WebSep 1, 2008 · The other motor(s) in the group (phase) is the 10-hp 3-phase motor, as indicated by the shaded area. The NEC does not permit the use of motor nameplate FLA to determine the conductor ampacity; the branch … WebMar 21, 2024 · The difference is in the fact that for FLA, you are looking at the rating of the MOTOR, RLA you are looking at what the LOAD uses. So to determine RLA, the HP that you use would be the actual SHAFT HP under the rated operating load. If you don't know that, then you can't calculate RLA. Thank you, got it completely know.
Electric Motor Horsepower & Wiring Guide
WebHorsepower = 200, Voltage = 230 Chart value of 480A multiplied by 1.25 = 600A. Closest standard current transformer ratio is 600/5. Example over 200 horsepower: Horsepower = 275, Voltage = 460 Chart value of 1.2A/HP multiplied by 275 HP = 330A. 330A X 1.25 = 412.5A. Closest standard current transformer ratio is 400/5. Web= hp x 0.7457 η fl Where: Load = Output power as a % of rated power P i= Measured three-phase power in kW P ir= Input power at full-rated load in kW Load = P i P ir x 100% 4 Line Current Measurements The current load estimation method is recommended when only amperage measurements are available. chic and trendy accessories
