Hey Bob thanks I know the section but have I been misinterpreting it? 312.2 above the "level" of uninsulated live parts, even entering the side above live parts. If I have done a misinterp, I will post my "home address" for all the EC's to send cards and letters.....:smile:

It is rated for use in wet locations, so is a compression conduit connector, but it still needs a way to seal the entry into a cabinet.

I think I will just call in sick.......for about a year..:D Just kiddin. I still feel strong about it and the EC's have not argued. But if I am not accurate then I will change my way of thinking on that issue.

Chris when you buy a TA does it come with a lock nut?

No.

A TA is intended to be screwed into a threaded hub and when used like that will be WP

But when you use a TA with a locknut directly to a sheet metal enclosure you must do something to make a seal to the enclosure.

Just like you have order a lock nit you will have to order a sealing ring or ask for a sealing locknut.

Personally I try not to enter the top of WP enclosures, if there was room I would have come down beside the switch into a trough and then into the bottom of the switch.

Good point.

My perfect world comment is in reference to the following 2 Arts.

230.8 Raceway Seal.
Where a service raceway enters a building or structure from an underground distribution system, it shall be sealed in accordance with 300.5(G). Spare or unused raceways shall also be sealed. Sealants shall be identified for use with the cable insulation, shield, or other components.

300.5(G) Raceway Seals. Conduits or raceways through which moisture may contact live parts shall be sealed or plugged at either or both ends.

Given the construction of todays enclorsure and the fact that duct seal doesn't work very well, it has been my experience that unless you have a high quality NEMA 4 some moisture will be present inside.

I wouldnt miss it for the world. I wired for over twenty years and what I like about this Forum is let's take an average of interpretations....ya gotta love it. Although I work for an AHJ......that does not mean I agree with them.

Help us out here because I can't see what you're getting at for the installation example posted. :-?

Chris mentioned that he does not glue the fittings for PVC for short sections of installation (this is how I understand what he is saying).

I was pointing out that the two sections I mentioned require securing the raceways/cables/wiring methods to the respective enclosure types.

So the last paragraph of (B). The glue secures it?

From an inspector's viewpoint, violation or not, sealing issues aside....and be practical. Speaking here of the nipples he installed between the cabinets.

I agree and I also agree with your thought about the cement securing the raceway to the boxes.

If there is no cement then they are not secured to the enclosure.

But the CT cabinet and the disconnect are not covered at all by Article 314, they are covered by Article 312.
 
Chris how about switching to Box Adapters in place of TAs.

Two of the box adapters with a coupling could work as long as you spaced the cabinets apart to match the coupling.

While looking I also notice Carlon sells these

I use them but they have thier place. They usually have to be cut shorter and thats a PITA. Also hard to get a water tight seal.

For $2 each I'll be asking the supply house about them.

Thank you.
