The document discusses various types of solderless electrical connections including terminals, splices, forks, spades, eyes, and butt splices. It provides instructions for properly installing different solderless connectors using the correct tools to strip and prepare the wires and crimp the connectors to make dependable connections without solder. The document also reviews different solderless connection methods and tools.

1. Solderless Connections

2. Solderless connections join electrical
components without solder.

3. A great variety of terminals are
available, these are noninsulated

6. Butt Splices

7. Forks & Eyes

8. Spades

9. Wire Nuts

10. Dependable connections can be
made without solder.

11. Making good solderless
connections.
1. Determine correct connector
2. Select correct tool
3. Prepare wire
4. Set connector into crimper
5. Insert wire into connector
6. Crimp fully
7. Crimp strain relief if required
8. Install finished connection

12. Selecting the correct connector
Use the one that best matches demands of the installation.

13. Select the correct tool
The right strippers and crimpers are essential for good connections.

14. These are NOT crimpers !

15. Prepare the wire
Select right stripper size and strip insulation
without cutting wire strands.

16. Set connector into crimpers

17. Setting connector into crimper

18. INSTERT wire into connector

19. Fully crimp connector

20. Crimp a strain relief if available

21. Crimping step 1
Crimp the conductors for a secure
electrical connection.

22. Crimping step 2
Crimp the insulation for a
Strain Relief.

23. INSTALL the connector

24. SECURE installation

25. Splicing

26. Select correct size of splice.

27. Strips wire(s) to be spliced

28. Insert wire into only one end first

29. Fully insert & crimp splice
at one end first

30. Insert & Crimp other end

31. Finished Splice

32. Two types of crimps

33. Different types of crimpers can
do the same job.

34. Different jaws to crimp with

35. Two types of crimping action

36. Second type of crimping action

37. Butt splice crimped two ways

38. Wire Nuts
Common wire connections in industrial
and commercial wiring.

39. Steel threads inside a
plastic shell.

40. Inside, coned threads twist and
hold wires together.

41. FOUR steps for wire nuts
1. STRIP
2. INSERT
3. TWIST
4. TUG

42. Strip two or three wires that are
to be connected.

43. Insert wires into wire nut

44. Twist nut until wires are tight.

45. Tug on wires to make sure
connection is secure.

46. Securing wires
It is important to secure wiring for safety and dependability.

47. Wire bundle mount

48. Wire bundle clamps

49. Cable Tie Wraps
Cable tie wraps are used in many different ways to secure wiring.
