Is Your Paris Home Electrical System Safely Grounded?




Paris Electrical SystemWhat is electrical grounding, anyway?

Grounding adds a safety factor for your family and your electronics. Here’s how it works. Electricity travels the path of least resistance. If an appliance like a toaster breaks, electricity can flow on the metal outside of the toaster. Touching it could result in a serious shock, causing injury or even death. But if the Paris electrical system is grounded and the toaster is plugged in with three prongs, the electricity won’t flow to the outside of the toaster. Instead it will flow through the third prong back into the wires and harmlessly into the earth. Thus, the term “grounding.”

An electrical system can be grounded with various types of devices. A “ground wire” is simply a wire attached to your electrical system that’s been pushed securely into the ground. Metal pipes (electricians call them “conduit”) that hold and protect your electrical wires can also act as a grounding device. Sometimes, grounding is provided by running a wire from your electrical system and attaching it to metal plumbing pipes that run into the ground.

Grounding protects not only people but also sensitive electronics. Without grounding, electrical charges build up in wiring and create slight but continuous damage to delicate electronics. This damage can shorten the lives of computers, phones, and any electrical appliance that has “smart” (computer) components, possibly your fridge or dryer.

How can I tell if my electrical system is grounded?

Homes built before 1950 were sometimes grounded. Paris homes built after 1950 were usually grounded. Even if your system was originally grounded, wiring mistakes may have rendered the grounding ineffective. Even with outlets that accept three prongs, it doesn’t necessarily mean that your electrical wiring is grounded. The only way to know for sure is to have a qualified electrician check out your electrical system with a special tester.

My electrical outlets have three prongs — aren’t they grounded?

If your home has electrical outlets which accept three prongs, it MAY have a grounded system. The third prong allows an appliance to be grounded IF it’s plugged into an electrical system that has a grounding device. Sometimes three-pronged outlets have been installed in electrical systems that has no grounding device. This can make it look like the system is grounded when it’s not. Do-it-yourselfers or handymen may install three-pronged outlets in an ungrounded system not realizing the hazard and not knowing that it violates the National Electrical Code.
