What else can I help you with?
Why is it that when you touch the neutral in a box that is not connect to the panel cause the test light to come when touching the power wire?
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.
What you measure voltage into?
You measure voltage using a voltmeter which involves measuring the electrical potential difference between 2 points in an electrical circuit.
Why current cannot be measured directly using an oscilloscope?
A standard oscilloscope is designed to measure voltage, you need a current probe for your oscilloscope to measure current.
208 volt 12 amps versus 277 volt 6 amps?
It is hard to see a question here. Both of these voltages are currently use in electrical systems today. Both voltages are related to three phase systems. A voltage of 208 volts is a three phase wye system that has a voltage of 208 between lines L1, L2 and L3 and 120 volts between any of the lines and neutral. A voltage of 277 is the line to neutral voltage of a 480 volt three phase wye system. There is a voltage of 480 between L1, L2 and L3 and 277 volts between any of the lines and neutral.
What is voltage phase to phase 380 3 phase?
Voltage phase to phase in a 380V 3-phase system refers to the voltage measured between any two of the three live conductors in the system. In a balanced 3-phase system, the phase to phase voltage is equal to the line voltage, which is 380V in this case. This voltage is commonly used in industrial and commercial applications to power heavy machinery and equipment. It is important to note that the phase to phase voltage is higher than the phase to neutral voltage in a 3-phase system.
On a standard three prong AC outlet what should the AC voltage measure between neutral and hot?
Nominally 120 Volts.
Why we measure voltage between neutral to earth?
To ensure that it complies with the relevant electrical wiring regulations.
How do you determine hot to neutral?
How do you determine what? If you are asking how do you measure the voltage between Hot and Neutral, I suggest a voltmeter. If you are asking how do you differentiate between Hot and Neutral in home wiring, the Hot is Black and Neutral is White.
Should there be voltage between the neutral and ground?
No, ideally there should be no voltage between the neutral and ground wires in an electrical system.
Why would you get half voltage between live and neutral?
You can measure a small voltage between earth and neutral, even if the neutral is grounded to earth, because the neutral conductor acts as an antenna picking up electromagnetic radiation in the atmosphere. -------------------------- If the above answer were true, the earth conductor would also act as an antenna. But the real answer is, if you read ANY voltage between the neutral and earth, the neutral is broken somewhere between where you are measuring and the panel or not properly bonded in the panel. Call a competent electrician to repair the problem.
What is the problem if I measure voltage on an 120vac outlet 96 volts from neutral to ground?
Firstly measure the voltage between your live and earth.Assuming you get ~120 volts here, the problem is a loose neutral somewhere along the line.If you get 24volts the problem is a bad earth connection, with a fault voltage on it.TBH it's most likely the former, as the latter implies 2 separate faults.
Why do you read no voltage if one leg is still hot when you measure lead to lead?
You don't provide enough information to be certain what you are measuring. If you have a hot leg then by definition you will have a voltage between the hot leg and ground or neutral (if neutral bonded properly to ground in main panel). However, there may be no voltage between hot and some unspecified "floating" wire.
Voltage across Neutral and earth for a 3 phase auto transformer?
A grounded neutral will be at earth potential. A floating neutral will be at a voltage dependent upon the voltage imbalance between phases, and the design of the transformer.
Could a neutral wire be powered?
There should be zero voltage between neutral and ground.
What is voltage between earth and line?
In a typical residential situation there is 220 to 240 volts between the two hot wires that are typically red and black and 110 to 120 volts between neutral and either black or red. The voltage between neutral and earth should be zero.
Should there be power from common to ground in wall socket?
120 volt wall outlets. Their could me a small voltage between neutral and ground,up to around 1.5 volts. What you are measuring is the voltage drop on the system at that point in the system. You see the neutral and the ground are at the same level some where up stream (service panel). The neutral is under the same load as the phase conductor, and the neutral will drop voltage same as the phase. This is in fact the way I measure voltage drop, (neutral to ground.) However don't get fooled by high imped. meter, They have a way of ghosting a voltage. Or floating high, You get a reading but the voltage is really not their.
When phase and neutral will short means what will be the voltage in neutral?
If the phase and neutral wires are shorted together, the voltage in the neutral wire will be the same as the phase voltage. This is because the short circuit effectively bypasses any impedance or resistance in the circuit, causing the potential difference between the phase and neutral wires to be equal.
