The correct wiring and configurations of an outlet are critical for the building’s occupants and equipment. Homeowners use more appliances today that require stable electrical current to avoid damage and accidents. In this article, we outline how to test if the outlet is faulty and how to fix the issue.
Common Problems With Electrical Outlets
Your home’s electrical system is a sophisticated network of electronic components and intricate wiring. When an outlet is faulty, it can point to an underlying problem with your electrical system.
If there is no power from the outlet, it might be an issue with loose connections. The circuit breaker can trip if the outlet’s wires are not secured properly. This can increase the risk of electrocution, so you should handle them with caution.
One issue you must never overlook is a frequently tripping breaker. You can flip it back on the switch from the panel. But if it cuts off power repeatedly, it is a sign of a faulty circuit. It usually means that the outlet is drawing more power than the electrical system can deliver.
It is worth noting that overloaded electrical systems can cause overheating and short circuits. Instead of flipping back the switch on the electrical panel, have your home’s circuit tested.
Tips for Testing Outlets
Before testing, you must understand the different components of the outlet. A grounded outlet will have three pins. The taller slot on the left is neutral, while the shorter one to the right is hot. The half-circle below the two pins is the ground slot.
To test the outlet, you’ll need a multimeter with the configurations set on alternating current. Some multimeters can detect the current automatically. You could also use a voltage detector or voltmeter.
You may want to rule out faulty electronics before testing the outlet. You can use the appliances on other outlets to ascertain it is working. If you feel uncomfortable performing this test, you can call Peterman Brothers for timely electrical repair services in Indianapolis.
How to Test a Grounded Outlet
Your electrical system needs a grounded connection to prevent electric shocks and fires. The ground provides a complete path for the current to return to its source. That way, when there is lightning or a storm, the circuit breaker will cut off power instead of overloading the circuit.
Proper grounding is essential as it protects your equipment from power surges. Grounding also ensures compliance with the NEC (National Electrical Code). If you believe an outlet does not have a proper grounding, consult an electrician.
You can test the outlet for grounding by placing the red lead probe of the multimeter in the small slot. With the black tip in the ground slot, check the voltage readings. If the values are not zero, it means the outlet is not grounded properly.
The Danger of Reversing the Outlet’s Polarity
Switching the polarities of the outlet may not appear to affect incandescent lighting and some electronics. But if the outlet has the neutral and hot wires reversed, it can diminish its ability to cut off power when not in use. The appliance remains energized with electrical power even when it is off.
Since the appliance is energized, it can cause electric shocks when someone touches it. Incandescent bulbs may continue working if the polarities are in reverse. But it can be risky when screwing the bulb in place.
The metal shell of an incandescent lamp is neutral, while the contact at the bottom of the bulb is a hot wire. Therefore, the standard configuration reduces the risk of electrocution when changing bulbs. Because you are more likely to touch the metal shell, the fixture is more dangerous when the polarity is reversed.
The bottom line is reversing polarities is risky for both appliances and the building’s occupants. You can test polarities by placing the black lead into the larger slot and the red tip into the smaller one.
If the multimeter registers a reading, there is probably an issue with the polarities. You should avoid plugging any sophisticated appliances into the outlet. A certified electrician should be contacted to fix it first before you can use it. Peterman Brothers’ electrical team has vast experience handling projects of varying requirements in Indianapolis.
Preventing Accidents When Testing Outlets
Generally, an outlet will have three slots: ground, neutral, and hot. When testing the circuit, treat each slot with caution as any can carry current. Short circuits within the outlet mean that the electrical current could be from any of the slots.
To prevent shocks from going through your body, hold both lead tips in one hand. You must never allow the two metal pieces to touch. The connection will trigger a short circuit and start a fire.
Before attempting any tests, pay attention to signs of a faulty outlet. Electrical arcs can cause burns around the slots. If the fixture feels warm to the touch, that is probably a sign of short circuits. A replacement is often necessary to prevent hazards.
If the outlet has clear signs of faults, it is best to avoid tampering with it. In such cases, there is a high risk of electrocution. You could accidentally push wires together that touch, which can trigger an electrical fire.
It is also advisable to replace outlets that let the plug fall out easily. It is usually a sign of rapid wear and tear of the internal components. Electrical arcs can melt and damage the metal contacts, and exposed wires can fray the insulation.
Therefore, if the plug is falling out, it could be an electrical fault or an overloaded circuit. The best solution is to have an electrician test the outlet and rewire or upgrade the electrical system.
What to Do When You Have a Faulty Outlet
It is advisable to schedule an inspection if you suspect faults in your electrical system. Burn marks around extensions or outlets may point to an underlying issue with your home’s circuit. For example, your home may need rewiring due to outdated or substandard installations.
Older houses have an electrical circuit that cannot handle the demands of a modern home. An outdated system has elements such as aluminum wiring or inefficient fuse mechanisms that can pose safety issues. Rewiring is also necessary to ensure your home complies with the NEC (National Electrical Code) standards.
Check for rooms with only the two-pin, rather than the grounded three-pin outlet. It is often an indication that the electrical system is outdated. According to statistics, there are more than 12,500 fires annually as a result of defective wiring.
Therefore, performing inspections, replacements, and rewiring, is a good investment for the comfort and safety of your home. Faulty electrical outlets and circuits tend to waste energy. Your monthly bills can rise due to malfunctions increasing your home’s energy consumption.
