If you’re not sure whether or not your house uses k&t wiring, it’s worth taking some time to do a brief inspection of the property to find out. The easiest method will involve checking key areas, such as exposed joints in the basement or attic, for any white ceramic knobs nailed to the joists with electrical wiring twisting through them. Barring any unpredictable circumstances, the presence of these telltale signs will almost certainly mean that your house was wired using the k&t method.
It’s worth pointing out, too, that you may still have k&t wiring in your home even if you don’t find any of these indications. In these cases, you’ll want to plan a complete diagnostic to be absolutely certain of what wiring your home uses. In the end, you’ll feel safe, secure and more knowledgeable of your home overall—and both you and the property will be better off for it.
