SPD Location In this setup.

Good Evening.


Not posted on this new forum yet, had to re-register as it didn't seem to bring my account from the old forum across.

I have a requirement to fit an SPD on this installation. Where would you think it is best to situate the SPD? I know it should be no more than 0.5m but in this setup, would it be best half way up straight off the henley blocks? I plan to fit an enclosure with a SPD and MCB to protect it.


Unsure at the moment if that DNO incommer is 2 phases off a 3 phase transfomer or split phase at 180deg / 480V, we have not started work on it or tested anything yet. Just at the quoting stage.


Many Thanks.

    Many thanks for the replies.


    So where are we actually saying the 0.5m rule applies too? Is it max 0.5m off the load side of the meter or 0.5m away from any point in the tails?


    Chris, yes it is a lovely job they have done, lovely to see some one take pride in their work. I know who did it and I’d love to employ them but I think they are happy with the current company they work for. There are sadly a few things that don’t comply but I’ll be correcting them to the same standard. Like it is TT but there is a lot of metal bits the tails come into contact with before any RCD. I plan to fit and adjustable setting, adjustable delay main RCD before that main isolator.
