Horse Barn Wiring?

A horse barn has a SER feeder from the home, underground sleeved through pvc. Does 338.12(A)(2) prohibit this? Also should the conductors be copper 547.5(A) 547.5(F)

Is EMT permitted for the interior wiring? 547.5(A) does not list EMT but does permit other cables or raceways suitable for the location.

Thanks you in advance.
 
from the ul guide information
http://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/showpage.html?name=TYLZ.GuideInfo&ccnshorttitle=Service+Entrance+Cable&objid=1074120731&cfgid=1073741824&version=versionless&parent_id=1073993944&sequence=1
Type SE ? Indicates cable for aboveground installation. Both the individual insulated conductors and the outer jacket or finish of Type SE are suitable for use where exposed to sun. Type SE cable contains Type RHW, RHW-2, XHHW, XHHW-2, THWN or THWN-2 conductors.

An AHJ could approve it but it is not listed for underground applications.

Emt is not prohibited from being used ,... I would not use it any where a horse can reach and I would not use it where they eat, drink, pee and poop

 
more info is needed..like you say the SER is sleeved to me that means it is direct buried and sleeved where it exits the earth..other wise it is installed in PVC conduit..but either way it is wrong as PVC conduit buried will collect moisture due to temp changes alone..I would have no problem doing the general wiring in the horse barn with EMT..I would not use it in the horse confinement areas though..Only in the ceiling for lights..something about a horse being very destructive..I have seen some very bad condiment areas where the walls are damage the floors are all tore up and dug very deep..but that leads me to believe the horses were neglected..different issue..
 
I agree with both of these guys. I have used EMT in horse barns before, but only on the high stuff that they cannot reach. Also the SE cable is not permitted underground. The NEC made that clearer in 08, but it has been in the UL white book before that. I have seen some AHJ's let it go though.
 
I use pvc due to the fact that horses do not tolerate current at all, does not take much to kill a horse. A bad electrical feeder leaking current somewhere will go right thru a horse to a well grounded piece of emt. something about standing around in @#$& makes for a good conductor.
 
I think one thing that we often overlook is that a horse barn would fall under 547, IMO. This means that the following are the only approved methods of wiring. Se cable must be copper. Nec 2008

547.5 Wiring Methods.
(A) Wiring Systems. Types UF, NMC, copper SE cables, jacketed Type MC cable, rigid nonmetallic conduit, liquidtight flexible nonmetallic conduit, or other cables or raceways suitable for the location, with approved termination fittings, shall be the wiring methods employed. The wiring methods of Article 502, Part II, shall be permitted for areas described in 547.1(A).

Dennis are you saying that EMT is not approved..or would you say it is an ahj call..I was at this place the other day and it was a horse arena and stable..it had dirt floors..wiring was concealed and what I could see was NM wiring with plain old florescent strip lights..I notice the wiring coming down the pole was not in a sleeve and was normal 200 amp 4/0, 2/0, 4/0 aluminum tri-plex. I did not notice a sticker any where so must of been done by owner..

I ain't saying nothing :grin:. I am just reading what the code says. It appears art. 547.5 references 547.1(A) which I believe to include horse barns so then art 502 part II would also apply. Art 502.10(B)(2), (part II) allows EMT

I most definitely agree with it being an agricultural building..I do not know if I would go as far as saying it is combustible dust..I do believe it will accumulate the 1/8 inch of dust but I do not believe it is combustible just corrosive..
