Understanding 5.5 Volt Electrical Readings
[ad#block]Electrical Voltage: Where is 5 volts coming from?
- I am changing receptacles on appliance circuit.
- I turned off all the circuit breakers for the kitchen area, 2 appliance circuits, 1 disposal +range hood circuit.
- I still show 5.5 volts at the #1 appliance hot line to the circuit breaker.
- Where is that voltage coming from?
This electrical question came from: Bruce, from Phoenix, Arizona.

Thanks for your electrical question Bruce

Residual Electrical Voltage Readings
- Bruce, the 5.5 volt reading that you are seeing is most likely residual voltage that is being fed back through the neutral wire through inductive type devices that are connected to the electrical system which is then showing up on the line at the circuit breaker that you are testing.
- One way to prove this would be to unplug or disconnect any inductive type loads and the 5.5 volt reading should disappear. Inductive loads would include motors, transformers, even incandescent light bulbs, basically anything that would have a circuit path within the internal components of the device which could induce the current or permit a current path to flow between the hot and the neutral conductors of the circuit.

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical TesterThis is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet TesterThis is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring. It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire CutterMy absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires. This handy tool has multiple uses: The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.. The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use. |
