Here’s a simple tip: Look for sagging wires, cracked or peeling insulation, or any signs of corrosion at the point where the wire connects to your house. If you spot any of these issues, don’t touch the wires. Call a qualified electrician immediately. Your safety depends on it.
The Silent Threat: Understanding Overhead Service Wiring Risks
Overhead service wiring is far more than just a wire; it’s a complete system vulnerable to a range of environmental and age-related issues. The primary function of this wiring is to deliver electricity from the utility grid to your home's electrical panel. This panel then distributes power throughout your house. When the overhead service wiring is compromised, the entire electrical system is at risk.
One of the most common problems is weather damage. Constant exposure to sun, rain, snow, and wind can cause the insulation surrounding the wires to crack, peel, and deteriorate. This exposes the bare conductors to the elements, increasing the risk of short circuits, ground faults, and even fires. Ice and heavy snow can also weigh down the wires, causing them to sag or even break, which can result in a power outage or, worse, a live wire on the ground.
Another significant risk is tree contact. Trees growing near overhead service wires can rub against the insulation, gradually wearing it away. During storms, branches can fall onto the wires, causing them to break or pull away from the house. This not only creates a safety hazard but can also damage your home's electrical system. Regularly trimming trees near your overhead service wiring is essential for preventing these problems.
Finally, age itself is a major factor. Over time, the wires and connections can corrode, loosen, and become brittle. This reduces their ability to carry electricity safely and efficiently, leading to voltage drops, flickering lights, and overheating. In some cases, old wiring may even contain outdated materials that are no longer up to code, posing a significant safety risk.

Sagging wires are more likely to come into contact with trees or other objects, increasing the risk of damage and electrical shock.
Cracked or Peeling Insulation: This is a clear sign that the insulation protecting the wires is deteriorating. Exposed wires are a serious safety hazard and can lead to short circuits, ground faults, and fires.
Corrosion: Look for signs of rust or corrosion on the wires, connectors, and the point where the wires attach to your house. Corrosion can weaken the wires and connections, reducing their ability to carry electricity safely.
Flickering Lights: Intermittent flickering lights or dimming lights can be a sign of voltage drops caused by damaged or corroded overhead service wiring.
Burning Smell: A burning smell near your electrical panel or overhead service wiring is a serious warning sign that should be investigated immediately. It could indicate that the wires are overheating or that there is a short circuit.
Visible Damage: Any visible damage to the wires, connectors, or insulators should be addressed immediately. This includes cracks, breaks, or other signs of wear and tear.
Audible Sounds: Buzzing or crackling sounds coming from your overhead service wiring can indicate loose connections or arcing, which is a fire hazard.
If you notice any of these warning signs, it's important to take action immediately. Do not attempt to repair the wires yourself. Instead, call a qualified electrician to inspect the wiring and make any necessary repairs.
