Hello Everyone.
A new member here & while searching for something else I spotted this thread.
I use these crimp splice connectors on my layout.
For main bus wires I use 32/0.2 cable so I use the blue crimp in the center here http://www.rapidonline.com/Cables-Connectors/Crimp-Blade-Splice-33-0190
For dropper wire I use 16/0.2 cable so i use the red spade connectors here http://www.rapidonline.com/FFSearchResults.aspx?qFS=&query=330665&x=0&y=0
You can put on the blue crimps with a good pliers but you need a crimping tool for the spades. I have never had a problem with these connectors provided you use them properly.
There is a company Cooney Electronics in Dublin who bring stuff in from Rapid on a weekly basis. I got all my cable & connectors from them & they are very good. No connection with them other that a happy customer.
If anyone wants any further info just drop me a pm.
