Danger is more for plugged devices due to the flex used.Guess so, but I can't see the danger being more or less for a fixed 63 amp device vs one on a plug.
Danger is more for plugged devices due to the flex used.
Fixed loads are usually installed via flexi conduit, armoured cable or similar heavy duty cables.
Plugged in devices usually end up with fairly unprotected trailing leads.
No,I guess that means added impedance increasing disconnection times?
Socket outlet is a final circuit.Final circuit or dis circuit is the question.
...except when it's plugged into a distribution boardSocket outlet is a final circuit.
Wow! "Have DB, will travel"...except when it's plugged into a distribution board
No,
Likelihood of damage to cables.
Rcd are for the protection of persons, not equipment.
Trailing leads, associated generally with plugged in equipment tend to get damaged exposing cores, or potential short circuits.
An example may be a 63A welding set, loads of steel plate being moved around, and potential for dropping plate sharp edge-on to the welder supply cable.
Fixed equipment tends not to be like this.
See post 2To me that would mandate RCDs instead of reduced disconnection, but what do I know? ?
See post 2
Both aspects are being brought in line.
Sort of, the cooker example is unlikely to fall within this range (unless industrial, or especially large), but yes there could be loads which are final circuits between 32A and 64A where being hard-wired or plugged in would make such a difference.Alright.
So double checking that would mean a hard wired cooker could get away with 5 seconds, but a flex cooker would require 0.4 seconds? In the US almost all cookers have plugs on them.
India. An interesting place to work with electrics (as I have)...... least said about their 'standards' the better, I feel.My understanding is that in India, all final circuits are required to disconnect in 0.4 seconds or less. Personally I like the idea.
An exception for 5 seconds is needed for sub circuits though- 60 amp life safety feeder must selectively coordinate with the final OCPDs.
Not so much the standards, but any sort of compliance to them!India. An interesting place to work with electrics (as I have)...... least said about their 'standards' the better, I feel.

I get the impression we may have differing experiences on this one. It was in India (Mumbai, to be exact [though other places and experiences also exist]) that in a 5* hotel I enquired why the earthing had been removed.... “because if we put it back on all the trips go”.India has one of the most beautiful electrical systems on earth, minus all the DIY of course.
