In the late sixties, and early seventies aluminum wiring began to be used because most available copper was going to the Vietnam war effort. However, aluminum wiring is not ideal for small home electrical systems.  The electrical devices at that time were not designed to handle the high temperature coefficients of aluminum wiring. Aluminum wires can also expand in diameter and length as they get hot, they can actually back out the screw terminals, causing a loose connection. This, in turn, can cause heat, which can ultimately lead to a fire.

After problems with aluminum wire termination became known—including one notable house fire—the UL (Underwriters Laboratories) and other agencies adopted new safety regulations and put more restrictive standards in place. However, many homes from the 60s and 70s still do not have safe aluminum wiring terminations. But there are a number of ways to solve this problem without having to rewire a home.

Consumer Safety Council Recommendations

According to the Consumer Safety Council, there are only two approved methods that splice aluminum wire to copper wire:

These standards have caused acceptance problems with home inspectors and insurance companies, which has led to homeowners paying 2 to 4  times as much as they should to have their aluminum wiring terminated.

Most people don’t think about all the switches and connections that happen when you flick a switch or hit the power button on an appliance – at least, not until the item doesn’t work. The electricity in your home travels over an amazing, complex system, and there can be a lot of reasons why you may need Circuit breakers are not one-size-fits all, and there are 3 important items to review before installing any circuit breaker into an electrical box: the load capacity, whether or not the breaker is compatible with the others in your electrical panel and the limitations of a particular circuit breaker, which will tell you how and what a circuit breaker will protect. Faulty circuit breakers need to be replaced as they cannot be repaired.

Improperly Sized Electrical Panel

The electrical panel in your home is designed to deliver and manage a specific amount of electricity. If the panel is too small, you may trip circuit breakers consistently, causing appliances to shut down. Having too much power flow through your electrical box has the potential to give electrical shocks and cause fires. Adding a room to your home requires more than just adding another circuit breaker; the panel has to be able to deliver and manage the needed electricity for the new space. This is why it’s important to always hire a professional for all electrical work.
