Updating knob tube wiring

The average cost to install a new circuit breaker panel is

The average cost to install a new circuit breaker panel is $1,100 for a 100-amp service.The higher the amperage, the more you can expect to pay due to larger gauge wiring required and higher amperage panels are also usually larger and have more circuits.The extent of demolition and the difficulty of getting the old wiring out will determine how much removal will cost.Depending on how much of the old wall covering you want to preserve, some wiring might be impossible to remove, especially if there is blown-in foam insulation covering the wires.Knob and tube wiring was the standard method of wiring for a new home from the late 1800s right up until the 1950s.Although there is nothing inherently “unsafe” about knob and tube wiring, its age and two-wire construction (no ground) makes it a risk with today’s modern electricity usage.The national average to remove and rewire knob and tube wiring is $3,500 to $8,000.

Often, homes that have knob and tube wiring also have a legacy fuse box that will need to be upgraded to a modern circuit breaker panel.

Most electricians do not charge by the foot for this type of project, but the average works out to about to per linear foot and to for heavy-duty electrical wiring to support entertainment rooms and high-voltage appliances.

Part of replacing knob and tube wiring will be upgrading the receptacles and junction boxes in the walls.

It generally costs more for specialty circuits like ground-fault circuit interrupter (GFCI) or Arc Fault Circuit Interrupter (AFCI), which have a higher cost of around – per breaker.

A GFCI outlet must get installed wherever there is water, like bathrooms and kitchens, and the AFCI where there are large voltage requirements on the wires, like entertainment rooms and studies with lots of computer equipment.
