5" box

[qcroanoke]

Have never heard a
4-11/16 Box called a 5 inch box.
Until now I've never heard the term 5 inch box used in electrical talk.

If someone mentioned a 5" box, then it's most likely that they meant a 5" box.
For example:

Those things just look expensive!

I gotta wonder. Are there blank covers for 5". Mud Rings?

The confusion here is that an actual 5" box is a relatively new thing. Gonna have to change our slang terms to differentiate a 4 11/16" box from an actual 5" box.

That, or stop using so many slang terms.

How about an "information" box? (411)

Question. This is marketed as and listed as a low-voltage information box, not listed for use at normal line voltages, so it would appear to be not usable for "normal" 120/240/208 receptacle or j-box?

I noticed that, too. What is an information box?

What is an information box?

I made it up yesterday.

4-11/16 = 4-11 = 411.

Dial 411 for information.

4-11/16 = 4-11 = 411.

I should have said 'low voltage'.

Yes, you did. I totally missed it.

I miss so many things, it makes me gun-shy to post sometimes. I know me

5x5x2 PVC junction boxes have been around for a long time.

In some of the old city codes such as the 1965 Los Angles electrical code there is a section (90.0207 in the '65 LA code) that spells out "Information required on Plans or Specifications" paragraph (e) states that all boxes larger than 4 inches trade size need to be shown on the plans. Therefore a 4-11/16 box would not need to be shown on plans (still 4" trade size) but a 5" box would be, hence the popularity of 4-11/16 boxes.

Seems a little redundant to make both 4.6875-inch boxes and 5-inch boxes.
I think I just decided to never again buy a 4.6875-inch box, only 5-inch boxes.

Aren't these relatively new? I always called them 4 11 box.
