Osp Cable

[enrique santiago]

Hi guys,
I am on the middle of an inspection and the inspector fail me because i use plenum wire from the wall to the floor oulet for an POS (cashier inside of the building on a retail store). His argument is that on Orlando FL we are required to use OSP inside of the building. I alway use OSP outside of the buildings but i never use it inside. at the report card he is just calling chapter 800, no details. I am Missing somethig here? I really will appreciated your comments on this topic.
thanks

Let me get this straight... they want you to use Ouside Plant Cable inside? That's bass ackwards from the way it should be. Normally, guys get caught sneaking in bits of OSP cable indoors .

yes, this inspector want OSP inside of the building and the argument is that because is a floor outlet it is a wet location. Is any on the city of Orlando code that cover this situation?

OSP would generally = no. You can get outdoor (flooded and not) cat5e with CM or CMR rating. I dont see why he cares though.......

800.50 Listing, Marking, and Installation of Communications Wires and Cables.
Communications wires and cables installed as wiring within buildings shall be listed as being suitable for the purpose and installed in accordance with 800.52. Communications cables and undercarpet communications wires shall be marked in accordance with Table 800.50. The cable voltage rating shall not be marked on the cable or on the undercarpet communications wire.
FPN: Voltage markings on cables may be misinterpreted to suggest that the cables may be suitable for Class 1, electric light, and power applications.
Exception No. 1: Voltage markings shall be permitted where the cable has multiple listings and voltage marking is required for one or more of the listings.
Exception No. 2: Listing and marking shall not be required where the cable enters the building from the outside and is continuously enclosed in a rigid metal conduit system or an intermediate metal conduit system and such conduit systems are grounded to an electrode in accordance with 800.40(B).
Exception No. 3: Listing and marking shall not be required where the length of the cable within the building, measured from its point of entrance, does not exceed 15 m (50 ft) and the cable enters the building from the outside and is terminated in an enclosure or on a listed primary protector.
FPN No. 1: Splice cases or terminal boxes, both metallic and plastic types, are typically used as enclosures for splicing or terminating telephone cables.
FPN No. 2: This exception limits the length of unlisted outside plant cable to 15 m (50 ft), while 800.30(B) requires that the primary protector be located as close as practicable to the point at which the cable enters the building. Therefore, in installations requiring a primary protector, the outside plant cable may not be permitted to extend 15 m (50 ft) into the building if it is practicable to place the primary protector closer than 15 m (50 ft) to the entrance point.
