What is a significant concern regarding older home electrical systems?

A significant concern regarding older home electrical systems is the presence of outdated wiring that may pose fire hazards. Electrical systems that were installed many decades ago often do not meet current safety standards and codes. Wires may be made of materials that are more prone to wear, overheating, and insulation degradation, which significantly increases the risk of electrical fires.

Additionally, older wiring may not have the necessary capacity to handle the load of modern appliances and technologies that require more power. This mismatch can lead to overheating and potential circuit failures. Regular inspections and updates of the electrical system are crucial for safety in homes with older systems to minimize these risks.
