The guy was right. I connected the green and brown wires to the terminals (2 and 5) on the front plate and the extension socket now has a dial tone.
Hi does it matter whether you connect the brown or green to number 2 and 5 and is it difficult to get them connected to the numbers
Who is your line provider?
it is quite common in extension socket where the incoming wires and outgoing wires to another extension are connected to same 2&5 terminals. I.e. Extensions connected in series
@Clairec: If you are asking about the master socket there could be more than 1 pair of wires connected to terminals 2 & 5; 1 pair for each live extension in the home. I.e. Extensions connected in parallel.
