I think this discussion has bogged down into too much
detail.
Overcurrent protection is required to provide protection
against overheating and fire (and sometimes shock) when
a fault occurs.
For plug-and-socket connected products, a mains fuse is
used to provide protection against LOAD fa

Chris Maxwell asks: "Can anybody shoot a hole in this theory with a single
fault condition?"
This subject has been debated before, on this list and elsewhere.
Safety is always relative. In the scenarios you painted, Chris, the phase
conductor always has an intact fuse after the neutral fuse open

I take some exception to the response below.
Single phase connections between phases either on a delta or wye system do
not have a neutral connection.
There are two grounded delta systems -- corner ground where one phase is
