Electrical Panel Shutoff & Breaker Reset
Your Electrical Panel: What Every Portland Homeowner Should Know
Your home's electrical panel, sometimes called a breaker box or circuit breaker panel, is the central hub that controls power to every circuit in your house. Knowing how to safely shut off the main breaker during an emergency, and how to handle a tripped circuit breaker, are two of the most valuable things a homeowner can understand.
Whether you're facing a power emergency, preparing for home maintenance, or just want to be ready before something goes wrong, this page is here to help. Use the video guide below or scroll down for a quick overview of the two most common panel situations homeowners encounter. And if anything feels unclear or you'd rather have a professional handle it, Sun Glow's licensed electricians are ready to help anywhere in the Portland metro area.
Watch: Electrical Panel Safety for Homeowners
This short video walks you through how to locate and safely shut off your main breaker, and how to identify and reset a tripped circuit breaker. It's a great resource to bookmark and share with everyone in your household.
Two Things to Know Before You Ever Need Them
The two scenarios covered in this guide, shutting off your main breaker and resetting a tripped breaker, are things most Portland homeowners will encounter at some point. The video above walks through both in detail. Here's a brief overview of what each involves so you know what to expect.
These references are meant as general awareness guides. For detailed step-by-step instructions, please watch the video above. If you're ever uncertain about what you're seeing in your electrical panel, stop and call a licensed electrician. Electrical panels carry live voltage even when the main breaker is off, and safety always comes first.
Always ensure your personal safety by making sure you and the surrounding area are completely dry.
To Shut Off Power in an Emergency
- Locate the Main Power Shut Off: The large switch inside this panel (usually at the top) or outside near the electrical meter.
- Push the switch firmly to the OFF position.
- Leave the breaker OFF until the issue is inspected.
- Call Sun Glow for Service by a licensed electrician. Unauthorized repairs may be unsafe and cause further damage to your home.
How to Fix a Tripped Breaker
- Locate the tripped breaker inside this panel. It will appear not fully “on,” either sitting in the middle position or in the “off” position.
- Reset the Breaker. Push it firmly to the “off” position and then back to the “on” position.
- Overloaded Circuit: If the breaker tips again, unplug an appliance, it may be overloaded.
- Call Sun Glow for a recurring tripped breaker. Do not repetitively reset a breaker, this signals a problem.
Important safety note: Even with the main breaker in the OFF position, the utility lines entering the top of your panel remain energized. Never touch the wiring at the top of the panel. If you're ever in doubt, call Sun Glow at 503-253-7789 —we're here to help.

Electrical Panel Questions from Portland Homeowners
These are some of the most common questions we hear from homeowners in Portland and the surrounding area. Don't see your question? Call us at 503-253-7789 we're always happy to help.
Is it safe for a homeowner to turn off the main breaker themselves?
For most homeowners, yes flipping the main breaker to the OFF position is a task you can do yourself. The main breaker is designed to be accessible for exactly this reason. Watch the video above for a clear walkthrough. That said, if you see scorch marks, smell burning, or notice anything unusual near your panel, don't touch it, call a licensed electrician right away. Sun Glow serves Portland and Multnomah County and can often get to you the same day.
Why does my circuit breaker keep tripping in my Portland home?
A breaker that trips repeatedly is almost always trying to tell you something. The most common causes are an overloaded circuit (too many high-draw appliances on one circuit), a faulty appliance, or a wiring issue that needs professional attention. If resetting the breaker doesn't hold, it's time to call a licensed electrician. Sun Glow's electrical team can diagnose the problem and recommend the right fix, whether that's a simple circuit repair or an electrical panel upgrade.
How do I know if my electrical panel needs to be replaced or upgraded?
Common signs that your panel may be due for an upgrade include frequent breaker trips, flickering lights, a panel that feels warm to the touch, buzzing sounds near the box, or a panel that still uses fuses instead of breakers. Older Portland homes in particular, especially those built before the 1990s, may be running panels that are undersized for today's electrical demands. Sun Glow offers electrical panel upgrades throughout the Portland metro area.
What should I do if my breaker won't reset?
If a breaker trips again immediately after you reset it, or simply won't move to the ON position, stop trying to reset it and call a professional. A breaker that won't hold is a sign of an underlying electrical problem that needs diagnosis, not repeated resets. Call Sun Glow at 503-253-7789 and we'll get someone out to take a look.
Do electricians in Portland handle electrical panel inspections?
Yes and if you haven't had your panel inspected in several years, it's a smart idea. A licensed electrician can check for outdated wiring, overloaded circuits, improper connections, and safety hazards that aren't visible from the outside. Sun Glow provides electrical panel inspections and circuit breaker services for homeowners throughout Portland, Gresham, Troutdale, and Multnomah County.
How much does it cost to repair or replace a circuit breaker in Portland, OR?
Costs vary depending on what's needed. A single breaker replacement is typically a straightforward repair, while a full panel upgrade is a larger project.
