For homes built before the 1950s, wiring knob replacement in Media, PA, can be an important electrical safety improvement. State of the art at the time, this system of stringing rubber-insulated wiring along a series of ceramic knobs and tubes is long outdated. Aging materials and updated wiring standards make tube replacement with plastic-jacketed wiring a wise choice.

In addition, updating the two wires used earlier to today’s three-wire system, including a ground wire, helps avoid shocks and electrical fires. While this system can look elegant running through your attic and walls, having your power run through it presents risks and limitations.
