ECN Forum Forums General Topics of the Trade General Discussion Area Old Work Question

How do you comply with the code (314.17cx)when your installing a plastic device box in a concealed wall. I am not aware of a cable clamp for these types of boxes and how are you going to secure the romex 8 inches inside the wall? Is there a staple gun big enough for this? How do others handle comply with this?

Old work that is "fished" is considered supported. There are old work boxes available with integral clamps. I've used the plastic boxes and have never had an objection.

What about a light switch 48" from floor and you use a box with the built in clamp, your still required to have cable stapled to stud aren't you?

Not if it's old work and cable was fished.

See 334.30(B)(1)

Thanks, I looked for a while trying to find a code that dealt with this issue and couldn't find anything. Whats the secret to locating applicable codes for a given situation?

No secret. 600+ hours of code classes and a couple decades of referencing the book helps though.

"Whats the secret to locating applicable codes for a given situation?"

How much time you got?

Seachable CD works well.... And those memorable "wake-up calls" from inspections that went bad when I started out.

Four little words...

National Electrical Code Handbook.

It's the full text of the Code, with additional info giving examples and explanations of many of the FPN's.

It's not cheap...but it's worth every penny.

(Actually, buying the "pocket" Code book and the Handbook at the same time saves about 15% over separate purchase price.)

huh, didnt you have to take a test for lic.? and renew it every couple of years? I fint reading the post on here and looking up the question in the code book something to do, and dont just stop at first thing you find unless you all ready pretty postive from exsperience, keep looking for exceptions!!!
