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.
What else can I help you with?
Why neutral is required?
Neutral is the current return for the hot leg(s). Neutral is grounded, so as to limit the maximum voltage of any of the hots with respect to earth ground. In a typical residential 120/240VAC split phase system, either of the hots with respect to neutral is 120VAC. In a three phase system, neutral is at the center of the wye configuration, and each of the three hots returns power to it.
How do you convert 120vac to 24vac?
You can use a step-down transformer to convert 120VAC to 24VAC. Select a transformer with a ratio of 5:1, which will step down the voltage appropriately. Be sure to follow proper safety precautions when working with electricity.
Do I have 120v electrical in my home?
Yes. In the United States, standard household voltage is 120VAC @ 60Hz. If properly installed, you can also run standard devices at 220 or 240 volts AC in the US.
In the United States is a neutral wire used in 120 VAC circuits?
Yes, in the United States, a neutral wire is used in 120VAC circuits to complete the electrical circuit back to the power source. The neutral wire carries the return current from the load back to the electrical panel.
What is 120vac 60Hz 340mA on a GE HELICAL 20W bulb?
The specification "120VAC 60Hz 340mA" indicates that the GE Helical 20W bulb operates on a standard voltage of 120 volts, at a frequency of 60 hertz, drawing a current of 340 milliamperes. This means it is designed for typical household electrical systems in North America. The bulb consumes 20 watts of power, making it an energy-efficient option for lighting.
What is the typical voltage of a control transformer for a three phase 480 volt starter?
Most 3 Phase 480V Starters are controlled by 120VAC. This is because the coils on the contactors (starters) are 120VAC. Just ensure the voltage matches the coil.

Can you use a 120VAC cable to run a 220VAC appliance?
No, you cannot use a 120VAC cable to run a 220VAC appliance. The voltage ratings of the cable and the appliance must match to ensure safety and proper functioning. Using an inadequate cable can lead to overheating, potential electrical fires, and damage to the appliance. Always use the appropriate voltage-rated cables for your appliances.
What does VAC mean?
v = volts a = alternating c = current vac is what the lights and appliances in your house use. Your TV uses 120VAC. 120vac is the accepted standard of electric current commonly used through out the U>S>. Vac speaks of ac or alternating current voltage.
What does 120 mean?
v = volts a = alternating c = current vac is what the lights and appliances in your house use. Your TV uses 120VAC. 120vac is the accepted standard of electric current commonly used through out the U>S>. Vac speaks of ac or alternating current voltage.
What does 120 vac mean?
v = volts a = alternating c = current vac is what the lights and appliances in your house use. Your TV uses 120VAC. 120vac is the accepted standard of electric current commonly used through out the U>S>. Vac speaks of ac or alternating current voltage.
What is the peak-to-peak voltage in a circuit with an rms voltage of 120VAC?
ANSWER: The peak to peak voltage can be found by multiplying 120 v AC x 2.82= 339.41
Do I have 120v electrical in my home?
Yes. In the United States, standard household voltage is 120VAC @ 60Hz. If properly installed, you can also run standard devices at 220 or 240 volts AC in the US.
Can you use a 480VAC step down transformer and apply 120VAC to the primary?
In theory, you can. If you have a power transformer rated at 480 primary side and the secondary at say 120VAC, then the ratio is 4:1. Meaning that there are four times the number of turns on the primary side as to the secondary. So, if you were to power the primary side with 120VAC as opposed to 480VAC you would expect to see a 1/4 reduction in voltage output on the secondary, or 30VAC. The current would be dependant on the cross section of the secondary conductor and core construction. As current is increased thru the load (as in resistance welding) for example, you would expect voltage to decrease or lag, a larger Industrial sized transformer is able to compensate for this lag in voltage better than a compact household power transformer.
What does 120vac or 240vac mean?
v = volts a = alternating c = current vac is what the lights and appliances in your house use. Your TV uses 120VAC and your dryer or electric stove uses 240vac. 120vac is the accepted standard of electric current commonly used through out the U>S>. Vac speaks of ac or alternating current voltage. 240 volts is simply twice that amount. Electric lights, lighter appliances mostly use 120 volts to energize them but heavier duty appliances such as dryers required more voltage as they use more energy. Vac or alternating current as oppose to DC(Direct current )which is normally used on boats, ships, etc.
How do you measure 3 phase voltage?
Three phase voltage can be measure line to line (L1-L2, L2-L3, or L1-L3) with a quality digital voltmeter. In the United States, typical 3 phase voltage is 208-230VAC, or 460-480VAC measured line to line. Line to ground or neutral with a 208-230V system will yield 110-120VAC, which provides standard household power for things like televisions and microwave ovens.
