Lightning conductor bonding

Pete999 · Sep 19, 2013

Always bothered me when bonding the Earthing system in a building to the lightning conductor installation, it seemed odd to me. I went to Elex today and attended an NICEIC seminar about earthing, apparently Tony Cable is saying it's OK as long as you install a surge protector unit between the Lightning system and the earthing system, any thoughts????

what the ---- is a surge device going to achieve on an non-energized earthing system lol ?

well if Tony the big nic kahuna said so it must be kosher , could be an all new type of pyhsics the schemes are developing.

He reckons it will stop any spurious currents coming into the building resulting from a lightning strike.

sounds to me like more "cable cobblers".

This makes absolutely no sense to me. Are you sure this is exactly what he said?

absolutely even showed a slide with the diagram

I still think you might have misunderstood. By all means install surge protection on the incoming supply in the CU but please don't start installing surge arrestors anywhere near the lightning system.

It's always seemed odd to me, that so many know so little about earthing and bonding. So it comes as no surprise to me, that the same applies to bonding lightning protection systems to the buildings MET!!

Someone has got this surge protection location very wrong!!! lol!!

It's always been a complete mystery to me why it is a requirement to main bond lightning conductors anyway,given that they generally are outside the equipotential zones....if anyone cares to offer an explanation......?

You could be correct I was stood at the back and I am 68, and wearing specs, so maybe I did get it wrong, anyway not to worry I'm only on the sidelines now don't do any work as such, just interested in all the latest developments, but I'm sure that's what the two guys on the podium were saying.
Great Forum by the way

If you want to know a bit more about lightning conductors, their use, and relevance to BS7671, then Dehn are doing a one day course in Birmingham on Oct. 22nd for £60, inc. dinner.
See the details on their site.
