Ok simple its not because Ive been searching for answers all over the internet. I have a valid piece of OOC equipment related to this but the question is basic electronics.
The question is on an AC electromagnetic coil hooked to 120V AC if you supply power to one end and a neutral to the other you are in fact shorting that AC to neutral or ground in order to generate current flow. Is the inductance created by the flow of current through the coil enough resistance to prevent a direct short to ground or will this trip the breaker? Does there not need to be some kind of load in this crkt to prevent a direct short or is the coil enough of a load?
With an AC electromagnet....in this case a magnetic coil that actuates a plunger that releases a brake so a motor can turn. It is a three phase 480 volt motor. I realize that to create magnetic force current must flow through a coil. If I have 4 terminals on this coil, and two wires coming from the motor (2 240 volt phase legs making the 480 volt power to the coil on the terminals 1 and 2 and terminals 3 and 4 are wire nutted together, How can this possibly work with no possible current flowing through it. I am thinking I need to ground the center two terminals to produce current flow however 480 to ground is a direct short unless the coil itself will limit current flow via inductance..... If you can shed any light on this I would be forever in your debt.
