Now that my wife has married an electrician, she insists that I take every possible measure to ensure that the electrical system of our Los Angeles home is safe. One important step was to ensure that it’s properly grounded.

What 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 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 Mother 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 earth.

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. Homes built after 1950 were usually grounded. Even if your system was originally grounded, wiring mistakes may have rendered the grounding ineffective. The only way to know for sure is to have a qualified electrician check out your electrical system with a special tester. My electrical company, The Electric Connection, offers this check as a complementary service. It’s part of our Free Home Safety Inspection when we do an electrical job for an L.A. resident or business. If you’re outside Los Angeles County, you may find an electrical contractor who offers testing as a free service or as a service call.

My electrical outlets have three prongs — are 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 aren’t grounded. 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 or that such a set-up violates the National Electrical Code.

When winter weather hits, a standby generator can be crucial for keeping your home’s essential functions, including heat (either from your main HVAC system or from a space heater) running. But ice storms and freezing temperatures can prevent the generator from working properly when you need it most. Fortunately, there are a number of add-ons you can install on your generator to keep it running smoothly, even when the thermostat plunges!

You probably already know that cold weather can kill your car’s battery. Well it’s the same for your generator! Thermostatically controlled battery warmers go underneath the battery, turning on when the temperature drops below 40 F. The best part about battery warmers is you don’t have to monitor them—they’re just set and forget.

Warm oil acts as a slippery lubricant, keeping all the parts of your generator moving the way they’re supposed to. Cold oil, on the other hand, turns into a sludge-like substance that can actually prevent movement! A cold weather kit will include a crank case heater that prevents the oil from getting so cold that it becomes unusable.

Manufacturers recommend replacing the standard 10W-30 oil with 5W-30 Synthetic Oil if you do decide to add a heater.

Generac cold weather kits are recommended for CorePower units installed in areas where temperatures below 32 F are common, which includes our area. For generator services in Maryland, Virginia, or Washington, DC, call Kolb Electric today!
