Electrical Panel Basics

A plain, friendly guide to the breaker panel: finding a tripped breaker, resetting it the right way, telling an overload from a short, and when to leave it off and call.

Start the checklist

Where to start

Lights or outlets just went out?
Look for a tripped breaker. See reset a tripped breaker.
It popped or sparked when you reset it?
Leave it OFF and call. See overload or short.
Smell burning or see smoke?
Get everyone out and call 911 from outside.

The short version

The panel sends power out to each circuit in the home. Breakers trip to protect the wiring when a circuit overheats or something shorts.

A tripped breaker often sits in a soft middle spot, not all the way OFF. Some show a small red or orange flag in a little window.

Reset it in two moves: firmly to OFF until it clicks, then to ON.

If it trips again right away, with a pop or a spark, leave it OFF and call. Panel covers, wiring and outlets are jobs for a licensed electrician.

Who does what

Every home and lease is a little different, so these are examples. When you are not sure, ask first.

Residents can often

Keeping the path to the panel clear
Finding and resetting a tripped breaker once
Spreading big appliances across circuits
Reporting a breaker that trips again

Leave to the owner or a pro

Removing the panel cover behind the door
Any wiring, outlet or breaker replacement
Finding the cause of a short or an arc fault

Reset a tripped breaker

Keep the space in front of the panel clear, about three feet, so you can reach it safely.
Open the panel door. Never remove the metal cover behind it.
Find the handle sitting in the middle, or the one showing a red or orange flag.
Stand a little to one side of the panel and use one hand.
Push the handle firmly to OFF until you feel and hear a solid click. That resets the latch inside.
Push it smoothly to ON.
If it snaps right back, stop. Leave it OFF and report it.

Overload or short?

Overload. Too many things running on one circuit at once, like a space heater and a hair dryer. The breaker warms up and trips after a little while. Unplug one and move it to a different circuit before you reset.
Short. The breaker snaps back the instant you reset it, often with a loud pop or a spark. Do not try again. Leave it OFF and call your owner, who will bring in a licensed electrician.
Arc fault breakers. Many newer panels have breakers with a TEST button. They watch for sparking in the wiring. Some have a small light that shows what made it trip. Note what you see and share it.

Your breaker panel checklist

From the guide’s own checklist. Tick each one as you go. These are examples; your home may need others.

0 of 6

Panel found, with the path in front kept clear
Breakers labeled (ask your owner)
You know what a tripped breaker looks like
Reset means firmly OFF until it clicks, then ON
Big appliances spread across different circuits
A breaker that trips right away is left OFF and reported

An everyday example

An electric kettle and a toaster were switched on at the same time on the kitchen counter. A few seconds later both shut off, along with the kitchen lights. One breaker sat in the middle spot. Moving the toaster to an outlet on a different circuit, then pushing that breaker firmly to OFF and back to ON, brought the power right back.
