Having at the moment to fit lots of replacement sockets for a client who has supplied these crabtrree sockets
The terminal entries are shallow but two staged,in that where 3 cores are involved one or two may seat ok and the 3rd will probably be loose or pop out
The terminal fixing screw is more akin to a switch size screw and the terminals for live and neutral are set so central and low down at the socket that dressing and keeping the connections intact and reliable is far from what I am happy with
I have yet to fit one of these sockets and been totally contended with the effort
When I make a connection to anything electrical I would never doubt its reliability
These sockets make that feeling of reliability dis apear and thats a first for me
I will repeat what I stated before
Under no circumstances would I fit them on a job that I supplied or advised on
Fitting one of them and then fitting even a volex is a different experience
I used to have high regard for crabtree fittings but they have made me doubt their commitment to anything aproaching quality with those contraptions
Thats a negative for crabtree from me then
