Thanks for the replies.



I have some on the floor and some in the ceiling area, so will handle

Out of curiousity, what exactly are you doing? Unless you're changing
the wiring for some other reason, there is no reqt that you bring an older
attic up to current code. If it was compliant when it was put in, it's
still compliant today.

If it were my attic and there was something glaring, like a cable you
could snag, in an accessible attic that you use, I'd fix that. But if it
looks OK and isn't causing problems, I wouldn't rewire just to make it
comply with code today.
