And don't they call it "mesh" or something like that, when it's applied to a pcb?The practice of Equi-potential bonding is now also used in Industrial enclosures & machinery etc, in order to eliminate ground loops.

Not sure? I call it a 'ground plane'And don't they call it "mesh" or something like that, when it's applied to a pcb?
The domestic equivalent of a ground plane would be living in a shipping container!Not sure? I call it a 'ground plane'
WRONG! "earthing" an item, only if it is done correctly, will prevent that item from supplying a shocking voltage, BUT it will assure that if some other item becomes charged that the earthed device will provide the connection to complete the shocking circuit.So, is a. Kindof earthing. Is it not?
if proper earthing is given, you need not need rcd. Is it correct?
It's like the bird on the electric wire - if everything it can touch is the same potential, it's safe, even though it's all 6.6kV!

We are seeing combination AFCI/GFCI combination breakers in America. (Arc Fault Circuit Interrupter). AFCIs are now being required by code for certain circuits.30mA is the most common rating, though 10mA is available from RS, but not the average electrical distributor.
Are RCBOs getting common in other countries? (Residual Current Breaker with Overload) It replaces a MCB in the consumer unit (fuse box) (and makes a mess of the neutral wiring in the box in the process)
30mA won't prevent a shock, but will prevent it from being fatal in most circumstances.
A RCD at the outlet won't protect the installation from failing insulation in the cables.
