The Britannia splice is a connection between large solid wires. Then secure one wire firmly and begin the wrap motion of the opposite wire until one turn is completed. They may crack or break, or edges may be nicked by such abuse. The insulation that we remove should typically expose three to five wire diameters of the stranded wire. To make the Western Union splice, first remove about five inches of insulation from both wires and cross the exposed wires.
Both wires must twist for the joint to be tight. Carefully twist the wires so that they remain in line with the rest of the wires, rather than bending up at an angle at the twist joint. Hold the tool firmly shut while pulling it down the length of the wire. It is suitable for service where there is no mechanical stress when wires are to be connected in an outlet box, switch, or conduit fitting Y-Splice This method of wrapping is generally used on small cables because the strands are flexible and all can be wrapped in one operation. Find the right long-nose pliers.
Needle nose pliers can be damaged by using the tips to bend too large a wire. However, a specially designed tool to avoid nicks is called automatic wire stripper. This will strip the coating from the wire. The braiding is cut back to a distance of about 6 inches, and a shoulder is neatly formed with asharp knife. If the cuts are too wide apart, the wire may not be long enough to make the required connection. Ensure that the inner opening is big enough to allow the metal conductor inside the insulation to pass through the cutting operation without being damaged.
The Western Union splice is created by removing 5 inches of the insulation from the ends of the two wires. Crushing the Insulation Crush the insulation on the long conductor at the point where the short one ends, that is, one pliers length from the end of the long conductor. Large strands are rigid and require considerable time in making such a splice. The joint now assumes the appearance shown in the upper part of Fig. To make the join using No. The seizing wire is bent so as to have one-half for wrapping to the left and one-half for wrapping to the right.
The branch wire is laid behind the main wire. A wide variety of electrical wire joints and splices options are available to you, such as crimp terminal, splice. The most common form of the splice joint is the half lap splice, which is common in building construction, where it is used to join shorter lengths of timber into longer beams. The branch wire is brought under the main wire, around itself. Use a larger pair of pliers or a bolt cutter. The free ends are then forced through the grooves from one ends to the other end of the other of the large single conductors.
Western Union Long-tie Splice This is used extensively for outside wiring to extend the length of wire from one end to another. There are two directions to twist, you do not want to twist the entire wire, just the splice. Get into small areas with long-nose pliers. Solder the joint together and wrap tape around it. And whether electrical wire joints and splices is pvc, or pe. The wire should be stripped to allow a minimum of three wraps — not twists — of each wire around each other.
The main cable is placed into this V-shaped space and forced down to within 1 inch from the insulation of the tap conductor. Push it up the wire out of the way of the splice so that it is not prematurely heated by the splicing operation. Further solidification comes through soldering wires. This may draw the temper and ruin the tool. A rat-tail joint, on the other hand, is commonly used to connect wires in a conduit or junction box. Equipment Used: Long Nose Plier and Cutter How to Use: 1. A standard wire stripping tool will have multiple stripping openings.
If the wire is a solid conductor wire, this will not be necessary. The easy twist will facilitate tap wire movement. Grasp the intersection with the pliers and turn both wires simultaneously. The best ends are then cut off close to the joint. The difference is that a number of long twist are made before wrapping the end turns. Finally, we solder the connection. The strands are next divided in half by forcing the screw driver through the center of the bared portion of the main wire.
Each conductor must be spliced and taped. Pliers should not be used for cutting hardened wire unless specifically manufactured for this purpose. The common types of wire splices are the Western Union splice, tap splice, staggered splice, fixture splice and rat-tail joint splice. The wires are first stripped and then pre-tinned in the same manner as the wrap splice. The center of the wrapping wire is then brought to the center of the conductor, one half of which is wrapped in one direction and other remaining half in the other as far as the best portion. Strip your wire to about the same length on both ends 2cm.
