Circuit Breakers Vs Fuse Boxes: What Inspectors Look For

Circuit Breaker Panel Inspection: What to Expect

When you schedule an electrical inspection, the expert will look for the overall integrity of the system, checking that it distributes electricity safely. Here’s what inspectors look for:

“Double Tapping”

A major red flag that inspectors often look for is “double tapping,” which refers to wires connected to a single circuit breaker. This goes against electrical codes and safety regulations, unless the breaker is specifically designed to handle two wires. While “double tapping” may not be a cause for concern initially, ignoring it can render the device ineffective when you need it the most.

Problematic Brands

Although Federal Pacific (FPE) Stab-Lok, Zinsco, and Sylvania panels were never formally banned or officially recalled, they are considered major fire hazards. It is highly recommended by trained electricians and inspectors to replace these panels before they fail when you need them the most. The last thing you want is an unprotected electrical system, especially during adverse weather.

Improper Grounding and Bonding

Electricians and inspectors ensure that the panel is correctly connected to the ground, allowing for safe dissipation of electrical faults. If left unattended, improper grounding and bonding can cause significant hazards, such as shocks, electrical fires, and destruction of sensitive electronics. It is essential to regularly consult a professional to inspect and repair your panels before things get out of hand.

What Is a Fuse Box?

A fuse box is more like an older version of the circuit breaker. Fuse boxes are found in buildings built before the 1960s, and often cannot handle the electrical demands of modern appliances. Unlike circuit breaker panels that use a switch, a fuse box uses a fuse. This is a device with a wire or a metal filament inside. When excess current flows through, the wire melts instantly, breaking the circuit and stopping electricity.

Fuse Box Inspections: What to Expect

Now that you know what a fuse box is, let’s explore common issues inspectors flag to ensure early intervention.

Tamper-Resistant Fuses

Electricians and inspectors look for tinfoil or pennies behind fuses, a dangerous DIY trick used to keep power running when a circuit is overloaded. While this method can bypass the safety mechanism and restore power, it can lead to serious electrical hazards.

Overheating or Wear

Another red flag that inspectors look for is cloudy or blackened fuses or glass. This is usually accompanied by charred plastic or melted fuse holders inside the box, prompting immediate attention. Overheating or wear may not raise concerns initially, but they worsen and cause devastating damage over time.
