hi all, been to a house today, friend having a problem with 2 way lights in room consisting of 2 x 2way switches after decorators been in. being taught the way by using 1 pair of strappers was baffled to find 2 pairs, anyone shed some light on this?

yes full apprenticeship with N.G.Baileys but been on Sub-stations for past 4 years. so been away a while. just set up on my own
 
Could it have been an intermediate switch?

Are you oop north if Baileys trained you?

Are you saying two wires in L1 and two wires in L2 and nothing in C?
 
yes there was a single in each common. feed and switch but 2 pair in l1 and l2. spoke to a friend an he says its the same on his stairs at his house but dosnt know why? i know of no other way apart from 1 pair.
 
Bailey's are in Yorks, aren't they?


I think what you have seen is a twin cable + 3 core in one switch & a 3 core at the other, where in the switch with two cables, there are two wires in each of the strapper terms.
