When your power goes out and comes back on by itself, it’s not just annoying — it can be a warning sign of a deeper electrical problem. Homeowners often notice lights flickering, appliances shutting off, or entire circuits losing power for a few seconds before restoring.
While some causes are minor, others can indicate dangerous wiring issues or failing electrical components. In this guide, we’ll break down the most common reasons your electricity cuts in and out — and when it’s time to call a professional.
If you're in the Seattle or Puget Sound area, you can request service online or speak with a licensed electrician for fast diagnosis.
What Causes Power to Go Out and Come Back On?
Intermittent power issues are usually caused by unstable electrical flow somewhere in your system. Here are the most common causes homeowners experience:
- Loose electrical connections – One of the most common and dangerous causes. Loose wiring can interrupt power and create heat buildup.
- Overloaded circuits – Too many devices on one circuit can cause temporary shutdowns.
- Failing breakers or panel issues – A worn breaker may not trip properly but still disrupt power flow.
- Utility service problems – Issues from the power company can cause brief outages.
- Damaged wiring – Aging or damaged wiring can cause inconsistent electrical flow.
If your issue involves flickering lights along with power loss, see our detailed guide on lights flickering in house causes and fixes.

Yes — in many cases, intermittent power loss can be a sign of a serious electrical hazard.

When It Might NOT Be an Electrical Problem
Not every intermittent outage is caused by your home’s wiring. In some cases, the issue may be external.
- Power grid switching or maintenance
- Weather-related interruptions
- Transformer issues in your neighborhood
A good way to tell is whether your neighbors are experiencing the same issue. If the problem is isolated to your home, it’s likely an internal electrical issue.

Frequently Asked Questions
Power going out and coming back on is usually caused by a loose electrical connection, a failing breaker, or an issue with your utility service. These interruptions happen when the flow of electricity is unstable and temporarily disconnects before restoring.
Yes, intermittent power can be dangerous. It may indicate loose wiring or failing components that can overheat and create a fire risk. If you notice burning smells, buzzing sounds, or frequent outages, you should stop using the circuit and have it inspected.
Yes, loose wiring is one of the most common causes of power cutting in and out. A loose connection can interrupt the electrical flow and may also create heat or arcing, which increases the risk of damage or fire.
This usually happens when there is a problem on a specific circuit, such as a loose outlet connection, a damaged wire, or a failing breaker. Because multiple outlets and lights are connected on the same circuit, one weak point can affect the entire area.
You should call an electrician if the problem happens repeatedly, affects multiple areas, or is getting worse over time. Immediate inspection is recommended if you notice flickering lights, buzzing sounds, or any burning odor coming from outlets or your panel.
Power Going Out and Coming Back On? Don’t Ignore the Warning Signs
If your power keeps going out and coming back on, it’s usually a sign of an underlying electrical issue that needs attention. Problems like loose wiring, failing breakers, or damaged circuits can cause intermittent power loss and may worsen over time if left unresolved.
Homeowners often notice related symptoms such as flickering lights, outlets not working in one room, or even situations where half the house loses power. These issues are often connected and point to instability somewhere in your electrical system.
In some cases, the problem may be external, but if the issue is happening only in your home, it’s best to have it inspected by a professional. You can also learn how to tell the difference in our guide on power outage vs electrical problem.
