Convert kwh to amp. | Information by Electrical Professionals for ...
Apr 27, 2010 · So amps are equal to 1000 times kilowatts divided by volts. amps = 1000 ? kilowatts / volts Or A = 1000 ? kW / V Kilowatts to amps example What is the current in amps when the power consumption is 0.33 kilowatts and the voltage supply is 110 volts? I = 1000 ? 0.33kW / 110V = 3A If you want to figure how much kW per Hour:
calculating amps from a give kW load | Information by Electrical ...
Oct 24, 2007 · I am trying to calculate the FLA for a motor given the motor kW rating (this is a German motor and they like to give their ratings in kW rather than hp.)but my numbers are not matching up with those given by the manufacturer. I am trying to calculate the FLA as an exercise for myself to try to figure out how to derive them from a given kW.
Kw to kva | Information by Electrical Professionals for Electrical ...
Dec 12, 2024 · The relationship between kW (real power) and kVA (apparent power) is: kVA=kW/Power Factor In practical terms, when calculating load, particularly for non-linear or inductive loads, the NEC requires you to use the apparent power (kVA) rather than just the real power (kW) because the power factor affects the current drawn by the equipment.
5 Ton AC load | Information by Electrical Professionals for Electrical ...
Dec 17, 2008 · The KW value above needs to be divided by a factor between 2 and 4. Power use is roughly TONS * 12000 / EER. Note that this method is not a good way to derive amps or MCA -- need the nameplate or datasheet for that.
Converting KW/hr to amps | Information by Electrical Professionals …
May 31, 2018 · 132 KW/hr divided by 24 hours = 5.5 KW/hr divided by 240V = 22.92 amps ave per hour and therefore if I assume most of the usage is during an eight hour period, I could guess that: 132 KW/hr divided by 8 hours = 16.5 KW/hr divided by 240V = 68.75 amps ave per hour
kw vs kva | Information by Electrical Professionals for Electrical ...
Jan 27, 2018 · When you have motors or other less simple loads, then the waveforms of volts and amps may not line up. That's when you get a power factor below 1. KVA is then more than kW. In extreme cases it could be a problem where amps is actually more than kW/V. If you use kW/V to size conductors and equipment you could be undersizing for actual amps.
Size of circuit breaker required | Information by Electrical ...
Aug 30, 2007 · If no MCA value, the convert KW to amps at the supplied voltage and phase. If this is 240V single phase, then the amps would be 15000/240 = 62.5A. You are required to treat this as a continuous load, so ampacity requirement is 62.5*1.25 = …

Aug 1, 2006 · Please help me make sure this calculation is correct for a 12.9 KW range. 12.9 KW-12.0KW= .9 KW .9KW x 5%=.o45% or 100.045% 100.045% x 8kw= 8.0036kw 8.0036kw rounds down to 8KW or 8000 W/240V = 33.3 amps wire size # 8 thhn awg. breaker 40amp Thank you
11.6 KW range | Information by Electrical Professionals for …
Nov 21, 2009 · Ok this is a spin of an earlier thread. I just installed another range and the rating is 11.6 KW the instructions say "Amp rating @ 240v = 40 KW rating @ 240v = 11.6 11.6 KW = 48.3 amps correct? So where how is it rated at 40 amps? Link...
interpreting Utility meter data and calculating amps
Jul 1, 2015 · If the load factor were very high, you might assume the peak kW is closer to the average kW. Not the case here. However, for amp calculation example purposes, let's assume 90% pf. With a peak kW of 146.56 we get the peak kVA as 146.56 / 0.9 = 162.84 kVA. At 208Y/120 this yields 162.84 / sqrt(3) / 0.208 = 452 amps.
