To shut off the electrical power to your entire house, locate the main electrical panel (it pays to know where this is before you need it!) and flip the main circuit breakers at the top (usually a pair) to OFF. To shut off the power to individual rooms or circuits, shut off the branch circuit breakers.
Is it OK to turn breakers on and off?
A circuit breaker takes a little damage whenever you turn it off and on again. This means that while shutting it off once in a while isn’t an issue, repeatedly flipping the switch can harm it and cause an electrical hazard.
How do I know which circuit breaker to turn off?
Solution: Head out to the main electrical panel, open the outside cover and there you see 20 – 30 or more circuit breakers. Don’t panic, on the backside of the panel cover there is a list by number of the breakers. Next to each breaker number is a description of each circuit and what it controls.
Can you lose electricity one room?
Why Is the Power Out in Just One Room? Tripped breaker: The localized outage could be caused by a tripped circuit breaker. This can happen if a circuit is overloaded or has been spiked by a defective appliance. Unplug all of the appliances in the room, and check your breaker.
Where is the main circuit breaker located?
The main circuit breaker is a large breaker usually located at the top of the panel but sometimes near the bottom or along one side. It controls all the power of the branch circuit breakers (the breakers controlling individual circuits) in the panel.
How many times can a breaker be turned on and off?
Not many. Circuit breakers are designed as circuit protective devices. They are_not intended for use as everyday switches. Dependent on load when operated a circuit breaker should tolerate 50 – 100 operations after which you may be in trouble.
How do you turn your power back on after it’s been shut off?
Reset the main breaker by turning the switch off and on two times. Leave the switch in the on position. Return to the breaker panel inside your home and turn each breaker back to the on position, one by one. In many cases, power is now restored.

How to Shut the Power Off Before the Breaker Box for Safe Troubleshooting Step 1: Turn Off and Unplug All Appliances in Your House. Step 2: Locate the Main Breaker. Step 3: Turn Off the Main Breaker. Step 4: Turn Back On the Main Breaker.
How do I turn off my electric meter?

Why do I only have power in half my house?
Well usually when “half” of something dies in residential electrical, it means one hot leg is down. This could be an issue at the transformer, the wiring to your meter, the meter itself, the wiring from the meter to your main panel, the main breaker or a fault within your panel.
Why is half my electricity out?
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. Then, locate your circuit breaker panel, formerly known as your fuse box (often in the basement or garage, or in the back of the house).
Can I flip the main breaker?
The main breaker will be the largest breaker in the panel. To reset the breaker be sure to flip to the OFF position, then to the ON position. A good rule of thumb is to repeat this step TWO times. If your breaker continues to trip, please contact a licensed electrician.
What should you not touch in a breaker box?
Stay away from the large wires and lugs. They’re always live, even with the main breaker (service disconnect) shut off. If you touch them, you could die. Cover the live areas with a cardboard shield to prevent accidental contact while adding a circuit.
What is the 6 breaker rule?
The “six breaker throw rule” was a requirement in the National Electrical Code that a service must have have a main disconnect that shuts off all power and it cannot take more than six switch throws to do it, and the main disconnect(s) also must be clearly marked, as in the photo above.

Can you get shocked if light switch is off?
No! Absolutely NOT safe. You don’t know how it has been wired up. It might have had the main wire come to the light socket first, and loop around to the switch so that there are live wires in the box even with the lightswitch off.
What happens if you trip a breaker too many times?
Often a breaker that has tripped multiple times does so under an overload (not short circuit or ground fault) condition. If this happens several times in a short duration, such as a matter of hours, the temperature of the internal components can become very high.
Can a breaker trip too many times?
“In actual application, high fault levels are extremely rare (less than 2% of all faults). Molded case circuit breakers can be expected to safely clear such faults many times and still be operable.” If it a maximum rated short has caused the breaker to trip more than once it is most likely time to replace the breaker.
