    Centripetal forces effect on weight

    Actually, I don't think that any amount of increase in rotational speed will provide sufficient centripetal acceleration to overcome Newton's Gravitational force F=G(m1xm2)/r^2. Unless you do something like make the planet's mass that of hydrogen or something else with a lot less mass. Just a...

    Calculating Cable Size | Engineers Guide

    The parameters needed are the load to be served, (what is amperage, wattage, horsepower, etc...), what are the load characteristics, (is it a motor, resistive load, etc...), what is the voltage at which the load operates and what is the distance from the source to the load. There are code...

    Do real circuits need to be physically grounded?

    It seems there is some confusion here regarding the grounded circuit conductor, (neutral leg), and the equipment grounding conductor, (earthed conductor). The "particularly hazardous" system Bob S described seems to be the standard 208Y/120V, 3ph,4 wire system we design into every building we...

    Which voltage option for single phase supply?

    Well your system in the UK is probably a 220/380Y, 3ph, 4w, system correct? Your single phase power supply has both Voltage connection options? If so, then using the higher Voltage would allow you to use smaller conductors and equipment, except that the 380V option would require a 2 pole...

    Connecting 460V Motor to 480V Supply - Issues & Risks

    XPTPCREWX, 460 Volt motors are designed to operate on a 480V system. All motors have Voltage ratings slightly below the system Voltage rating. Throughout the industry, at all Voltage ranges. Oh, and by the way Volts, Voltage, and 460V are ALWAYS capitalized. It is a proper name. Just...
