Frequently Asked Questions (FAQs)
What wiring systems are considered the best for the modern home?
Copper wiring is now considered the most stable and reliable form of wiring. Highly preferred by electrical experts and modern homeowners, most new homes are wired using copper material. It was previously considered expensive compared to aluminum, but over time proved to be cost-effective in reducing wiring, maintenance, and inspection expenses. As it allowed for smaller conductors to transmit larger electrical loads, with its higher tensile strength reducing the likelihood of wear and tear, copper soon became the favored medium for wiring.
Why is old wiring unsafe the more it ages out?
Besides being incompatible with technological advacements (which can place strain on outdated electrical systems), the older a wiring system is and the longer it goes unchecked, the more likely it is to compound in damage with aging. Modern wiring is insulated with plastic, but older systems like knob and tube wiring are wrapped in a rubberized cloth, which can crack and flake off over time. Since aluminum is such soft material, it can end up being very high-maintenance.
Is knob and tube wiring or aluminum wiring okay to keep in the home?
Homeowners can technically choose to keep knob and tube or aluminum wiring, but the drawbacks are much greater than upgrading. Along with the risk, they may, for example, find themselves encountering greater difficulties and inconveniences in insuring, securing financing, or selling their home. Since older wiring is considered unsafe and a major safety hazard, lenders and insurance companies may be hesitant to get involved in these kinds of properties until electrical upgrades have taken place. Additionally, maintaining older wiring systems can also be more costly, with maintenance and inspection recommended every 3-5 years.
