For many years, people have used the old-fashioned technique of knob and tube wiring to connect their lights to outlets. These types of circuits are supported by ceramic tubes that are inserted into holes in the wood framing. Adding another load to these circuits can increase their temperature and risk a fire. These methods are now illegal in many jurisdictions, and many insurance providers will not cover a home that is at this level of risk for electrical fires.
