I see that many suppliers now offer both SP and DP versions of switched
sockets, with DP up to 50% dearer for a given make.
What governs which version one should use?
I'd prefer DP, as it means the appliance can't trip the RCD when the
switch is off.
With SP, an N to E short in the appliance could still cause a trip
even if the socket is switched off.
