Fishing a wire for a ceiling fan

Here is how we fished a new switch leg in to an old 1930's knob and tube switch box. This home was in the Overbrook section of Philadelphia (19131). Getting rid of 80 year old wiring is a must for a safe home.

First we cut a hole at the top of the plaster and lath wall. The we dropped a piece of jack chain. Jack chain work much better then a fish. This wall is plaster on the inside and stone on the exterior. Either of which would make it difficult to use a tape fish. The weight of the jack chain make it fall right down.

We use a fish to find the jack chain under the switch box that was directly below the hole. With the jack chain at the wall box we pulled the new 14-3 ceiling fan wire into the old box. The new wire can then be fished from the space under the box into one of the wire holes in the back of the box.

  3. Most importantly, when you are endeavoring to locate the best fans for your home, you will need to consider the size. Roof fans can be found in a wide range of sizes; nonetheless, the extent of the room you are purchasing for will impact this choice.
