If you touch the live conductor to ground terminal, it results into a severe earth fault between ground and live, drawing huge fault curent. The protective devices if connected in the system, will trip offf.
It is extremely dangerous to do so intentionally. Avoid this at all costs.

Is 200Mohms an acceptable result when carrying out an insulation resistance live-live test on a shower block?
If you have 200 megohms on an insulation test of a conductor it is more than enough to feel safe about applying a voltage to the conductor with out it shorting to ground.
What is the g in a megger test?
It is the terminal on the megger that the ground cable connect to when testing a device to ground.
How do you check the choke is working or not?
chock has two terminal plug in live one terminal and test another with test pen.if the test pen light the chock ok
Is humanbody a conductor or insulator?
a conductor. that's why we need to touch at the end of the test pen to check the electricity. when we touch test pen, we will complete a circuit from source to the ground through human body.visit trigyy.com for more information.
What is the procedure to test the fuel pump relay on a 1988 GMC 2500 van?
Get a test light then check for getting voltage. Ground the engaging terminal and see if you have voltage going ot the pump.
How is a circuit-powered test light used?
First make sure the test light is rated for the voltage you are working on. Don't use an automotive 12v test light in your home wiring. A simple test light has a test lead and a ground clip. You attach the ground clip to a known ground point (a bolt on the chassis of a car, or the - battery terminal). You then simple touch the test lead to the area being tested. If the light illuminates, then there is power there, if not, then there is not power there.
How do you test a substance to see if it is a good conductor?
Do a chromatography test.
What are the test for 132 kv cable?
1. phase identification test. 2. Insulation Resistance Test. 3. Conductor capacitance. 4.Conductor Resistance. 4. Outer Sheath Test.
How to wire a plug with blue brown and Black?
Test the wire with a meter to determine which wire is your hot, which is your neutral, and which is your ground. Those colors are indicative of a 240v circuit normally, so you may have two hots and a ground. Other wise Hot=Black, Neutral=White, and Ground=Green for placement. On your plug, Black/Hot goes to the brass colored terminal. Green/ground goes to the sometimes green terminal that is off by itself usually at the bottom of the receptacle. The neutral goes to the silver terminal.

How do you get rid of ground loop from a turntable?
If you mean you want to get rid of some background "hum" that is being picked-up by the signal leads from the pickup cartridge - probably from the turntable's motor - you should check the pickup's signal wiring is shielded and grounded. Usually turntables already have shielded wiring for the pickup leads so it is worth checking that none of the shielded wires have become disconnected from the Ground terminal on the turntable's baseboard or from the pickup head itself. Next check that your turntable's Ground terminal is actually connected to the Ground terminal at the back of your preamp or amp. Sometimes there is a separate Grounding wire or sometimes it is just the shield of the pickup signal wiring that does this job. Be sure to unplug everything - amp, preamp and turntable - from the household AC supply socket outlet before you do any checks. It is best to use the resistance measurement setting of a normal electrical test meter to do those ground wiring checks. The resistance measurements from turntable Ground terminal to pickup housing and from that same terminal to the amp's Ground terminal should show a very low resistance, almost zero Ohms.
How can you do the polarity test of a switch?
A 'polarity test', as it applies to a switch, is performed to confirm that the switch is located in the line conductor and not in the neutral conductor.
