motor requires no control box because is does not use a starting capacitor.
