Conduit VS sleeve

[220/221]

The interior of a 3R enclosure, below the live parts may is a wet location. Why else would that enclosure have drain holes?

OK......half the time I can't tell if you guys are joking. Use a smiley face or something:smile:


.....below the live parts (may?) is a wet location???


If you are serious, how is the bottom part of an open box wet while the other remains dry? If you were joking..you got me

As any plumber can tell you, water flows downhill.

Not in the Southern Hemisphere. Everything is opposite down there.

From the NEMA site:
Type 3R Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow); and that will be undamaged by the external formation of ice on the enclosure.

The standard does not require that the 3R enclosure not get water on the inside, only that the water not get on the live parts or interfere with the operation of the equipment. 3R enclosures have drain holes in the bottom to prevent the accumulation of water within the enclosure.

If a conduit with rain-tight fittings is allowed to enter this enclosure above live parts (312.2) and this installation ensures that water will not get on the live parts, does it make any sense to automatically classify the inside of that conduit as a wet location?

Unlike conduit that does not have drain holes and can certainly contain accumulated water that would never drain and thus present a wet location.

We go the Home Depot and buy any length of thhn/thwn in the colors needed and install them per N.E.C., What's so hard about that. Buy Stranded for this purpose. It goes in easy and won't break at the splice due to vibration.:smile:

Welcome to the forum David.:smile:

Nothing is hard about that.

But here at an NEC forum that is really not the point. If you hang out here you will see we discuss things for a long time trying to figure out what the NEC actually requires.

You will see many of us talking about what the minimums are......that has nothing to do with how most of us work.

Hey, that's (at least) 1/2 the fun!

We stock wire on our trucks. What's so hard about that?:grin:

Most times the answer is never found and the topic strays into a pointless abyss of useless information. Enjoy! :grin:

Not meant to offend - IMO nothing says "landscaper" like the word "sleeve"! The word just makes me wince - in way similar to the word "Wiremold" which no matter how it is said - sounds like my mother whining about taking out the trash when I was a kid. The info is only useful to understand my psyche for what comes next....

If you piped it (with conduit I assume - not plumbing fittings?) - why not pull in the right conductors, as it would be so much easier that trying to stuff a cable trrough it.
