1)Note thetwo ways to end the splice. When the splice is taped, theends must be bent back so the sharp edges will notpenetrate the tape.

2)When a solderlessconnector is used instead of tape, the ends are cut off

3)When more than two wires are joined in a pigtailsplice, they should be twistedtogether securely before the solderless connector is put.

Multiple-wire pigtail splice

4) Twisting the wires together first ensures that all thewires are fastened together properly.

Western Union Splice

5)The Western Union splice is used whenthe connection must be strong enough to support longlengths of heavy, wire. In the past this splice was usedto repair telegraph wires. If the splice is to be taped,care shouldbetaken to eliminate any sharp edges fromthe wire ends.

T-tap

6)A type of splice that allowsa connection to be made without cutting the main line.This connection is one of the most difficult to make. Acertain amount of practice may be necessary to makethis connection look neat.

Portable Cord Splices

7)Cord splices are weak because there is no connectorto hold them together; therefore. they should be used foremergency purposes only. If the cord must be saved, usetwist lock plugs and receptacles to rejoin the cord.The individualsplices are staggered to prevent a large bump when thecord is taped. Additional strength may be added to thissplice by soldering each individual splice.

Soldering Splices

CC.1.2.11-12.J Acquire and use accurately general academic and domain-specific words and phrases, sufficient for reading, writing, speaking, and listening at the college and career readiness level; demonstrate independence in gathering vocabulary knowledge when considering a word or phrase important to comprehension or expression

1. Because solderless connectors (such as plastic end caps) are time-saving and easy to use, the electrician no longer needs to solder each and every splice. It not only takes less time tomake asolderlessconnection butalso requires less skill. However, soldering is still the most reliable method of joining pieces of wire, and every electrician should learn how to solder.

1. Once the decision is made to solder an electrical splice and the insulation has been stripped off the wire, the splice should be soldered as soon as possible. The longer the splice is exposed to dirt and air, the more oxidation will occur thus lessening the chance of a good solder joint.

1. Clean metal surfaces, free from oil, dirt, and rust (oxidation) are necessary to allow the melted solder to flow freely around the splice.

1. The surfaces may be cleaned by using light sandpaper or an emery cloth or by applying flux to the joint asit is heated.

1. Solder usually comes in either bar or wire form and is melted with heat from soldering devices, such as a soldering iron, soldering gun or propane torch. The electric soldering iron and soldering gun are used when electrical service is available. The propane torch is used to solder large wires or when there is no electricity at the jobsite.

1. Whatever method you use, be sure to apply solder on the side of the splice opposite the point where you apply the heat.

1. The melting solder will flow toward the source of heat. Thus, if the top of the wire is hot enough to melt the solder, the bottom of the wire closest to the heat source will draw the solder down through all the wires.

1. Allow the splice to cool naturally without moving it. Do not blow on the joint or dip it in water to cool it. Rapid cooling will take all the strength out of a solder joint.

1. Once it is cooled, clean off any excess flux with a damp rag, then dry and tape it.

WARNING

Avoid breathing the fumes and smoke from hot solder. Some solder contains lead which if inhaled or ingested can cause lead poisoning. Avoid prolonged skin contact with fluxes. Your supervisor will give you a Material Safety Data Sheet (MSDS) with the precautions for solder and flux.

Taping Splices

Taping is required to protect thesplice from oxidation (formation of rust) and to insulate against electrical shock. Taping should provide at least as much insulation and mechanical protection for the splice as the original covering. Although one wrap of plastic (vinyl) tape will provide insulation protection up to 600 volts, several wraps may be necessary to provide good mechanical protection. When plastic tape is used, it should be stretched as it is applied. Stretching will secure the tape more firmly.

ELECTRICAL SAFETY

Safety for theelectrician today isfarmore complicated than it was 20 years ago. But with proper use of today’s safeguards and safety practices, working on electrical equipment can be safe. Electricity must be respected. With common senseand safework practices, you can accomplish electrical work safely.
