That’s how I interpret it.

Not sure how you can carry out a risk assessment however because it states that you have to do a calculation with the different lengths of each element of the distributions various cable lengths.

Lpal, Lpcl, Lpah & Lpch

Other than asking the DNO not sure how these can be determined.

So I guess the only real way is to add type 2 devices to each CU adding £200+ to each job?

443.4 continues with a catch-all, after (i) through (iv) are satisfied, by detailing an exception to the requirement being "single dwelling units where the total value of the installation and equipment therein does not justify such protection". Personally I can't see many exceptions, when considering the small price of installing this protection, ultimately this would be the insurer's call and I imagine it will not be long before buildings and contents policies stipulate SPDs as a requirement in their T&Cs.

you have more chances of being kissed on the lips by a giraffe.[/QUOTE]

I was kissed by a giraffe once when I was a kid on a visit to Flamingo Land Zoo many years ago. It lent over it's enclosure fence and reached down to me. I thought it was going to let me stroke it's head but it gave me a smacker on the forehead which is just as well as I wasn't into all that :confused:French kissing stuff at that age!
