If half the house lost power when your circuit breaker didn’t trip, the culprit could be several different factors. These include a partial electrical outage, a failed utility power line, a bad main breaker, or even a loose connection in your electrical panel box. Essentially, one leg of your home’s electrical service stops working while the other one continues to supply power to your home.
This issue is common in Northeast Ohio communities where heavy snow, ice storms, strong winds, and summer thunderstorms can affect power. While some causes are relatively simple to deal with, others can become dangerous fire hazards if they’re not addressed promptly.
What Causes Partial Power Loss in a House?
Most modern-day homes have a split-phase electrical service from their utility company. Your electrical panel box essentially uses 120-volt power lines to distribute electricity throughout your entire home. If one of these power lines fails, power will go out in one area of your house while others remain functional.
- Some lights and outlets work while others don’t
- Large appliances suddenly shutting off
- Flickering or dim lights
- Certain rooms losing power entirely
- Electric dryers or ovens not heating properly
With a partial power outage, the affected areas depend on how your electrical panel circuitry is arranged. For some homes, you may lose all your large appliances, while in others, it may be a mixture of your lights, outlets, and appliances.
Utility Company Problems Are a Common Cause
In places like Cleveland, Akron, Canton, and Mentor, ice accumulation, fallen tree limbs, and lake-effect snow can all damage transformers and incoming power lines. If one incoming power leg from the utility company fails, your home may still receive partial power.
It’s common for your neighbors to also experience things like partial outages and flickering lights. If this happens, contacting your utility provider is the first step.
Loose Main Electrical Connections
Another potential cause of power out in part of your house is a loose or damaged connection at your electrical meter, main panel box, or service cable. Electrical connections can loosen due to things like moisture, corrosion, vibration, and temperature changes. With Northeast Ohio’s freeze-thaw cycles, this can accelerate the wear and tear on older electrical systems.
When one main connection begins to fail, part of your house may lose power intermittently. Loose connections can become a serious fire hazard and should be inspected immediately by a licensed electrician.
Problems With the Main Breaker or Electrical Panel
When you experience half of your house losing power, it’s common to check your circuit breakers. You may notice that many of the circuit breakers aren’t tripped. However, the problem could still involve your electrical panel. Older homes throughout Elyria, Lorain, and Youngstown have aging electrical systems.
Sometimes the main breaker for one side of your incoming power could fail. Even if the breaker itself says that it’s on, it may not be supplying power. Panels that are exposed to rust, moisture, and years of overheating are more vulnerable to this failure issue.
A Tripped GFCI Outlet Can Shut Off Multiple Areas
Sometimes the issue may be something simple that’s easy to overlook, like a tripped GFCI outlet. When your GFCI outlet trips, it can disable multiple outlets or portions of a room without affecting the breaker panel box. GFCI outlets are commonly found in bathrooms, kitchens, basements, garages, and outdoor spaces.
In most homes, a GFCI outlet will protect several additional outlets downstream on the electrical circuit. Issues like moisture, temporary electrical fluctuations, and humidity can all cause a GFCI outlet to trip. It can be helpful to examine the different GFCI outlets in your home to see if they’ve tripped. If you do find a tripped GFCI outlet, hit the reset button to see if it restores power to your home.
