To test for resistance in a circuit should be energized or de-energized?
To test for resistance in a circuit, the circuit should be de-energized.
What will happen if a phase and neutral test by a mutimeter shows continuity?
If the test shows that there is a continuity between the phase leg and the neutral with no load connected, then that circuit should not be energized. If the circuit was energized then the fuse or breaker protecting that leg will trip the circuit open.
How do you test for fluctuating line voltage in the electrical supply to a motor?
This depends on whether the voltage is AC or DC but an oscilloscope is the tool of choice for seeing voltages and how they change with time.
What is electrical motor type test?
test in lamp
Is electrical and electronics engineering discipline eligible for air force common admission test?
Yes electrical and electronic engineering discipline is eligible for air force common admission test.
What are the inspections and test you will carry out on an electrical installation?
Different countries have different regulations about electrical inspection.
To test for resistance in a circuit should be energized or de-energized?
To test for resistance in a circuit, the circuit should be de-energized.
What items of equipment should be used to test if the electrical circuit is live?
The most important piece of electrical safety equipment that is used in the electrical trade is a voltage detector. You never start or do anything to a circuit until the circuit is tested and confirmed de energized. Once the circuit is confirmed de energized pad lock it in the off position and keep the key on your person. Never ever take any ones word for it that the circuit is turned off. Get the meter out and confirm that the circuit is de energized for yourself.
What does 'live components' mean?
It refers to an energized component. Or anything with an electrical cuerrent running though it. Good way to test if current is flowing is licking the "live component". (ps not really advisable.)
How do you wire dedicated circuits and test for that?
Dedicated circuits are ones that originate at the power panel and supply power to a pre-determined device(s). You test them with a multimeter, or other such electrical test equiment.
Which of the followig tests must be preformed on a de-energized circuit?
power test
Can a 3 pole mcb be used in a household supply and if so how?
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

What's the first test that should be carried out when working on a excisting electrical system?
1: Identify sources of supply 2: Isolate 3:Secure isolation 4:Test the voltage tester 5:Test the equipment is dead 6:Test the voltage tester 7:Begins work
What is electrical motor type test?
