Existing wiring was found right where I am installing a new outlet and is preventing the new outlet box from being positioned correctly. I do not want to change the outlet location. My plan is to deenergize the existing circuit, temporarily protect the Romex from abrasion, and then hog out the pass-through hole in the stud to allow the wiring to drop down ~1". The box can then be mounted flush with the drywall.
What can I use to protect the Romex while I am drilling the hole bigger? I am thinking of holding the wire up, inserting a small piece of metal (like a kick plate trimmed to fit in the opening) just below the wire, and then safely drilling the hole. Any other ideas?
