Homes with fuse boxes, while not inherently unsafe, pose several dangers for homeowners, particularly those built before the 1980s. The risks are typically caused by homeowner misuse or the system's inability to handle modern electrical demands, which can lead to fire, appliance damage, and higher insurance costs.
Fire and electric shock hazards
- Improper modifications: The most significant danger is when a homeowner puts a fuse with a higher amperage rating into a circuit than it was designed for. This allows too much electricity to flow, which can cause the wiring to overheat, melt, and start a fire behind the walls. Some desperate homeowners have even put pennies behind blown fuses, which completely bypasses the safety mechanism.
- Breaker failure: While circuit breakers became more common after 1970, many homes from this period still have outdated and potentially faulty panels. Notably, Federal Pacific Electric (FPE) "Stab-Lok" panels, widely installed in the 1970s and 1980s, are known for a high rate of failure, with their breakers failing to trip during an overload or short circuit. This can lead to overheating and fire.
- Corroded and frayed wires: Because these systems are old, the components are prone to degradation. Over time, connections can corrode and wires can become frayed, which increases the risk of arcing and electric shock.
- Lack of modern safety features: Older fuse boxes and breaker panels lack modern safety devices like Ground Fault Circuit Interrupters (GFCIs) and Arc Fault Circuit Interrupters (AFCIs). These devices are essential for preventing shock and fires.
System overload
- Not designed for modern electricity use: Homes built decades ago were not designed for today's heavy electrical loads, which include multiple computers, large televisions, and numerous modern appliances. Many older panels have a capacity of only 60 to 100 amps, while modern homes often require 200 amps.
- Frequent overloads: When an outdated system is stressed with a modern electrical load, fuses will blow frequently. If circuits are frequently blowing fuses, it is a key sign that the panel is overtaxed and requires an upgrade.
Other risks for homeowners
- Decreased home value and insurance difficulties: Many insurance companies will charge higher premiums or may refuse to cover a home with an outdated fuse box due to the increased risk of fire. For sellers, this can also make the home less appealing and reduce its value.
- DIY dangers: Replacing or repairing an electrical panel is not a DIY job. A homeowner attempting to do so is at risk of serious injury or death from electrocution.
What to do
If you have an old fuse box or an outdated breaker panel in your home, it is recommended that you:
- Schedule an inspection: Have a licensed electrician inspect your electrical panel to assess its condition and capacity.
- Consider an upgrade: If an inspector recommends it, replace the fuse box or old panel with a modern breaker panel to ensure the safety and efficiency of your electrical system.
- Practice safe usage: Avoid plugging multiple high-demand devices into a single circuit to reduce the risk of overloads.
- Replace fuses properly: If you have fuses, always replace a blown fuse with one of the identical type and amperage. Never use an oversized fuse or a makeshift item like a penny.
