Frequently Asked Questions (FAQs)
Why is knob and tube wiring no longer considered safe?
Wiring connections today are required for safety reasons to be enclosed in electrical junction boxes, but knob and tube wiring was often left suspended in the air. For homes that no longer actively use knob and tube wiring systems, it’s not uncommon for remnants to be hidden behind the walls of homes. Since knob and tube wiring is insulated with a rubberized cloth and lacks grounding, it’s considered today to be a safety hazard. The fact that it has less distribution circuits makes it prone to overheating, presenting a fire hazard.
What are the benefits of hiring a licensed electrician for replacing old, unsafe wiring?
Since wiring can be a rather large and complicated job, hiring a professional can save you unnecessary expense, reducing the likelihood of mistakes needing to be fixed, as well as saving you the trouble in project management. Professionals will have the specialized knowledge required to ensure that the process runs as smoothly as possible. A licensed electrician, for example, will know to colour code and label wiring accordingly.
What is the best kind of replacement wiring for my home?
Replacements in wiring are often done with copper wiring being installed since it is currently the most stable, reliable, and cost-efficient. Since copper allows for smaller conductors to be used to transmit power loads, it can reduce overall wiring expenses. Compared to aluminum, copper also has higher tensile strength, allowing it to handle higher loads of electrical with minimal wear and tear.
