How to Make Electrical Splices

Introduction to Electrical Splices

• The video introduces the concept of electrical splices, defined as the connection between conductors (wires or cables) used for extending or branching lines in various electrical installations.

• Different types of splices are discussed based on specific needs, emphasizing the importance of understanding these variations.

Tools Required for Making Splices

• Essential tools mentioned include:

• Electrician's knife for stripping insulation.

• Diagonal cutting pliers and universal pliers for handling wires.

• A rule or measuring tape to ensure accurate lengths of wire.

First Type of Splice: Rat Tail or Braided Splice

• The process begins with cutting two pieces of conductor wire, each measuring 12 centimeters using diagonal cutting pliers.

• Insulation is stripped from both ends of the wires, approximately five centimeters, allowing access to the conductive material inside.

• The exposed ends are twisted together using pointy pliers to create a secure connection. This twisting is crucial for ensuring a solid splice that prevents overheating and poor installation quality.

Finalizing the Rat Tail Splice

• After twisting, the splice is further secured by compressing it with universal pliers.

• The ends are trimmed with diagonal cutting pliers to achieve a neat finish. Properly executed splicing is vital as loose connections can lead to overheating issues.

Second Type of Splice: Simple Union Joint

• Similar procedures apply; two pieces of conductor wire are cut at 12 centimeters each.

• Approximately four to five centimeters of insulation is removed from the center section before aligning and wrapping one conductor around another securely.

Ensuring Quality in Simple Union Joint

• It’s emphasized that proper touching (compression and securing connections tightly together) ensures high-quality installations.

• The completed simple union joint should be visually inspected for neatness and security.

How to Make a Western Union Splice

Initial Steps in the Splicing Process

• The process begins with calculating how much insulation can be removed from the conductor splice. Approximately six centimeters of insulation is stripped from one piece of conductor.

• After removing the insulation, the individual strands of wire are separated to ensure an aesthetically pleasing splice. This separation is crucial for a neat connection.

• The splicing technique involves wrapping one conductor around another, ensuring that it is secure and properly aligned. A safety knot is also tied during this step for added security.

Ensuring Quality in the Splice

• It’s important to keep the wires organized and not overlapping, which contributes to a more professional appearance of the splice.

• The splice should be tightly wound; using pliers helps achieve a firm grip on the connection, ensuring durability and reliability.

Preparing for Western Union Splice

• For creating a Western Union splice, two pieces of conductor are cut to 12 centimeters each. This length is essential for effective splicing.

• Insulation is stripped from both ends of these conductors by approximately 7 to 8 centimeters using electrician's knife, preparing them for connection.

Aligning Conductors for Splicing

• After stripping insulation, care must be taken not to separate all strands completely; some should remain connected at one end while others are aligned neatly.

• Proper alignment ensures that both conductors match in length and positioning before they are twisted together.

Finalizing the Western Union Splice

• The twisting process involves alternating directions between conductors to create a strong bond. Each strand must be wrapped securely around its counterpart.

• Any excess wire should be trimmed off after completing the twist, ensuring that no sharp edges remain that could cause issues later on.
