You may have activated the switch to turn on the lights, but only the selected bulbs illuminated, and other lights did not work. Or it could be that when some of your kitchen appliances operate, your television screen and lights in the living room flicker abnormally. However, don’t worry; this is not a paranormal situation—it’s a partial power outage.
So, what causes partial power outages? We will clarify everything. This post also provides a step-by-step troubleshooting process to recover power and maintenance guidelines for avoiding future power outages.
What Is a Partial Power Outage?
In a partial outage, the electrical power terminates only within specific sections of a building yet operates in different sections of the same building. Unlike a full blackout, where every circuit ceases to function, during a partial outage only some circuits stop operating while others continue to receive power. This means certain devices will function, yet other electrical components will not operate. For example, your kitchen lights might be on, but the living room could be dark.
Common Causes Of Partial Power Outages
There are numerous reasons why your residence might face a partial outage. Here they are:
- Tripped or Faulty Circuit Breakers: Circuit breakers prevent electrical overloads and short circuits. If one trips, it can cut power to certain areas while others remain on.
- Overloaded Circuits: When multiple devices connect to only one circuit of an older house, it can overload the system. The instantaneous power loss in particular areas when using numerous appliances might indicate the cause of this issue.
- Utility Problems: Transformers that are damaged and power lines that fall result in electricity outages in certain areas.
- Loose or Faulty Wiring: Faulty or loose electrical wiring won’t conduct electricity properly in certain outlets and areas.
- Blown Fuses: Older housing structures containing fuse boxes can produce partial outages through blown fuses.
- Faulty Appliances: Defective appliances either trigger the circuit breakers or blow fuses, which then lead to partial electric outages.
How To Troubleshoot A Partial Power Outage?
You can solve a partial electrical power failure at home through the following procedure. Make sure you prioritize safety before going through the steps:
Step 1: Prioritize Safety
Never touch exposed wires or attempt repairs if unsure. It’s unsafe for unskilled persons to handle exposed wires because they transmit active electricity, which creates a risk of electricity shock and fire. You should contact specialists to conduct electrical maintenance whenever you doubt your ability to perform the work.
A licensed electrician will possess an understanding of legal safety codes to reduce risks. But if you’re confident or have the knowledge to fix a partial outage, you must switch off power supplies first before performing work near electricity. Also, use insulated tools together with safety procedures to minimize potential risks.
Moreover, observe local building codes regarding electrical work because they are crucial for safety measures, reliability, and adherence to compliance. These codes protect against electric shocks and avoid dangerous fires by defining requirements for circuit safety protocols and ground installation.
They also ascertain uniformity in electrical systems, which applies to all buildings. However, the majority of codes demand professional electricians to check and supervise modifications to guarantee proper execution while minimizing potential future hazards.
Step 2: Check Circuit Breakers
An electrical panel exists in the basement, garage, or utility room of your property. Then, look for breakers in the panel that display either an off status or remain between their normal positions. The circuit breakers operate by protecting an electrical system by automatically disconnecting the power supply in cases of short circuits or overload conditions.
So, the breaker that’s off or stuck may have tripped. To reset it, flip it off and then on to restore power. Turning the breaker off will disconnect power and help clear temporary issues like overloads or minor short circuits.
Switching it back on will restore the connection, allowing power to flow if the problem is resolved. If the trip was due to a temporary issue, the circuit should work normally after resetting.
Step 3: Inspect Fuses and Connections (Old Residences)
If your home is old, it will have a fuse box instead of breakers. Therefore, check for blown fuses, as this issue often occurs frequently in homes that still use old electrical systems. Too much electrical demand on a single circuit can lead to blown fuses.
But unlike breakers, you can’t reset them. So, you’ll have to replace them with ones of the same rating. Also, ascertain all connections in the fuse box are secure, as loose ones can cause a partial outage.
Step 4: Identify the Problematic Appliance
Check the affected rooms after you reset both your breakers and fuses. Examine if a defective appliance exists in the affected areas by unplugging every device and reconnecting them one at a time. An ill-functioning tool can trigger several types of power-related problems. The excess current from the device will cause a circuit breaker to activate. This cuts off the power supply to specific sections of the area while other sections continue to function normally.
Whereas in residences with fuse box systems, the fuses can explode when short circuits occur or when there is an excessive draw of electricity. Times of power loss may also occur when appliances have damaged components or wiring. What’s more, the outlet portion or the circuit itself can develop localized electrical problems due to the device plugged into it. Besides, when various devices occupy the same electrical circuit and one fails to operate correctly, it can lead to an electrical circuit breakdown resulting in breaker activation or fuse failure. If the issue isn’t caused by a faulty appliance, the problem might lie in your home’s outlets or switches, which require thorough inspection.
Step 5: Examine Outlets and Switches
Electrical trouble and partial outages emerge from outlets and switches that become loose or sustain damage. When repairing damaged outlets, it becomes critical to check for every indication of destruction, which might include cracks, burn marks, and loose electrical components. If you see any visible damage, this requires switching off power through the panel before you begin replacements.
Start by removing the outlet cover and unscrewing the defective outlet or switch while noting the wire arrangement. Trim damaged wires first and strip their ends before installing them on the new outlet. Attach the black (hot) to brass, white (neutral) to silver, and green/bare (ground) to the green screw. Finally, secure everything, restore power, and test to make sure it functions.
Step 6: Call an Electrician
Professional help from an electrician becomes necessary when all attempted solutions fail and the problem may exist in the wiring or panel components. This is because improper repairs often result in dangerous situations such as shocks and fires and additional system damage.
Thus, hiring a licensed electrician brings peace of mind by assuring both safety measures and correct compliance with local building codes. Through comprehensive examinations, a professional will detect concealed problems. To proceed, find a qualified electrician by checking reviews and recommendations. Then, schedule an inspection, discuss possible solutions, and request an estimate to understand costs before proceeding with repairs. If the issue isn’t caused by a faulty appliance, the problem might lie in your home’s outlets or switches, which require thorough inspection.
Step 7: Consider External Causes
Contact your utility provider when the issue persists because utility problems could cause a partial power outage. The external disruptions affecting power originate from various sources, including meteorological conditions, equipment malfunctions, and maintenance interventions. Customers cannot spot power distribution interruptions because problems such as transformer damage or faulty power lines are not visible to them.
Therefore, use the customer support phone number of your utility provider to report outages with your service. Get a list of required information, including your address, before contacting customer service. You can report issues through the official website, phone number application, or social media page of their company. Make sure to share with your utility provider all efforts you have made to solve the problem while requesting data about when restoration work will commence. These details can be found on their website or automatic messaging systems.
