Evening all
Is anyone fitting surge as standard in domestic property’s?
We are based down in Dorset which has 3 different flash density’s!!
So I always base is on worse case with most of our stuff being in urban areas and always unable to confirm length of supply cable! My calc is usually;
Urban 850/(1x0.50) = 1700 No SPD
Rural 85/(1X0.50) = 170 SPD
Thoughts?
