Which of the following is an effect of outdated wiring?

Outdated wiring can create significant safety hazards due to factors such as deterioration and inability to handle modern electrical loads. Old wiring may not be insulated properly or could be comprised of materials that are no longer considered safe by current standards. These issues can lead to overheating or short circuits, significantly increasing the likelihood of electrical fires.

Furthermore, as electrical demands in homes and businesses grow, outdated wiring may not be able to manage the current effectively, leading to circuit overloads and further exacerbating the risks. This is why the connection between outdated wiring and an increased risk of electrical fires is an important consideration in electrical safety practices.
