There are two types of shaver sockets available, those with transformers and
those without. Only the transformer socket can be fitted in the bathroom, because
the it isolates the supply from the mains, making it safer and suitable for
bathroom use.A shaver socket with a transformer must conform to British Standard
BS3535 to be suitable for bathroom use. Shaver sockets without transformers must never be
installed in bathrooms, but can be installed in the bedroom instead.
SWITCH OFF ELECTRICITY AT THE MAINS BEFORE WORKING ON EXISTING CIRCUITS
Shaver sockets can be install a shaver socket either by connecting to a ring main with a junction box
(see Adding a spur to a ring circuit from a junction box) or from an earthed lighting socket.
The spur from the ring main must be fitted with a 3amp fused connection unit before connecting to the
shaver socket (see Fitting a Fused Connection unit).
The fused connection unit should never be installed in the bathroom.
Connection from a lighting circuit can
be made directly, but must be earthed.
