So with AMD1 out and everyone ignoring it I thought I'd spring a discussion about Surge Protection

Just watched this video where they blow things up

https://www.youtube.com/embed/r5PiCi5CAVI?feature=oembedHas anyone started installing SPDs?

I went into my local wholesaler to find out the cost of the basic hager SPD, which came to

 
Maybe best to completely analyse the requirements of the ammendment to discuss the full applications of when and what extent is requirerd. Individual SP devices are availrable where whole installation protection is not required. ie, commercial vs domestic applications.

Lots of info in new BGB on where, how and what to fit, but it does not seem to have changed much as far as I can see on WHEN they are required

 
does anyone know where we can get hold of the surge protection units to install in people's houses when doing CU up-grades
