Frequently Asked Questions (FAQs)
Which types of wiring systems are now considered unsafe and old?
Systems like knob and tube wiring and aluminum wiring are considered outdated and obsolete. As time passes and flaws are identified in facets of a type of wiring system, new materials are engineered to increase safety and efficiency. In the case of knob and tube wiring, its exposed nature to the elements and the fact that it is insulated with rubberized cloth makes it a major safety hazard (putting homeowners at risk for shock and house fires). Aluminum wiring, although malleable and easy to work with, is soft, making it likely to come loose from terminals and fray. This causes it to be high maintenance, requiring inspections every 3-5 years.
Will new wiring systems need to be eventually replaced?
A good rule of thumb is to have wiring upgraded at least once every generation (40-50 years). By then, significant technological advancements will have taken place in order to accommodate increased demands of electricity. If your home has not had a wiring upgrade since 1970s to 1980s or earlier, it may be time for an electrical inspection.
Can I do renovations without upgrading my wiring?
This can depend on how advanced your electrical system already is. If you have a copper wiring system and sufficient electrical capacity, you may be all set for renovations. If your wiring is outdated, however, it’s highly recommended to have this upgraded first. An incompatible wiring system can be dangerous, as it’s often one will less tolerance for higher electrical loads. Placing consistent stress on your wiring system puts it at risk for malfunctioning or short-circuiting.
