    First off... hello everyone. My name is Nicholas. I am having a persisting electrical issue in my apartment. Way back in the Summer of 2016, my neighborhood experienced two blackouts. One that lasted a few seconds and a few weeks later, another that lasted around 15 hours. The second one took...

    I have recently moved into a newly renovated apartment and the air conditioner was not working. After testing the receptacle with a multimeter it is 240V and there is no ground installed, and the unit is 115V. After discovering this I tested some other receptacles and about half don't have a...

    I need a strong voltage regulator that is used to regulate the voltages coming out of a continuous DC generator. Four poles of high current currents that connect with the thermometer to output a 24 volt voltage to the load. Control by magnetic coil files controlled by an automatic voltage...

    Hi there I have a customer that has acquired a 3ph Icecream Batch freezer - Carpigiani LB502 So far they have installed a 10hp Rotary Phase converter to generate 3ph from the 1ph service. The customer wants to make sure the batch freezer is getting the right quality of hydro to make sure it...

    Hello.. I am curious how or why there is a higher amp draw on an induction motor during an under voltage condition. According to ohms law, isn't amperage directly proportional to voltage? I am just confused and can not seem to find the correct answer to help me understand how or why this works...

    I have a situation where I had a 1/3hp fan motor fry, when I went to replace the motor, which is powered by a 120 volt circuit which also powers a 120v circulating pump, I discovered that my volt meter reads 139 volts from live to ground, and about 40 volts from neutral to ground, but accurately...

    :detective:I have a basic voltage characteristics question I'm having trouble getting a clear answer for. In a basic 120V single phase ckt you have the hot and neutral connected to a load such as a light bulb. With the bulb burning I place a clamp meter around the hot wire and get a reading of...
