Electrical Crackling Noise from Surge Protector

Troubleshooting a Surge Protector and Electrical Crackling Noise: How can I locate the source of an electrical crackle noise?


Electrical Crackling Noise
[ad#block] Electrical Question: How can I locate the source of an electrical crackle noise?

  • When moving around my surge protector, I noticed a crackling noise. I was not sure if it was coming from the Surge Protector or the electrical outlet.
  • A member of my building’s maintenance staff said he thought this noise could be coming from the ultrasonic pest repellent I had plugged into the wall.

Thanks for your assistance!

This electrical wiring question came from Joseph in Wurtsboro, New York.

Additional Comments: The website looks very comprehensive. I intend to use it as a reference, and I’ll recommend it to other people.

Thanks for your great electrical question Joseph.

Surge Protector Crackling Noise

Application: Troubleshooting an Electrical Crackling Noise.
Skill Level: Intermediate to Advanced – Best performed by a Licensed Electrician.
Tools Required: Basic Electricians Pouch Hand Tools, Voltage Tester or Volt Ohm Meter or plug-in circuit analyzer.
Estimated Time: Depends on the age of the home and the condition of the electrical wiring.
Precaution: Identify the outlet circuit at the electric panel, turn it OFF and then Tag it with a Note before performing any wiring inspections or electrical repairs. If an outlet or the electrical wiring is found to be damaged then repairs and replacement parts should be obtained with the same voltage and amperage rating.

Troubleshooting a Surge Protector and Electrical Crackling Noise

IMPORTANT:
The following electrical components should be inspected to locate the source of an electrical crackling noise:

  • Surge Protector
    • Over time with long periods of use a surge protector may become faulty and need to be replaced.
    • Look for discolored areas on the surge protector enclosure or a melted area around one of the plug prongs.
  • Electrical Outlet
    • Wall outlets may become faulty as well and require replacement.
    • One indicator of a faulty outlet would be a burnt or discolored area of one of the outlet slots.
  • Ultrasonic Pest Repellent
    • A ultrasonic pest repellent typically emits a high frequency noise, or a random clicking noise, but be sure to inspect this device for any visible electrical component problems.

WARNING: POSSIBLE FIRE HAZARD

Potential Hazards May Extend from an Electrical Crackling Noise

  • Potential Fire Hazard from an Electrical Failure.
    • An electrical buzzing sound may be from deteriorating electrical components.
    • Heat is often produced from an electrical failure.
    • Overheated components may result in a fire.
    • Burnt or damaged electrical circuit wiring components or a damaged surge protector unit should be replaced with new electrical parts or materials of the same voltage and amperage rating..

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This 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 Tester
This 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 Cutter
My 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.
