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

  • Have you any thoughts on the overlapping of BS7671 / BS EN 60204-1

    Others here will know the intricacies between standards better than me, but as I read it there is no overlap - if BS EN 60204 applies then it's out of scope of BS 7671 - see BS 7671 reg 110.2 (xi).

    Absolutely ... except where BS EN 60204-1 refers to IEC 60364 or HD 60364 (i.e. BS 7671) Grin
