Double back & Twisting wires - Best Practice
Posted: Thu Dec 08, 2022 9:07 am
What is the current best practice when it comes to terminating wires, I'll break it down a bit.
- 1 x wire into round terminal with screw
- 1 x wire into clamp terminal (MCB, Iconic sockets etc)
- 2+ x wire into round terminal with screw
- 2+ x wire into clamp terminal (MCB, Iconic sockets etc)
What I've been doing:
- 1x wire into round terminal with screw.
1mm always double back, multi-strand twist strands up tight & double back up to 2.5mm if it will fit. Always twist up multi-strand wires tight.
- 1x wire into clamp terminal (MCB, Iconic sockets etc)
same as above (although I've heard its best not to twist the strands up tight)
- 2+ x wire into round terminal with screw.
Twist wires together only.
- 2+ x wire into clamp terminal (MCB, Iconic sockets etc)
same as above (although I've heard its best no to twist and just have cables next to each other)
I've heard twisting up strands tight is bad practice as the copper work hardens and can become brittle. Also twisting multiple wires together makes it difficult to add another wire in the future or separate if needed.
Thoughts?
