What You'll Learn
Identify bad wiring
Bad wiring can lead to serious damage, so it is important to be vigilant and know what signs to look out for. Firstly, if you notice any rust or corrosion near your circuit breaker, call an electrician. The wiring that connects a circuit box to an electrical system is coated in metal that should be highly resistant to rust, so any corrosion indicates a problem.
Flickering or dimming lights can be a sign of bad wiring, especially if the flickering is frequent and noticeable. This can be caused by loose cables disrupting the power connection, which can lead to arcing and sparking, and eventually, electrical fires. If you notice any buzzing or crackling sounds accompanying the flickering lights, this is another warning sign.
If you feel any heat or vibration coming from outlets or walls, this is a sure sign that there is an issue with the wiring. You can use a wire scanning tool such as the NF-826 to locate the problem without needing to call an electrician. Alternatively, the NF-820 can be used to detect hidden wires and underground cables, and it can locate power wires with high voltage without burning.
Other warning signs of bad wiring include smoking appliances or outlets, burning smells, scorch marks, and frayed wires. If you suspect any issues with your wiring, it is important to act quickly to prevent any potential hazards.

Reset tripped breakers
Resetting a tripped breaker is a relatively simple process. However, if the breaker trips repeatedly, it's best to contact a professional electrician for assistance.
First, locate your circuit breaker box and open the cover. The electric service panel is usually a metal box with a door, which may be inset in a wall, flush with the wall, or surface-mounted. Places to look include the garage, closet, pantry near the kitchen, basement, mudroom, and hallway leading to the garage or backyard.
Once you've located the tripped breaker, flip it to the "Off" position. Then, flip it back to the "On" position. You should hear a click as the breaker resets. If the breaker trips again, or simply won't reset, there may be a problem with your wiring, or the breaker itself could be malfunctioning.
If the breaker trips immediately, try unplugging some things on the same circuit, then reset the breaker again. If the breaker holds, you likely had an overload. Move the things you unplugged to a new circuit. If the breaker keeps tripping or you notice it trips after plugging in a certain appliance, it's likely a wiring issue, and you should call an electrician.
Breakers that are not in use are safe to leave off until needed.

Check for loose connections
If you're experiencing issues with your electrical connections, it's important to check for loose connections. This can be done by first determining the extent of the problem. If the power is out in your entire house, check if your neighbours also have no power, as this may be an issue with the utility company's electrical supply. If the problem is isolated to your home, it's likely an issue with your home's electrical system.
Next, you can start checking for loose connections. If a light won't turn on, try replacing the bulb. If that doesn't work, remove the switch cover and look for loose wiring. Be sure to turn off the switch before you do this. If you find loose wiring, carefully tighten the screw terminals down onto the wires. If there is no loose wiring, try testing the wires connected to the fixture with a voltage tester. If the tester shows power, the fixture itself is faulty.
If you have a frequently tripped circuit breaker, this could be a sign of a deeper problem with your home's electrical wiring. In this case, it's recommended to have a professional inspect your electrical system. However, if your circuit breaker hasn't tripped, you can still check for loose connections. Remove the outlet cover and use a flashlight to carefully examine the screw terminals where the wires are connected. If you find any loose connections, carefully tighten them. If you find that the wire connections are made via push-in fittings, consider removing them and reconnecting the wires to the screw terminals.
Additionally, you can check for other signs of bad wiring, such as burning smells, scorch marks, or vibrations at electrical outlets. If you notice any of these warning signs, it's important to contact a professional electrician to address the issue.

Replace faulty fixtures
If you are experiencing problems with your electrical connections, it is likely due to either loose or bad connections. Loose connections can be tightened, but only if necessary and only using a torque wrench with the correct values recommended by the manufacturer. Bad connections, on the other hand, should be uninstalled, cleaned, and replaced before being reinstalled.
If you have identified a faulty fixture, it is important to replace it. Here is a step-by-step guide to replacing a light fixture:
- Check your electrical circuit panel to locate the circuit breaker control for the room you'll be working in.
- Switch the circuit off and use a circuit tester to verify that the power is off.
- Place the wall switches for the fixtures in the off position.
- Remove the cover of the old fixture and the old wire connectors, and untwist the fixture's wires.
- Check the electrical box in the ceiling where the fixture is attached. Ensure that it is compatible with your new light fixture and securely attached to the building structure.
- If the box is loose, tighten the screws, but be careful not to overtighten.
- If there is no ground wire in the box, you may need to run one to meet the electrical code. This should be done by a licensed electrician.
- Fold the wires into the electrical box or the empty space in the base or canopy of the fixture.
- Attach the fixture's base or canopy to the electrical box using the included hardware.
- Install the recommended bulbs, ensuring they are the correct wattage.
- Turn on the circuit's electrical panel and then the new fixture's light switch.
- If the light doesn't come on, turn off the switch and circuit and check your wiring connections.
- Attach the trim and cover to your light fixture.
If you are unsure about any part of the process or have concerns about the compatibility of your home's wiring with the new fixture, it is best to contact a licensed electrician.
