Why am I only getting 120 volts from a 30 amp breaker that should be feeding 220 volts?
I assume you have a 30 amp two pole 220 volts breaker. Check the voltage source. If the source voltage is 220V, but out let voltage is 120 then the breaker must be faulty, a high resistance or partial open circuit could have caused the reduced voltage at the breaker outlet.
When connecting a mains polarity test between the neutral and earth connections what should the reading be?
Infinity
How do you identify that in the system the neutral is floating or not?
do a continuity test between the neutral and the metal enclosure of the equipment containing the neutral. infinity reading [ open line ] indicates floating neutral. Steve sorensen jr
How do you test a mower battery?
Same as any other 12 volt battery. Test it with a DC voltmeter. 12.6 volts = 100% charged 12.4 volts = 75% 12.2 vlots = 50% 12.0 volts = 00%
What should the reading at the light switch be when the switch and the light fixture is removed. I had a dimmer switch on that light it went out I checked the volts at the switch they were about 14?
On the "hot"wire that comes from the breaker panel the voltage should be from 115 to 120 volts. This is taken from the "hot" wire to either the neutral or the ground wire. If its not then you have a breaker problem or you are on the wrong scale of the test meter.
Is AIMS test the same as SAT test?
No, they are not the same. The two tests are administered by different agencies and the SAT contains math, critical reading, and writing.
What are the results of a voltmeter test of a battery and its state of charge?
A fully charged battery will show 12.6 volts if the car is not running. If it's running it will show between 13.5 & 15.5 volts. You will need a digital DC volt meter to test it. A reading of 12.4 V indicates the battery is at 75% charge 12.2 volts and it is at 50% charge 12 V indicates it is at 25% charge.
How do you test 220 volts using a volt meter?
Make sure that the test meter is on the correct voltage scale. Place one lead on one of the conductors to be tested and the other lead on the other voltage source conductor. The reading you obtain will be the voltage potential between the two conductors.

How do you test the charging system on a 83 kz1100 a model?
You can use a multi meter and connect it to the battery and set it for like 20 volts dc. Crank it up and see what it's reading. It should read about 13 volts or more. You can turn on the lights and see if it still reads the same. It should. If it's lower than 13 I would assume that it's not charging properly.
When you checked voltage across the leads of a 480v lighting circuit you got 0 volts but checking it to ground you get 278 volts on each leg Why?
The voltage that you are getting to ground (278) is the star point voltage of 480 volts. If you are getting zero volts from the neutral to phase leg then the neutral is open. Check back through the connections back up to the fixture. A wire nut could have dropped the neutral connection wire somewhere in the circuit, most probably at the last junction box. The reason that there is a reading to ground is that the star point is grounded at the transformer and there is no way the ground can be open as it is a continuous system with no splices.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 does kv stand for in a dielectric test?
Kilovolt or 1000 volts. 1KV is 1000 volts, 2KV is 2000 volts. Kilo stands for 1000.
