A loose or corroded cable connection creates electrical resistance in the circuit, and that can cause momentary or permanent voltage drop throughout the system. It’s not just an inconvenience though. Electrical resistance creates heat, and in severe instances can cause arcing between the wire and its connection.
Why do I lose power when I plug something in?
The most likely cause is a tripped breaker. This can happen when the electrical circuit is overloaded, or a defective appliance or damaged cord short-circuits the system. First, you need to unplug all the appliances in the room, since one of them likely caused the safety device to blow.

What causes voltage surges?
Voltage spikes and surges can be caused by lightning, static electricity, magnetic fields, and internal changes in voltage use. The best way to protect your electronic equipment is with the use of a surge protector.
Can a bad outlet cause a power surge?
Damaged or exposed wiring can result in frequent power surges. Sometimes they can occur multiple times in a day, risking damage to home appliances and electronic devices, including outlets and switches.

How likely is a power surge?
Internal Surges
Internal power surges are the most common type. More than 50 percent of household power surges are of this variety. They may occur dozens of times every day. Most power surges are too small to be detected by the human senses and not strong enough to interrupt electrical service.
What are the signs of a power surge?
What are the Signs of a Power Surge?
- The device’s clock or lights are flashing.
- The device is off or does not work.
- There is an acrid, burnt odor around the device or power source.
- A surge protector or power strip may require resetting.
What are electrical surges?
Surges, or transients, are brief overvoltage spikes or disturbances on a power waveform that can damage, degrade, or destroy electronic equipment within any home, commercial building, industrial, or manufacturing facility. Transients can reach amplitudes of tens of thousands of volts.
What are three warning signs of an overloaded electrical circuit?
Signs of Overloaded Circuits
- Dimming lights, especially if lights dim when you turn on appliances or more lights.
- Buzzing outlets or switches.
- Outlet or switch covers that are warm to the touch.
- Burning odors from outlets or switches.
- Scorched plugs or outlets.
Why does my power keep flickering?
Loose wiring in electrical fixtures such as circuit breakers, wire splices, receptacles, and wall switches may reduce current flow, thereby causing lights to flicker. Loose electrical connections can cause a phenomenon known as arcing, whereby electrical current jumps across gaps.
