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.

    Thank you for your replies.


    I am looking to use it as an alternative to SWA cable base on ease of installation and coat in commercial installations.


    Andy Lewsbury - I understand the concept of  I2t/K2S2. And I agree that the restriction to limit the circuit protection to B Type only is an overkill. The cable is to be clipped direct on the walls and supported on cable tray/basket containment with a low risk of penetration.


    Sparkingchip - I am looking at the BATT Cable Data sheet for their Guardian XLPEAli tube LSZH Cable and they provode current carrying capacities for Reference 11 (on cabe tray) . I am interested to hear which manufacturers data sheet you are looking at?


    I was recently told by a contact on Linkedin that manufacturers have undertaken improvements to the cable and that the B Type requirement had now been relaxed. However, I cannot find evidence of this on any manufacturers website .




    What about asking the manufacturers tech dept for their view?
