Jag vill köra 1 "LV-ledning (Carlon Resi-gard) genom vinden. I stort sett använder jag vinden för den" horisontella "körningen från ett rum till ett annat.
Jag kommer att försegla hålet med lite caulking, men vad behöver jag mer veta?
Uppdatering till inlägget och för läsning. Detta är för Carlon
Följande är från här . Det var svårt att kopiera det på min skanner så jag kopierade och klistrade på den BÄSTA delen.
Godkända användningar: Typiska applikationer:
Exposed eller dold i byggnad över tre våningar när ett brand sprinklersystem är installerat i enlighet med NFPA 13-NEC 362.10 (2)
För användning i bostadshus upp till 3 meter över takets botten.
Uppdatering till uppdateringen. Innan någon säger någonting inser jag att jag gjorde ett misstag och jag faller på mitt eget svärd. Ovanstående gäller för Carlon Flex-Plus Blue, inte Carlon Resi-gard (Tänk att det är dags att gå tillbaka till ögonläkaren) så här är vad jag gjorde hitta . (Jag var säker på att OP sade flex plus)
PDF pekade på vinden men gick inte igenom, men det sa också att "Resi-Gard är klassad som en generell banan enligt National Electric Code (NEC) Artikel 770, för Fiberkablar och Raceways och artikel 800 för kommunikationskretsar ".Så med det skulle jag använda Resi-Gard i väggarna och Flex-Plus Blue för din raceway på vinden.
Jag har kopierat NEC-portionerna som täcker korrugerad HDPE-ledning (High Density Polyethylene) för din läsning. NEC skiljer mellan korrugerade och icke-korrugerade HDPE-ledningar genom att referera till korrugerad HDPE som ENT och icke-korrugerad som bara HDPE. Icke-korrugerad HDPE är inte tillåten alls i några byggnader, medan korrugerad är.
NEC särskiljer inte specifikt orange korrugerad HDPE från blå korrugerad HDPE utan hänvisar helt enkelt till fiberoptisk kabelledning som "Innerduct".
Listed plenum communications raceway, listed riser communications raceway, and listed general-purpose communications raceway selected in accordance with the provisions of Table 800.154(b) shall be permitted to be installed as innerduct in any type of listed raceway permitted in Chapter 3.
Även intressant är Carlon, tillverkaren av Riser-gard hänvisar till "Innerduct" när man jämför sina olika Riser-gard-produkter. Se här. Jag tycker att det är säkert att i allmänhet jämföra innerledaren med de säkerhetsbestämmelser som krävs för ENT-installationer.
De viktigaste delarna för dig kommer att vara 362.12 Användning tillåts inte, 362,30 Säkerhet och stöd för A-B och 362.26 böjningar.
Speciellt säkrings- och stödjande (B) adresserar dina horisontella vindsvängningar som tillåter spärrarna att stödja ENT om de inte är större än 3 'från varandra och förutsatt att du säkrar ENT inom 3' av varje drag / kryssruta.
Också intressant är 362,10 som endast tillåter byggnader som inte överskrider tre våningar för exponerat arbete.
Och allt över 122 ° F omgivningstemperatur är inte tillåtet om inte annat anges. Det kan vara ett problem för heta sommarhusar utan ordentlig ventilation.
När det gäller att borra i vindar som är mer en byggnadsproblem. Det här svaret adresserar koderna för det.
II. Installation 362.10 Uses Permitted.
The use of ENT and fittings shall be permitted in the following:
(1) In any building not exceeding three floors above grade as follows:
a. For exposed work, where not prohibited by 362.12
b. Concealed within walls, floors, and ceilings
(2) In any building exceeding three floors above grade, ENT shall be concealed within walls, floors, and ceilings where the walls, floors, and ceilings provide a thermal barrier of material that has at least a 15-minute finish rating as identified in listings of fire-rated assemblies.

Exception to (2): Where a fire sprinkler system(s) is in stalled in accordance with NFPA 13-2013, Standard for the Installation of Sprinkler Systems, on all floors, ENT shall be permitted to be used within walls, floors, and ceilings, exposed or concealed, in buildings exceeding three floors above grade. Informational Note: A finish rating is established for assemblies containing combustible (wood) supports. The finish rating is defined as the time at which the wood stud or wood joist reaches an average temperature rise of 121°C (250°F) or an individual temperature of 16.3°C (325°F) as measured on the plane of the wood nearest the fire. A finish rating is not in tended to represent a rating for a membrane ceiling.
