8. Attach the Nest connector
Each cable coming from the ceiling or wall
will have three or four differently coloured
wires. Their colours may vary based on
their age.
Match the live wires coming from the
ceiling to the live wires in the Nest 230 V AC
connector and put them into a connector
block. All the neutral wires go into another
connector block, and the earth wires into
a third terminal block. There is no need for
the Interconnect wire, as Nest Protects
are wirelessly interconnected. If there’s an
interconnect wire, insulate it.
Live wire (brown or marked L)
Neutral wire (blue or marked N)
Earth wire (yellow and green), if present
Interconnect wire (usually black), if present
