Generally, knob and tube wiring will date prior to 1940, when electrical systems had notably less demands on them than what you usually see today. Homeowners discover that these systems lack the capacity they require. Over time, factors such as rodents and building renovations may result in damage to the wiring, which is also important to consider. A lot of insurance companies require this to be upgraded due to the increased danger before they’ll provide coverage, which makes it important to consider an upgrade.
