TN-S Earthing system for Lift main supply

Aroi Rodriguez

Hi All,

Quick check if the following proposal is okay.

The design specifies a Multicore XLPE cable 4Cx25sqmm + 1Cx16sqmm CPC for the main supplies of a lift in a Data Centre. 

The construction team has installed a Multicore XLPE/LSZH cable 5Cx25sqmm.

Would it be any issues with utilising a 5C cable rather than a 4C with a separate CPC?

Regards,

Aroi

    No, but there is a cost penalty! Is this SWA, in which case the armour is probably satisfactory as the CPC, and would be normal practice in the UK.
