ADS

Coby:

It is very strange that a group of electrical engineers would get together and decide to use earthed equipotential bonding in order to limit touch voltages, then call it earthed equipotential bonding and automatic disconnection of supply when they saved you all of this confusion by simply calling it earthed equipotential bonding and the limitation of touch voltages!



 

They don't call it EEBADS any more. It's ADS now - and has been since 17th Edition in 2008.


The error in terminology has been corrected.


Earthed equipotential bonding is part of ADS and is used to limit touch voltages between exposed-conductive-parts and extraneous-conductive-parts. Importantly, there is no guarantee that main protective equipotential bonding will limit touch voltages to a non-hazardous level - that doesn't come in until you use supplementary local equipotential bonding.


Supplementary local equipotential bonding is used to limit touch voltages between exposed-conductive-parts and between exposed-conductive-parts and extraneous-conductive-parts of the location in the event of a fault, either because it's a special measure for additional protection implemented by a Section in Part 7, or as a measure where disconnection times for ADS in accordance with Chapter 41 cannot be met, or where the designer opts to use it for additional protection for some other reason.
