GFCIs - What the heck are they?

3/31/2023

First, let’s talk about what GFCI stands for. Ground Fault Circuit Interrupter. They can be found in our kitchens, our bathrooms, on the exterior of our homes, sometimes in our bedrooms, and even in our basements. Go ahead and take a look around your home. I guarantee you’ll find several.
 
So, what are GFCI outlets, why are they needed, and how do they work?
 
GFCIs are designed to protect electrical wiring by causing the circuit to close or break whenever an imbalance occurs between outgoing and incoming circuitry. GFCIs are particularly important in areas of your home that are near water…bathrooms, kitchens, etc.
 
A GFCI looks like any standard outlet. However, it includes a “test” button and a “reset” button and unlike a standard outlet it continually measures the flow of electricity through it. I think most of us know about the effects of electrocution on the body that once a shock occurs the current can be so strong that we simple humans are unable to pry our hands away. So, the GFCI is here to help. They are incredibly sensitive to any change in electrical current and if it senses an issue the GFCI will immediately (like within 1/10th of a second) shut the power off without us having to do anything. For example, if you accidentally drop your plugged-in hair dryer in a sink full of water the GFCI would sense the power variance (as small as 4 to 5 milliamps) and immediately cut the power.
 
Being the amazing contractor that I am I bet you’re asking yourself what the difference is between a breaker inside your electrical panel and a GFCI.  A breaker and a GFCI are both helpful in preventing terrible things from happening, but they are vastly different. A breaker is generally associated with the protection of your home from electrical fires. Really important stuff obviously but little to do with the prevention of electrical shocks produced by outlets. That’s where GFCIs come in by directly detecting interruptions in electrical current and cutting power right then and there possibly saving your life.
 
How can you tell when a GFCI is going bad or is bad?
 
Just like most everything else in our world nothing lasts forever (my knees are a great example). GFCIs do wear out with age so it’s important to know how to test them. It’s pretty easy. All you have to do is grab some sort of electrical appliance and plug it into the GFCI and make sure the appliance is on and receiving power. Then while the appliance is on push the “test” button on the GFCI and the appliance should lose power and turn off. If that happens, you’re halfway there. Finally, push the “reset” button and your appliance of choice should regain power. That’s it. If the appliance lost power after pushing the “test” button and then regained power after pushing the “reset” button you’re good.

If your appliance didn’t lose power after pushing the “test” button or regain power after pushing the “reset” button then you need to immediately, without delay, either fix the issue yourself or call an expert. It could be that the GFCI is bad (just like my knees things we use all the time don’t last forever) or it could be that there’s a larger issue with how the GFCI is wired. Seriously, if you think you have an issue or one of your GFCIs fails the test procedure get it taken care of.
 
Finally, there are certain instances when a GFCI can trip repeatedly when there isn’t really an issue. This type of nuisance tripping tends to be caused by slight variations in the electrical current running through them. Here are some ways to avoid this issue…
 
  • Maintain all your power tools in good condition…no frayed wires, no sticky buttons, etc.
  • Use GFCIs only for circuits that are 100’ long or less
  • Do not connect stationary motors to a GFCI outlet
 
This is so important that I’ll say it one last time…if you suspect (even just a tiny bit) that you have an issue with one of your GFCIs replace it. They’re pretty inexpensive for something that can literally save your life.

10 Home Maintenance Tips for Spring

3/26/2023

Spring seems to finally be here and with it brings about much-needed spring home maintenance including leaf-filled gutters, possible shingle issues, and HVAC maintenance. Following are 10 tips for spring:
 
  1. Take a good look at the exterior of your chimney for signs of deterioration. Make sure the chimney cap is still there and in good shape and check out the siding around the chimney and make sure it’s all there and in good shape. If you have brick or stone grab some binoculars and take a close look at the grout joints and make sure that the joints are intact and in good shape.

  2. Since you have binoculars out walk around your house and check out your shingles. Make sure they aren’t cracked, buckled, loose, or even missing (we’ve had some crazy high wind in Central Ohio lately).

  3. Since you’re already walking around your house look at all the trim (gables, soffits, around windows) and the windows themselves. Look for missing caulk (that could let in water and cause rot), soft spots on the trim and windows (indicates rot), and missing paint.

  4. While you’re walking around your house looking at the trim also keep an eye open for low areas in the yard and especially around your foundation. All low areas (especially around the foundation) should be filled with compacted topsoil to help prevent basement water issues and eliminate low areas (pooling water) where insects can breed.

  5. Check for loose or leaky gutters. Bad drainage can lead to water in your basement or crawl space. Make sure all downspouts drain away from the foundation and are clear of debris.

  6. Remove firewood stored near your house. It should be stored at least 18” off the ground and at least 2 feet from any structure.

  7. Have a qualified heating and cooling contractor clean and service the outside unit. Clean coils operate more efficiently, and an annual service will keep the system working at peak performance levels.

  8. Change the batteries in your smoke alarms and carbon monoxide alarms and test each one of them to make sure they are all functioning correctly (if one works it doesn’t necessarily mean all of them are working). According to the National Fire Protection Association an average of 1,450 fire deaths occur every year in homes with missing or non-functioning smoke alarms.

  9. Clean out your dryer vent. There are several companies that will do this for you or you can do it yourself with an electric (NEVER use gas-powered equipment inside your home) leaf blower. Just unhook your dryer from the duct, stick the business end of the ELECTRIC leaf blower into the duct, wrap a wet towel around the opening to keep lint from blocking back into the room, and turn on the blower. Again, DO NOT use a gas-powered leaf blower inside your home!
    ​

  10. Finally, before outside temperatures are regularly warm enough that we can enjoy having the windows open check your screens. In fact, I’m typing this in my home office and just looked out a window and noticed I have a torn screen. Most local hardware stores will replace screens (assuming the frame is in good condition) for a reasonable amount.
