Power Cables and CAT6

AncientMariner
A friend is looking to get both power and internet into an out building.  Rather than overhead the internet via external grade CAT5 or CAT6, I said, what about using armoured CAT5 or CAT6 underground?  His response then being, can I pull both power and CAT5/CAT6 through the same underground duct?  It would be about 10 metres.


To me sounds unwise, so would appreciate comments.


Many thanks.

    I would certainly consider it to be Band 1 comms cable. Similar to my earlier point made about a Band 1 cable which could be run in a seperate conduit indide the same duct to maintain the 100mm seperation from a Band 2 cable. 



    The regs states - where this is not possible, either of the two options detailed in Regulation 528.2 of BS 7671should be fulfilled at the relevant point. These options are:



    • a fire-retardant partition is provided between the cables. This might be, for example, bricks, shaped blocks, protective cable conduit and the like, or

    • where cables cross, mechanical protection between the cables is provided. This mechanical protection might include conduit, concrete cable protecting caps or shaped blocks.
