T&B is giving you some misinformation then. If you read the UL link that Roger posted you will notice that it says fitting not connectors so this would include couplings. Anytime you enter the top of an enclosure you are required to use a hub or some type of seal between the connector and the enclosure even if the connector is listed for raintight application.

Anyone here spray their nuts with zinc to give a little extra protection?
Perhaps that's not what I wanted to ask. Does anyone here spray their EMT compression fittings with zinc?

Maybe the powder would work on the EMT compression fittings? ![[Linked Image from 65.108.216.53]](http://65.108.216.53/elec/zinc.gif)

Have used compression fittings and EMT outside for years and have not had a problem yet.
I saw this before on another site. I still feel that any one who is looking for a non issue to raise does not have enough to do.
For entrance to the top of a J box that is not threaded, I'll use a meyers hub. All the threaded type of boxes and fittings need is to be made up wrench tight. JMHO

Spoke with some people yesterday about The 'listing' of EMT fittings. Here is what UL says, which is a little tricky to understand, but I will try to repeat it.
As for the "2002 NEC" the current type of EMT fitting (which does not meet the 'new' standard) meets the 'old' standard and is acceptable to the 2002 NEC. That is why you still see the UL labeling on the boxes of fittings. As far as UL is concerned "RIGHT NOW" the fittings can be sold with the UL label.
By the next code cycle they expect to see the manufacturers making fittings to the 'new' standard.
I tried to keep it simple, the above is a 1 hour converation minus all the *^%$#@.
As far as I can see, the fittings can still be installed.I hope this helps.

Pierre did you follow the link that Roger put up? It is straight from UL and seems to contradict what they told you. From the link Roger put up Effective March 2002, manufacturers of UL Listed "raintight" compression type EMT fittings were required to comply with the more stringent follow up test requirements. If the manufacturers of these fittings did not comply with the new requirements, they were no longer authorized to mark their UL Listed fittings with the "Raintight" marking. Currently (April 2003), no manufacturer is authorized to mark their Listed compression type EMT fittings with the "Raintight" marking.
