Common Electrical Testers for the Home

Most of us consider certain things to be essential in our tool box or junk drawer. I would guess 99% of us know where a hammer, flathead screwdriver, phi­­llips screwdriver and a pair of pliers can be found in our home. Here are a couple of the most common electrical testers you might want to add to your arsenal, if you have not already.

Inductance Tester (Non-contact voltage tester) – This is the safest and easiest tool for testing voltages. Why? Because you do not even have to touch the wires! Just by touching the outside of wiring or into an outlet, this can sense the presence of voltage.

As with most any tool, the price will determine if it will provide only a yes or no answer, or instead give you a basic measurement of the voltage it found. This is an easy to use tool that all homeowners should have at their disposal. It is battery operated, so always test that it is in working condition before using on your next project.

Neon Circuit Test – This is the most basic testers. It will only tell you whether or not there is voltage in a circuit. Use one probe to touch a hot wire and the other to touch ground. The neon bulb will light up if current is present. Sounds a little like a children’s school science project, doesn’t it?

This tool does not do any measuring, but its added bonus is that it does not require a battery. That makes it extra convenient to have stored away and forgotten until you need it.

Plug-in Circuit Analyzer – This tool does exactly what you might expect. Plug it into the grounded 3-slot outlet you want to test and it analyzes the circuit without any external power (that means no batteries to check).

You’ll be able to tell if a circuit is correctly wired, if it is an open circuit, and also be able to confirm the presence of a ground connection. This is a very affordable tool that you may want to add.

Before using any electrical tool always completely read the instructions. Always investigate if power should be turned off. Safety should always be your first priority!

Is Aluminum Wiring in Your Home Safe?

 If you have aluminum wiring in your home, you are not alone. It was commonly used in our area primarily during the years of 1965 and 1973. Copper prices were rising and builders were trying to find ways to lower costs. What they didn’t realize at the time, was that aluminum wiring was going to create safety issues.

The U.S. Consumer Product Safety Commission (CPSC) states that houses built with aluminum wiring are 55 times more likely to have “fire hazard” conditions than those homes that used copper wiring. If your home was built during that time, then you should consider confirming what type of wiring you have in your home.

Aluminum wiring can conduct electricity safely. That’s not where the main safety issue lies. The extra heat generated by aluminum wiring causes problems at the connections. That’s why completely rewiring your home does not have to be the only answer. The more practical and affordable solution is to add copper wiring to the connections instead.

Professional electricians are able to install connectors that have been created as an alternative solution to the aluminum wiring problem. Your electrician can discuss with you what type of connectors are available, and what may be the best fit for your home.
