Hot-neutral is the load voltage. Voltage should read about 120 V (typically 115 V to 125 V). You measure exactly 118.5 V. Neutral-ground is a voltage drop (also called IR drop) caused by load current flowing through the impedance of the white wire.Click to see full answer. Similarly, what should the voltage be between neutral and ground? Voltage Measurement between Neutral to Ground: A rule-of-thumb used by many in the industry is that Neutral to ground voltage of 2V or less at the receptacle is okay, while a few volts or more indicates overloading; 5V is seen as the upper limit.Also Know, how can you tell which wire is open hot? How to Find an Open Hot in a House Circuit Open the door to the circuit panel and make sure that all of the breakers are on and that none have been tripped. Find an electrical outlet or see if there are any exposed electrical wires in the area. Hold the electrostatic wand to the wire or cable until the indicator light comes on or a sound is heard. Regarding this, what causes voltage on ground wire? Neutral-to-earth voltage can be caused by a number of factors, both in and around the farm. Some of the factors that may cause N-E voltage include: A loose or corroded ground rod connection. Badly rusted electrical boxes or conduit (a tube or duct for enclosing electric wires or cable).Why do I have voltage between neutral and ground?Some neutral-to-ground voltage should be present under load conditions, typically 2V or less. If the voltage is zero with a load on the circuit, then check for a neutral-to-ground connection in the receptacle, whether accidental or intentional. Reversed neutral and ground wires.
