Repair Damaged Electrical Wiring
Flex Conduit in block wall with damaged 14 2 wires
Drilling through a cinder block wall damaged a Flex Conduit and one or both 14 2 wires.
The wires go to an outside GFCI outlet, and an inside bedroom outlet.
I cannot pull the wires out to examine them, and the circuit breaker tripped once the conduit was hit.
Is there a way to extract the wires and or the flex conduit?

Repairing Damaged Electrical Wiring Inside a Wall
- Bob, Sorry to hear about this problem, lets see how it may be fixed:
Disconnect and Expose the Wiring
From what you have described, the other end of the flex conduit would need to be exposed, and the wiring would have to be disconnected and loose before attempting to pull the damaged wire out of the flex conduit.Replace the Wires
The section of these 14-2 wires that have been damaged will need to be replaced.Locate Each End of the Wiring
If it is possible to expose the full path of the wiring as it leads to the electrical boxes at each end then replace the entire section, otherwise accessible junction boxes will need to be installed at each location where the ends of the flex conduit is located.Identify Each Cable Set and the Wires
Be careful to identify each 14-2 cable wire set individually before cutting out any wiring, so the replacement wiring may be connected to the right wire set.
