Insufficient Power Supply

Moving from flickering lights, we often encounter another common issue in older homes: insufficient power supply. Our modern lives demand more electricity than ever before. Older houses typically have 100 amp service, which falls short of today’s needs.

Insufficient Power Supply

We've seen homes with only one outlet per room, forcing residents to rely heavily on extension cords and power strips. This overreliance can lead to dangerous overloads. We recommend upgrading to a 200 amp service panel to meet current power demands. It's crucial for safety and convenience. Many older homes struggle to power multiple appliances simultaneously.

We’ve found that upgrading the electrical panel solves this problem effectively. It allows for more circuits and outlets, reducing the risk of overloads and electrical fires.

Frequent Electrical Surges

Frequent electrical surges are a common headache in older homes. We’ve seen this issue pop up time and again in houses with outdated electrical systems. Aluminium wiring, often found in older properties, increases the risk of these surges.

Circuit overload and serious wiring problems can also trigger these pesky power spikes.

We can’t stress enough how crucial professional inspections are for tackling frequent surges. A certified electrician can spot potential hazards and ensure your home meets current safety standards.

Installing Ground Fault Circuit Interrupters (GFCIs) in wet areas like bathrooms and kitchens boosts electrical safety. Regular check-ups help identify and fix issues before they become dangerous.

Specific Electrical Problems

Older homes often hide electrical surprises. These issues can range from minor annoyances to major safety hazards.

Overlamping

We’ve seen overlamping cause serious issues in older homes. It’s a code violation that happens when someone uses a light bulb with higher wattage than the fixture can handle safely.

This mistake poses a high fire risk due to overheating. We always advise sticking to the wattage limits on fixtures. For older ones, it’s best to use 60-watt bulbs or smaller.

Preventing overlamping is crucial for home safety. We recommend installing a circuit breaker and upgrading your wiring system. It’s also wise to avoid relying too much on extension cords, as they can contribute to overlamping problems.

By taking these steps, we can significantly reduce the risk of electrical fires in our homes.

Uncovered Junction Boxes

Uncovered junction boxes pose a serious risk in older homes. These exposed connections can lead to wire damage or electric shocks, violating electrical codes. Our team at Ottawa Electric often encounters this issue during inspections.

Uncovered Junction Boxes

We've seen firsthand how exposed wires in these boxes can deteriorate over time, increasing the danger of electrical faults. Fortunately, fixing this problem is straightforward and cost-effective. A new cover for a junction box costs mere pennies and takes minutes to install. By ensuring all junction boxes are properly covered, homeowners can prevent potential electrical issues and improve safety.

As master electricians, we always stress the importance of this simple yet crucial step in maintaining a home’s electrical system.

Aluminium Wiring

We often encounter aluminium wiring in homes built during the 1960s and 1970s. This type of electrical conductor was popular then, but it can pose risks. Aluminium wires can corrode when they touch copper, causing loose connections.

This increases the chance of power surges and fire hazards.

Luckily, we’ve got a simple fix for this common old house electrical problem. We install dielectric wire nuts at each copper-aluminium junction. These special connectors cost less than £1 each and prevent corrosion.

While not a code violation, upgrading these connections greatly improves safety in older homes with aluminium wiring.

Backstabbed Wires

Backstabbed wires pose a significant risk in older homes. These wires, pushed into the back of switches and outlets, are prone to loosening over time. At Ottawa Electric, we’ve seen countless cases where this wiring method has led to electrical fires.

Our team always recommends inspecting these connections during routine maintenance.

We strongly advise homeowners to secure wires to screw terminals instead. This method provides a more stable connection and reduces the risk of electrical issues. While backstabbed wiring is still allowed in new builds, our experience shows it’s not the safest option.

We’ve made it our mission to educate clients about these hidden dangers and offer safer alternatives.
