You can click through to FastQuote, our online quotation tool, to select a cable that meets your size and specification requirements. In both BS and IEC calculations, the KW calculation is based on a power factor of 0.8. The cable size results for International standard cable are calculated from IEC 6: Low Voltage Electrical Installations, selection and erection of electrical equipment – Wiring systems and are based on 230V and 415V voltage drop. If, for example you consume 100 kwh in a day at 240VAC and assume a steady state load, thats 100 kwh divided by 24 hours, or a 4.17 kw load. It covers Low Voltage armoured AWA and SWA cables, insulated cables including twin & earth and 6491X, and insulated and sheathed cables in both PVC and LSZH such as H07ZZ-F and SY cable. Good answers, but more simply,you can convert kilowatt hours to amperes if you know the voltage at which your loads operate and assume a steady state load (a big assumption). What is the current in amps when the power consumption is 0.33 kilowatts and the voltage supply is. Here’s the short summary for 1 kVa for 120-volt, 22o-volt, and 12-volt (battery) circuits: 1 kVa to amps (120V) 8.33 A. So amps are equal to 1000 times kilowatts divided by volts. The results for British standard cable are calculated from BS7671 (18th Edition) Requirements for Electrical Installation, IEE Wiring Regulations, and are based on 230V and 415V voltage drop. Using this formula, we have prepared a calculator to convert kVA into amps. Complete the sections below to calculate your results. Open drip-proof (ODP) or fully enclosed fan-cooled (TEFC) 1 hp and larger motors that operate more than 500 hours per year.Eland Cables' Cable Calculator can help you determine the most appropriate cable size for your installation against British and IEC standards. Which will result in: 21.47Hp.Ī motor of a compressor has a power of 84kW, how much power in Hp will the motor have?Īnswer: // To move from mechanical kW to Hp you simply have to divide the kW by the constant 0.745699, which will result in: 2.609kW.Įlectric motors built according to NEMA Design B must meet the following efficiencies: Hpġ) Design NEMA B, individual speed 1200, 1800, 3600 RPM. 36 kW tankless electric water heater (240 V). Below you will find 3 examples of a kW to Amps conversion for: 4 kW central air conditioner (220 V). As follows: you have an electric generator of 38.5kW, with an efficiency of 84%, to know the equivalence in Hp, you must multiply 38.5kWx0.84 (84%) and divide the result by 0.746, resulting in: 43.35Hp.Īn industrial engine has a power of 21.6kW and 82% efficiency how many hp has the engine ?.Īnswer: // First you must multiply the kW by 82% (0.82) and finally divide this result by 0.746, as follows: (21.6 × 0.82) / 0.746 = 23.74kW.Īn electric motor of a fan is 18.8kW, with an efficiency of 89.3% (0.89), how many Hp has the motor?Īnswer: // You must multiply 18 × 0.89 (It is 0.89 in decimals), and then divide the result by 0.746. Power (kW) I (A) V (V) You can use this kilowatt to amperes converter. There are three types of Hp, the most used is the electric Hp therefore to convert from electric kW to Hp you must use the formula: kW圎 / 0,746 and then replace the variables in the formula. How to convert from kW to Hp in 1 only step: KW to Hp, table for conversion, equivalence, transformation:įormulas to convert, calculate, transform from kW to Hp: In this formula, the amount of power (in kW) is equal to the power factor of the load (PF) multiplied by the phase current measured in Amps (A), times the RMS voltage (V), and divided by 1000.
