4" Box 6p?

How would you meet this requirement for a 4" lighting outlet or switch box? :? THanks.

One could contend that a box for an outlet or switch is neither a pull nor splice box.

But there is a splice in a 4" box so technically isnt it a splice box?

If I recall right, you cannot install a switch or an outlet in a pull box or splice box.
however, you can do a splice in an outlet or switch box.
and, then there are the pull boxes that are not large enough to do splices in.

but I am just a student, so could be wrong...

Open to interpretation.

I’ve always thought of a splice box as a box that is installed only for the purpose of making splices. The fact that a splice is made in a device box does not make it a splice box.

I wouldn’t die on the hill defending that!

I don’t see how you would mount a receptacle or switch on a 6P box. You are talking boxes with bolted covers and gaskets that are rated for submersion in water.

Bingo. 6P means submersible. Why are you concerned for how you are going to wire an outlet under water? Switch, maybe; you can get 6P rated switches in the industrial world. But lighting outlet? No.

What is DFE?

What is DFE?

Design Flood Elevation, basically an area classified (by FEMA) as likely to flood on a regular basis.

BFE is the Base Flood Elevation, a higher level based on the "100 year" flood event.

Actually I think I got that backward a little, DFE includes the BFE plus some. But nonetheless, it designates an area that might be flooded. That specification note on the drawing is saying that anything that is going to be wired in that area must be made up in submersible enclosures, which also means sealing the conductors going in and out. I doubt you can put lighting in those areas at all, unless you maybe use marine type fixtures designed to be submerged. In places like St. Petersburg FL where I have done some work on new condos, the ground floors up to about 6' are all DFE areas, nobody puts electrical in there, too expensive. Light fixtures in the ceiling are OK because they are above the DFE, but you see a lot of them using pull chains, not wall switches.

Thanks. We have fixtures in the cellar that are below the DFE.

Thanks. We have fixtures in the cellar that are below the DFE.

Then the fixtures would have to be waterproof, ie marine duty, all wiring in sealed rigid conduit, all devices submersible. In reality you are only supposed to put minimal electrical systems for life/safety in areas below the DFE.
