I looked at a job and in the attic vandels cut and stole a bunch of wires.Im thinking how to handle this job.Trace out the homeruns first and mark them.Then trace each cut wire to see what its connected tf course alot of j-boxes.It doesnt seem like a good idea to mount the j-boxes on the joists.Iwas thinking nail some 2x4s vertically so i can mount the j-box to it and so no one will step on them.Any suggestions?Thank you.
