What is a short circuit? Why do appliances have ground wires? In this episode of Repair and Replace, Vance explains the fundamentals of appliance circuits. You'll learn about the differences between an open and closed circuit, short circuits and ground faults. Understanding how circuits work will help you troubleshoot why an appliance isn't working properly.

I want to make sure I am understanding correctly: if you have a ground fault after a load and your system is ungrounded, wouldn't this be a potentially dangerous scenario since your appliance would be working but if you made contact with the housing you could be electrocuted? You would have no way of knowing there was a fault in the first place. Is this correct?

@AmreSupply 8 ай бұрын

Thanks for watching. Yes that is why the ground wire is connected to the metal frame to reduce the chance of a shock. It can be difficult to see if there is a fault, but you can test to see if there is continuity to ground. You can see an example of testing for a short to ground in this stove troubleshooting video: kzfaq.info/get/bejne/oplpqbKfzdfSmJs.html

Hello sir , how much minimum resistance required to avoid short circuit in 220 AC Volt

@AmreSupply 2 жыл бұрын

Thanks for watching. A short is any unintended connection and will generally have a resistance near 0 ohm for several seconds. Regardless for a circuit to not overload you'd have to consider the what the wiring in the circuit is rated for. If you have a 220V circuit with wires rated for 15 amps, then it can handle a max of 14 ohms. You can plug these numbers in yourself in this calculator: www.rapidtables.com/calc/electric/ohms-law-calculator.html

. What will be the voltage between ground and neutral according to safety norms >n 220v.systems.

@AmreSupply Жыл бұрын

Thank you for watching. There should be no voltage between ground and neutral. If there is, then that means that there is an issue with the wiring.

When an appliance cord is plugged into an outlet, even if the switch is off, does the current flow through the cord up to the switch? If so, would this mean there is some current in the wire and it'd be possible to have a short even with the switch off? Thank you

@AmreSupply 2 ай бұрын

Thanks for watching. Current only flows when a circuit is completed. The hot wire will have a potential difference or voltage, which is the pressure that will push the current through the wires when the switch is completed. There can be a short even with the switch is off if one of the wires is compromised and is touching the metal housing or another wire. This video describes some of the concepts of electricity in more detail it's a good watch as a review: kzfaq.info/get/bejne/qMWdnMqU2cfDeac.html

Added note. Do amp draw on the circuit. Breakers and GFCI do wear out. knowing amp draw will direct you in what might be at fault. Also, Breakers and GFI are not the same. With breaker, you can get electrocuted as with GFI you should not.

Thanks for watching. In that example we checked for a short circuit between the element wire that runs inside, and the insulated metal housing. There should be no continuity between those two. The outside of a coiled electric heating element is not connected to the circuit. This is to prevent someone from being shocked if they accidentally touch the burner.
