I'm not very clear what answer your original question was intended to elicit.
It is important to see that the EEB and ADS principles are really two distinct concepts, both for safety, but working independently.
EEB first. We connect together all parts that are simultaneously accessible, that are either earthed or credibly could come live in fault ( so not door handles and toothbrush holders) so that if there should be some fault that makes one live, they all go partly live together while the fault current is flowing, but the voltage felt by anyone unlucky enough to be in contact is limited to a safe level - the idea being that the fault current may be hundreds or thousands of amps, but the resistance between adjacent parts is tens of milliohms.
If the EEB is good enough you do not need the ADS, until you step out of the equipotential zone, and touch something that is either live or earthed but not bonded.
.
ADS second. We'd like the power to be cut if there is a fault, without a person having to flick a switch to do it. That is it. Automatic Disconnection of Supply.
Many devices count as ADS, expulsion fuses, fuses in plugs, ACB,MCCBs, MCBs all detect an over current, and NEED a solid path if you'd like them to operate on earth faults. They provide no protection to the man on the grass holding a cut lawnmower flex, as the body resistance is much too high. RCDs and RCBOs all achieve ADS for earth faults by looking at the difference between live currents going out, and neutral coming back - if the round trip sum indicates that some current has got off sideways somewhere then well have that automatic disconnection please. This can be made sensitive enough to save the man in the garden, as now we have decoupled the load current in the L-N loop from the shock current in the L-E loop.
As soon as we have RCD for ADS the EEB aspect , which we could never fully achieve outside anyway, becomes much less important. At the first hint of a small shock current pop goes the weasel RCD.
