Renovations provide an excellent opportunity to replace outdated or unsafe wiring, add more outlets, improve lighting, and enhance overall electrical safety and convenience.

Does your home insurance require certain electrical upgrades?

• Fuse box replacement: Many insurance companies require homes to have circuit breakers instead of fuse boxes. This is because fuse boxes, which are common in older homes, are considered less safe than modern electrical panels with circuit breakers. Fuse boxes use fuses that must be replaced when they blow, while circuit breakers simply need to be reset. This makes circuit breakers more convenient, but more importantly, it also makes them safer, as there’s less risk of incorrectly replacing a fuse, which could lead to electrical fires.
• Aluminum wiring replacement: Aluminum was widely used as a cheaper alternative to copper in homes built from the mid-1960s to the late 1970s. However, aluminum can oxidize and corrode when in contact with certain metals, potentially leading to loose connections, arcing, overheating, and fire hazards. For these reasons, many insurers consider aluminum wiring a risk and may ask for it to be replaced with copper wiring.
• Knob and tube wiring replacement: Knob and tube wiring was common in homes built before 1950. It’s considered unsafe by many insurance companies due to its lack of a grounding conductor, its tendency to be covered with building insulation (which can cause overheating), and its susceptibility to wear and tear. Insurers may require its replacement as a condition of providing coverage.
• Upgrading to a grounded system: Modern electrical systems include a grounding wire that provides a safe path for electricity to follow in case of any issues like a short circuit. This significantly reduces the risk of electric shock or electrical fire. Some insurance companies may require that your home’s electrical system include this grounding wire.
• Increasing service amperage: Older homes often have 60-amp electrical service. However, modern homes with modern appliances typically require at least 100-amp service. This is because modern appliances generally use more electricity, and a 60-amp service might not be able to handle this increased load, leading to potential safety issues. Consequently, insurers may require an upgrade to at least 100-amp service.

Are there specific electrical codes that guide wiring upgrades?

There are specific electrical codes that guide wiring upgrades. These codes are detailed rules and standards set by organizations like the National Electrical Code (NEC) in the United States, which is part of the National Fire Protection Association (NFPA). The NEC sets the standard for safe electrical design, installation, and inspection to protect people and property from electrical hazards.

It covers several aspects of home wiring, including the types of wires and cables to use, where and how they can be run, grounding systems, maximum outlet spacing, and more. It’s updated every three years to incorporate new technologies and methods.

When performing an electrical upgrade, a licensed electrician is required to follow these codes, and the completed work often must be inspected by a local building department or electrical authority to ensure it complies with these local and national codes. Ignoring these codes during an upgrade can result in unsafe conditions, legal issues, and problems when trying to sell your home.

How frequent should routine inspections of electrical wiring be?

The frequency of routine inspections for electrical wiring can depend on a few factors, such as the age of your home, the type of wiring, and your power usage.
