Morning all,

I'm currently finishing off my Lvl 3 C+G and I just need to finish off my design spreadsheet then I'll have completed it. I've one last column to fill in "Max Zs @80%" the design is based on a hotel using a TN-C-S supply. I'm just wanting to know where I can find this information in the On Site Guide.

Thanks

The values in the OSG for max Zs are already adjusted. As Westy said regards BS7671 you have to multiply those by 0.8
