In older homes, you can uncover beautiful features we no longer see today, such as fully wooden doors and intricate molding. However, you also encounter some risks, since despite popular belief, not everything was higher quality back in the day. One of those areas of concern you should be sure to check is your home's electrical wiring. In this article, you will learn how to identify what kind of wiring your home has and the risks that come with it, before deciding whether to repair or replace.
Step 1: Identify the Type of Wiring
- Knob-and-Tube — Knob-and-Tube (K&T) is one of the oldest forms of wiring in the U.S., and it is pretty easy to identify since it looks like the namesake knobs and tubes. This is the wiring most likely to be found if your home is from the late 1800s-1930s.
- Cloth Wiring — If you have K&T, you also may have cloth wiring. Cloth wiring was commonplace in homes built before the 1960s, and it is unfortunately difficult to identify. Since this type of wiring is prone to becoming brittle, we don't recommend touching it yourself to identify, and instead call a professional Atlanta electrician.
- Aluminum Wiring — One of the more short-lived wiring trends, aluminum is likely in homes built between the 1960s-70s. One of the easiest ways to check for this type of wiring is by looking for etching that says aluminum, alum, or AL on the wire's insulation. When looking for these markings, remember not to touch any live wires.
Step 2: Assess the risks
Knob-and-Tube — K&T is one of the most problematic types of wiring for homeowners, since you often can't get insured if you have it, which is a big red flag when determining the safety of your home. One of the biggest problems with K&T is that there is no ground wire. Simply put, ground wire runs through the ground to let any excess electricity out safely, preventing fires. This fire hazard is the main reason people may look to replace K&T.
Cloth Wiring — Since cloth wiring is typically a part of K&T, you still have all of the problems that come along with that system. One of the distinct problems with cloth wiring though is how brittle it becomes, leading to exposed wire. That isn't where the exposed wire dilemmas end though, since cloth is easily broken through by household pests, from termites to rats, much easier than modern rubberized coating. The more wiring that is exposed, the more flammable the wiring becomes, posing another fire hazard in your home.
Aluminum Wiring — Based on the trend of this article, you can likely guess what the biggest concern with aluminum wiring is. If you guessed fire hazards, you'd be right. Aluminum oxides faster than copper, which prevents it from conducting electricity properly. It also creates what are called "loose connections" by expanding and contracting at a higher rate, which can lead to a fire breaking out. Not only that, homes with aluminum wiring are 55 times more likely to have fire hazards.
Step 3: Call an expert
After reading about the hazards of old wiring, you are likely wanting to solve the problem by repairing or replacing the wiring in your home. There are DIY solutions to help ease the concerns of older wiring, but they are all hazardous to install, and many don't even solve the problem in full. When dealing with wiring, the best thing to do is to call a professional specialized in electrical services and home wiring.
