Please explain your question in more detail and in as clear a manor as possible as we do not know what you are asking and anything we reply with would only be a pure guess.

OK. So how long does it take to walk to the switch, grab hold of it and turn it?

This still is too vague and general and means nothing to me, can you please provide more information and details on what you are after.

I agree with Jack. Your question is unclear. Are you looking for the code requirements for earthing the switch and disconnect per code?

Spec for an earthing switch and disconnector will depend on the voltage, short circuit current, position on the network (i e upstream or downstream fuses and/or CBs ).

Disconnector will be , on top of previous, rated current and number of operations.
