Talking with your Electrician about older wiring in your home and having a game plan

by Lauterborn Electric on December 7th, 2011

We always start our conversation with a home owner who has older wiring in their home by saying,” if this was our home we would replace all the wiring,” but it is easy for us to say. We are Electricians.

The two images below show knob and tube wiring.

  1. The first thing we do when we access the electric in your home is evaluate the main electrical service condition and size. You cannot add circuitry in a home if the size of the service cannot handle it.
  2. We also make sure the system is properly grounded, including ground rod and cold water connection to the main service.
  3. By looking at the main service and the wiring coming out of the panel it gives us a good idea of the wiring of the home.
  4. If your home was built around 1950 or before, knob and tube wiring is what we normally find. Although the wiring in homes built in the 1970-80s’ era has grounding, many of these homes lack today’s codes.
  5. Rewiring of a home can be an expensive undertaking, but by taking some steps and understanding the wiring in your home you can lessen the risk of electrical failure.

Here are some steps we recommend to alleviate the load on older wiring.

  • -Run a dedicated 20 AMP circuit into your bathroom and install a GFCI.

Hair dryers and curling irons have a large current draw that puts stress on older wiring.

  •  -Run dedicated lines for your major appliances including:

Refrigerator-dishwasher- disposal- washer-dryer and even air conditioning wall units.

  • -Run 2 dedicated 20 AMP circuits for your kitchen counter     area and install GFCIs.

Microwave-Toaster-blender-coffee pot- electric can openers are current eaters.

Running some of the items listed above in a home with older wiring can lead to overloading or over heating of the wiring. The perfect solution to older wiring woes is the complete rewiring of a home. Taking the steps listed above is the beginning of making your home electrically safer.
