BS 8436 Cable

Jonesy
Hi all I am new to the Forum.


I have a question regarding BS 8436 Compliant Cables. I am aware iof the requirement to protect circuits wired in BS 8436 Cables with "B" Type devices etc due to the requirement to limit fault current in the event of the cable being penetrated by a nail or a screw. However, what if you install the cable clipped direct to the surface and on Cable Tray or basket where the risk of accidental penetration is very low, would it them be acceptable to protect the circuit with "C" Type devices?


I have hunted high and low on the internet for an solution but have failed to find a definitive answer.

    Hi Weirdbeard.


    To be perfectly honest no I haven't contemplated the use of HiTUFF. 


    I was trying to get away from the black industrial look. I am looking to use the BS 8436 Cable in Commercial installations.


    I have recently spoken to Prysmian Technical Department who were very helpful. They referenced the BS 8436 Document where it stated that only Type B MCB's to BS 60898  can be used with the cable.


    So I am resigned to design around B Type breakers for lighting and small power circuits which may not be a huge problem and look for alternative cables for supplies for items such as gas interlock panels etc.


    Thanks for your input.
