Wylex REC2SPD

Will Elec
Hi all,


I bought one of these for the first time today for a job I have coming up. I was suprised when I opened it up to find the SPD linked to the isolator by just 2.5mm wires, as these are the factory connection I guess this is the norm but I was suprised all the same! Why so small? I was expecting a copper busbar!


Thanks,

Will

    Humm 2.5mm² does seem a bit smaller than I would have expected - hardly in the spirit of 534.4.10 (although presumably these will be covered by the product standard rather than BS 7671). Maybe it says something about the size of surge than the manufacturers think it'll be able t cope with.  It even seems a bit thin for ordinary fault protection given that the upstream protective device is likely to be the DNO's fuse at anything up to 100A.
