Cable Standards and Selection

Chris Bailey

Hi 

Would be grateful for some guidance on cabling standards/selection

Currently developing an large energy storage system and equipment is coming from all over the place.

I seem to be struggling to get European suppliers of equipment to comply with British standard cabling such as shown in Table 4A3. I keep on getting thrown all sorts of weird and wonderful cable datasheets, all with IEC standards but no ref to BS or BS EN that I am comfortable or familiar with. We have clearly specified BS7671 as the standard to be followed but there seems to be a reluctance to adhere to this.

Example

Power cables 2XY-fl RM 2x2,5mm² (bk)

Instrument cables   RE-2X(St)Yv-fl 1x2x1.0mm² (bk/bu)

Would other non BS cables be accepted in the UK and signed off and what are the implications in not following cable recommendations in table 4A3? 

kind regards

Chris

    There is more paperwork to be done ("justification" as per 511.1 and 511.2) where the cable is not to a British or Harmonized standard (usually numbered "BS", "BS EN", "BS IEC", "BS EN IEC" etc.).

    The use of the particular cables (preferably with a reference to the justifications) should be included on the electrical certificates ...
