This is an estimator for busbar current carrying capacity. For the exact results please refer to your busbar provider’s data.
Formula is motorRatedTorque = (hp/rpm)*5252 lb-ft

if you enter KW, volt and power factor, the tool will return min contractor size.
Fuse selection is important in an electrical circuit, because a very rapid acting fuse might open in 0.1 seconds, a fast acting fuse might open in one second, and a slow acting fuse might take tens of seconds to open if a current of 20A was flowing through a fuse rated at 10A.Continue reading EE02:FUSES BY MARKING
Capacitor manufacturers generally give the value of capacitor on capacitor but, in some cases there may be not enough space. In that case, they use simple notation. If it is 2 digits number then no issues. You can say the value seen is the value on capacitor. But if it has 3 digits then the first two digit you take as is and remaining last digit is the number of zeros following that first two digits. See table below;Continue reading EE99 – CAPACITOR VALUE READING TABLE
