Breaker Panel Inspection

Breaker Panel Inspection & Repair in League City

All electrical activity in your home begins at the breaker panel (also sometimes referred to as a distribution panel, electrical panel, or breaker box). In some homes, the breaker panel is mounted on an external wall. But in most homes, the breaker panel can be found in a guest bedroom, closet, or the attic. Your breaker panel distributes power to all the electrical outlets, appliances, and lights in your home as you use them. Should there be a malfunction or surge, modern breaker boxes have an important safety feature that cuts off electricity to the area drawing the excess power to prevent overheating, sparks, and even fire. Older panels may not include this important safety feature, which is why you should check to see if your panel is outdated or has been recalled. If your breaker panel is outdated, you should have it replaced with a new, safe panel as soon as possible.

It’s important to keep up with your breaker panel to ensure that everything is working properly. As panels age, they can deteriorate due to wear and tear or even the prying teeth of pests. If you notice black marks on your panel or a circuit that won’t reset, it may be time for an inspection. While it is completely okay for a homeowner to flip a breaker back on when there has been a power surge, for your safety we ask that you please leave all serious work and inspection to a licensed and insured professional electrician.

Rewiring Homes for Safety and Efficiency in League City

Hidden behind your home’s walls are expansive trails of wires running power from your breaker panel to every electrical component of your home. Contemporary wires ought to be made of copper insulated with a PVC plastic. While we use copper and PVC in modern wiring practices, some wiring systems found in older homes use aluminum wiring with a type of rubber or plastic for insulation. Copper provides the necessary electrical resistance to prevent wires from overheating, but aluminum wires can overheat and potentially melt their plastic insulation. Furthermore, plastic and rubber wire insulation is known to brittle over time, leading to exposed wires. Should two exposed wires touch one another, it could lead to a fire. Older wiring made of aluminum and plastic can be found in pre-1990s construction. If your home is more than 30 years old and uses its original wiring system, you may want to upgrade to newer, safer wires.

Some indicators of wiring issues in homes both new and old include flickering lights, switches and outlets that don’t work, or in some cases even the smell of smoke or a humming sound coming from behind your walls. If you notice any of these signs, call a licensed electrician to inspect your electrical system and provide you with the appropriate repair.
