I just remodeled a kitchen that was originally wired in the early '60s. Single story ranch style single family. The wiring I was modifying was mostly FMC. The original installers had used numerous junction boxes in the attic above the kitchen ceiling. All the boxes were on top of the ceiling 2x8 joists and mostly kept close to the rafters (to keep the center clear).

Then in the early '90s the house was given 20 inches more insulation. I had to tunnel through three feet of insulation to search for the suspected boxes [Linked Image]!!!

On the other side: If a j-box under insulation is inaccessible, is the outlet box that a luminaire is mounted over, that requires tools to get at, accessible?
