Copper-plated wiring, copper-clad aluminum, and bare copper wiring are expected to last a lifetime, whereas 
electrical accessories and lighting controls, such as dimmer switches, may need to be replaced after 10 
years. GFCIs could last 30 years, but much less if tripped regularly. 

Remember that faulty, damaged or overloaded electrical circuits or equipment are the leading cause of 
house fires, so they should be inspected regularly and repaired or updated as needed.
