Advice needed On 18th edition boards. When do fit SPD boards?

[AJshep]

I generally install them in dwellings, I do give the customers the choice though, but honestly though if you tell them there have been rumours of insurance companys are using surges to get out of paying for damaged electrical equipment they usually just tell you to put them in.

If they dont want it, just get them to sign a letter, just take a copy and attach it to your EIC.

443.4 refers and uses the term ‘shall be installed’. Basically if the installation has electrical equipment over the value of about £200 BS 7671 states SPDs shall be installed.

To paraphrase (without getting BS7671 out for exact wording), the requirement is essentially that where the value of equipment warrants it an SPD should be fitted. (This would require discussion with the Client.) It does not necessarily mean that where the value of the equipment exceeds the cost of installing an SPD that it must be done. I don't believe that is what is intended by the wording.

The value of anything can only be decided by the owner of it surely.....

Don’t start me, what with your fancy common sense and all ...

I spoke to the NAPIT inspector today about this issue and he suggested that on a dwelling if it is overhead cable or has a lightening conductor you should insist on fitting SPDs otherwise offer it to the customer and if they refuse the extra cost just write it up on the cert.
BTW I'm new here though, unfortunately, I'm not new to the electrical industry and have had my own business for 34 years. I passed my 18th edition way back in august with 92% and I received the same advise on the course.
I'm just in the process of changing registration from the NIC to NAPIT and it's doing my crust in.
