What are the different faults occurring in the overhead transmission lines? feeders and branch circuits to the farthest outlet does not exceed 5 Can patents be featured/explained in a youtube video i.e. You're seeing voltage drop on the neutral, which since a neutral starts at 0V, tends to lift the neutral's voltage up a volt or two. 2.1No voltage showing between the Hot and the Neutral terminals in either outlets #1 or #2 of circuit D or outlet #2 of circuit C, but the multimeter would read 120 volts at outlet #1 in circuit C. 2.2A 120 Volts reading between the Hot and the ground at any of the outlets of both circuits C and D. You are likely concerned about improper wiring at this point. In a proper neutral-to-ground installation, the voltage between the 2 Why do I have voltage on my ground wire? You have a malfunctioning neutral. Also if someone made a neutral ground reverse the ground system takes back the returning current and anything bare gets heated up, I think some kid got killed in a ground neutral reverse in Australia on some 230V when he turned on the hose and got between two grounds. www.ecmweb.com is using a security service for protection against online attacks. It might have some effect on the electronic circuits but might not affect some others. short answer: its because the two, 180 degrees out of phase, feed wires essentially take turns being the return wire every time the phase switches. Ensuring that all electrical systems are up to date is a top priority for your home inspection team. How does a fan in a turbofan engine suck air in? Michael Sand. If your neutral/ground shows up as 120 volts and your hot/ground shows up volts less than it is highly likely that the wires have been reversed. Youre reading through the light bulb. If I test the ground and the neutral mid-line (at a junction box between two of the lights), I am getting 50 volts. When I connected everything the first time and turned on the power, the breaker tripped. BillW. Thats why if you look at Transient Voltage Surge Suppressor (TVSS or just a surge protector) for home use, the specs should specify the level of protection through all modes including N-G. 123 volts hot to neutral/ground is fine, likely means youre physically closer to the substation, nothing at all to worry about. 210.19 Conductors Minimum Ampacity and Size. 0000003607 00000 n The problem is not in the electrical panel if the switch was existing. If I test the ground and the neutral mid-line (at a junction box between two of the lights), I am getting 50 volts. The short could be anywhere in the circuit. Using a digital multimeter and touching the black lead to the exterior of the recessed lights and the red lead to my finger, the multimeter reads 18 volts, so basically the ground is carrying voltage to the can lights. But sometimes there exists some measure of potential difference between them. This can cause a safety hazard and the wires should be corrected immediately. Why is neutral and ground not precisely the same voltage? Often times when we have new electrical or old electrical wiring done in our home, we trust that the electrician runs every wire correctly. Your local home inspection team can determine if wires and electric receptacles, as well as light fixtures, need a change. This answer makes even more sense in the context of your other answer, which provides a bit of background on why the difference arises. I will down-vote answers which basically say: Ohm's law.

I wired 8 recessed lights to a switch in a room. How does a fan in a turbofan engine suck air in? Bonding everything (across water meters, water softener pipes, hot water heater pipes, run a bond to the gas line and at the furnace) works to equalize the ground, you get hit when there's a difference. I just had a similar problem. If this is important to you, you probably should edit your answer to make it clearer. The cookie is used to store the user consent for the cookies in the category "Analytics". Also the neutrals never are on the same bar as the ground wires in a sub panel, they must sit on a floating neutral bar, if using a regular panel tub as a sub panel you must remove the ground bonding screw from the neutral bar.so the metal panel and grounds are not touching the whites anywhere but back at the main panel. A neutral wire is a type of wire in which carries currents back to the source of power and or regular voltage. startxref As it is AC voltage Vnwrtg can be in synch or out of synch therefore can be addition or subtraction at time t and can vary.

It represents the IR drop on the neutral wire. www.ecmweb.com is using a security service for protection against online attacks. This voltage is very little to cause any adverse effect. So, for the neutral to ground measurement, you'll want half of the 3%. Under load conditions, there should be some neutral-ground voltage 2 V or a little bit less is pretty typical. BillW. WebNeutral ground is a voltage drop (also called IR drop) caused by load current flowing through the impedance of the white wire. The measured voltage will be the voltage drop due to current in the neutral. The greater the load, the likely a possibly switch has occurred. 0000000016 00000 n This makes things like lamps and many appliances more safe to operate. 0000006367 00000 n A connection from neutral to ground will not likely kill you, but a connection from live to ground stands a decent chance of doing so. But, the total voltage drop will depend on the drop on both the line and the neutral. Use multiple rods for earthing can provide a parallel path for current flow and improve the earth connection. The voltage between the two legs (called phase to phase or line to line) is 240V and the phase to neutral voltage is 120V. Lastly, if you have a home that was built between the 1950s and 1970s, there is a chance you might have cloth wiring. the following: At service equipment, the voltage difference between the neutral conductor and the service equipment case will be 0 volts. 9 0 obj <> endobj Most electrical power systems in the world use a multi-phase voltage system, to be more specifically, a 3-phase system.
