What You'll Learn
Locate the electrical breaker box
If you're looking to shut off the electricity to a room, you'll need to locate the electrical breaker box. This can sometimes be challenging, as breaker boxes can be located either inside or outside the home. If your home is less than 15 years old, there's a chance your breaker box is outside. Regulations in certain parts of the country require breaker boxes to be located outside so that the local fire department can quickly shut off a home's electricity supply in the event of a fire.
If you live in an area with power lines above ground, locate the service head on your home's roof, and you'll find the service panel directly below it. If you're looking for the breaker box inside your home, look for a metal panel door that swings open or a large metal box painted to blend into your home's colour scheme. It's usually somewhere near the electric meter, either inside or outside. It may be in the basement, garage, utility closet, or hallway. If you live in an apartment, it could be in the laundry room.
The breaker box is usually not far from where the meter is, so look inside immediately opposite it on the main and basement levels. It may be a metal box, grey or painted to match the surrounding wall. If you still can't find it, ask your neighbour where theirs is, especially if your homes were built in the same era. Breaker boxes in housing developments are usually in similar locations.
If you're still having trouble locating the breaker box, it may be time to call an electrician. Some boxes may be difficult to find, especially if the home has been remodelled or additions have been made.

Switch all individual circuit breakers to OFF
If you need to shut off the electricity to a room, it is important to act quickly to avoid potential harm or fire. Firstly, locate the electrical breaker box, which is typically found in the basement, garage, utility room, or pantry. It is usually a large grey metal box with a panel of switches.
Before switching off the main circuit, it is best practice to turn off all the individual breakers first. This is a better choice than shutting off the main circuit breaker because it allows the rest of your home's power to remain on. These individual breakers will be labelled as 15 or 20 amps, which are the standard levels for household circuits.
To turn off the power to an individual circuit, identify the breaker controlling the circuit you want to turn off. This is usually labelled clearly, for instance, "Kitchen Countertop Outlets" or "Living Room Lights". Once you have identified the correct breaker, push the switch into the OFF position.
Before handling any wires, it is important to check that the power is off using a voltage tester. This will ensure that you can safely proceed with any electrical work.

Locate the main circuit breaker
Locating the main circuit breaker is an important step in understanding your home's electrical system and ensuring you can respond to electrical emergencies. The circuit breaker is the central component of your home's electrical system and serves as an important safety device that limits the power moving through the circuits.
The location of the main circuit breaker can vary depending on the type of residence you have. If you live in an apartment or condo, the breaker is typically placed in a common area that can be easily accessed by residents and building utility staff. It may be found in a hallway, laundry area, or basement. The breaker box in apartments and condos is usually painted to match the surrounding wall, so keep an eye out for a matte grey metal box that blends in with the wall.
For those living in houses, the main circuit breaker is often located in areas that are not commonly accessed by residents. The breaker box in a house is usually situated in the basement, garage, utility room, or even outside in specialized enclosures. Older homes may have their power mains located outside, which could be a fuse box rather than a circuit breaker box. If you cannot find the circuit breaker box inside your home, it may be located outdoors.
If you're having trouble locating the circuit breaker box, there are a few strategies you can try. First, look for where the power connects to your house from the outside. Examine the walls of your house for specialized enclosures made of metal or plastic, which are designed to protect the circuit breaker panel from the elements. You can also consult your neighbours to see if they know the location of their circuit breaker, as boxes in housing developments are often placed in similar locations.
If all else fails and you still cannot locate the circuit breaker, it is recommended to contact a professional electrician for assistance. They have the expertise and experience to help you find the circuit breaker and ensure your safety. Remember, it is important to familiarise yourself with the structure and layout of the circuit breaker panel once it is located.

Flip the main circuit breaker to OFF
If you need to shut off the electricity to a room, it is important to act quickly to prevent harm to people or property. Electricity can spark fires or cause serious harm to people, so it is important to know how to shut it off in an emergency.
First, locate the electrical breaker box, typically in the basement or utility room. This box controls all the electricity coming into your home. Inside the box, you will find rows of individual circuit breakers, which look like toggle switches, and a main circuit breaker on top.
The main circuit breaker is usually a larger switch, by itself or off to the side, and marked "Main" or "Shut Off". Before flipping the main circuit breaker to the OFF position, it is good practice to turn off all the individual breakers first. This is to avoid a power surge, which can be caused by suddenly turning off the main power and overloading the circuits.
Once you have flipped all the individual breakers to OFF, you can then safely flip the main circuit breaker to OFF. This will cut off all electricity coming into your home.
Remember, in an emergency, safety should always come first. If you are unsure about how to turn off your power, contact a licensed electrician.

Avoid touching bare metal contacts
When shutting off electricity to a room, it is important to avoid touching bare metal contacts. This is because the human body is a conductor of electricity. Touching live metal contacts can cause electricity to pass through your body, leading to serious health issues or even death.
Electricity can cause severe damage to the human body, as it interferes with the normal electrical signals between the brain and our muscles. For instance, electricity can cause the heart to stop beating properly, breathing to cease, or muscles to spasm. It can also result in burns to internal tissues along the path of the electric current, as well as external tissues at the points of contact.
To avoid touching bare metal contacts when shutting off electricity to a room, follow these steps:
- Locate the electrical breaker box: This is typically found in the basement or utility room of a house.
- Turn off all individual circuit breakers: Before turning off the main circuit or fuse, switch all the individual breakers to the "OFF" position. This helps to avoid a power surge, which can overload the circuits.
- Do not touch any live wires or exposed metal contacts: Be extremely cautious not to touch any live wires or exposed metal parts when handling the breaker box. Always assume that the wires and contacts are live until you have confirmed that the power is off.
- Use a voltage tester: Before touching any wires or electrical devices, it is crucial to check that the power is off. Utilize a voltage tester to ensure that it is safe.
- Call a licensed electrician if unsure: If you are uncertain about how to turn off the power safely or have any doubts, it is always best to contact a licensed electrician for assistance.
By following these steps and taking extra caution to avoid touching bare metal contacts, you can safely shut off electricity to a room while minimizing the risk of electrical hazards and potential harm to yourself.
