I thought a
"gang"
was a 'socket'. So a single gang power point has a single
plug
socket, whereas a dual gang cat5 point would have 2 ports but
obviously fitting within a standard UK sized single
socket...
Have I made
this
up??
But you get 1G, 2G and 3G light switches, in
1
and 2 ways - all in a single size box..... then you get 3G
sockets
in a triple width.... weird - go figure!!!
I
can confirm that the Screwfix ones are single back box width (like a light
switch) and can take 2 RJ45 modules.
