CRL risk asseament.

[APE37]

Hi guys,
Anyone know of any templates for risk assessments for spd protection? Been reading up on it and been told I need a crl risk assesment. If anyone can help that would be great.
Cheers

It is all detailed in BS 7671:2018. It is a very simple calculation with examples.

@essex is correct, but I doubt you will find anything that 'passes' and doesn't need one. I've given up and just sell the SPD - they are under £60. It's not the calculation, it's the documentation of the the customer refusing (NAPIT now have a special form for this) to cover your/their arse. At the end of the day... IF over voltage caused damage, the customer will bleat that you didn't 'explain' it properly - especially when their insurance won't pay out because you have documented that they opted out!
