Knob and Tube Wiring

We think of the wiring in our home as the arteries of power that feeds everything electrical in the household. Do you wonder if parts of it can become damaged or deteriorate over time? Can it present a serious fire or shock hazard? Any of these questions can be answered by an experienced professional. Only an experienced professional can answer to the condition of your old wiring and if your power panel can handle the electrical load of your home.

There are a few things to keep in mind to help with the beginning assessment of old wiring.

1. Identify old wiring: Knob and Tube is the oldest type of wiring and we have seen this in some of the older homes we have serviced in Erie, PA. These systems date back to pre1940. Knob and Tube may lack grounding that is needed for safety. You can keep Knob and Tube wiring according to the National Electrical Code (NEC) but you must follow local codes when adding to or changing.

2. Knob and Tube becomes dangerous when the wiring insulation wears away. There can be a problem when alterations weren’t performed properly and to code. And, there can also be issues with covering it with building insulation.  All these can be potential fire hazards.

If you have concerns about your wiring, contact a professional electrician.  If you have a fire, contact the professional fire restoration specialists, SERVPRO of West Erie County.
