Farmboy over 5 years ago

Hi all

Does anyone have a copy of the graph / curve please, either on its own or perhaps along with a 60A curve?

Thanks

but just for giggles thought I'd give the adiabatic a spin.

Provided Ze is reasonably low it'll likely be more than adequate - I think I remember one case here of a 2.5mm² earthing conductor on a TN-S system and it was shown to comply! Nevertheless a good exercise to do!

I think Mike might have posted what you want on the old Forum: https://www2.theiet.org/forums/forum/messageview.cfm?catid=205&threadid=64556 in his post of 14 March 2016 09:08 AM.

Thanks for this Andy and Mike, much appreciated.
