Zs

[keniff]

Hi, when Installing a fused down spur off a rfc, do you record the max zs for the 32a mcb or the bs1362 fuse? Had different opinions on this!

So furthest point would be the light in this case, max zs would be 1.93 for the fuse and 1.15 for the mcb, iv always had mixed replies on this just thought I would start a debate! I have always tested at the end of the circuit even after a spur if I'm honest

Sorry it's a fair question I hadn't read it that well tbf, I'd still put the mcb personally as that's what's protecting the circuit, maybe I'd use the higher permissable value if I couldn't meet the lower one
