2 way switching

[Mac]

Can anyone tell me what the difference is between 2 plate and 3 plate wiring for a 2 way lighting circuit.I was wiring a 2 way lighting circuit in single core cables.Looped in and out at the light,took switch line up to light,started to pull strappers in,and the bloke i was working with said you can wire it in 2 plate.Remember doing it 20 years ago,but can't remember how it was done.Watched how he did it,but it didn't look right.

Sorry mate never heard of the plate term for two way.
Exactly what are you trying to achieve.

hi 3 plate ie ceiling rose
are you talking about the methods for 2 way ie switch line from rose 3 core + earth to 2 way switch
or
conduit line to 1 switch return from 2nd switch 2 cores between switches
or
have i just lost the plot

2 plate because no perm feed at light, feed in at 1 switch 2 strappers beetween switches and switch wire up from other switch

is this in conduit sorry mark question was for the op

Agree with Mark,

2 plate - circuits at the switches
3 plate - loop in at the rose

 

[Mr Mark Sparks]

yes singles in pipe, it also could de done with doub ins singles & cpc and t&e for strappers but i dont see why youd bother i just use 3c&E method

could be a pull through

Guys
an old hand here. My understanding of a three plate wiring system was the old junction box method of wiring where you saw only the switch wire and neutral plus cpc at the rose. Four plate tends to be the norm now ie loop in wiring feed and neutral to each fitting in turn with addition of feed and switch wire. It has nothing to do with one or two way switching which still seems to cause a lot of confusion. I have found a great schematic which will help anyone to understand converting single pole sw to two way . Hope this helps
