Splice 2 100 watt speakers to 1 wire
Soldering becomes more problematic as wire gauge increases a 14ga. Good soldering irons or soldering guns usually start at about $40. However, soldering requires considerable more skill than crimped or twist nut splices and requires specialized tools, namely an adequate soldering iron. A successfully soldered splice will be as strong as the cable itself. Soldering is probably the most robust method of splicing.Under no circumstance should butt splices or crimped caps ever be used with solid-core wire like Romex, ect. Butt splices if done correctly are about as sturdy as twist-on nuts and crimped caps and require no taping.Ĭrimped devices are designed to be used solely with stranded wire. Like crimped nuts, butt splices should be firmly and fully crimped with a correct-sized crimper jaw, and the connection should be subjected to a pull-test afterwards. In other words, no bare wire should be exposed. The insulation should fully butt up against the internal metal sleeve, and be fully covered by the outer plastic cover. With butt splices, the insulation should be stripped back only far enough for the bare wire the fully seat in the metal sleeve. Like nuts and caps, there are specific sizes of butt splices for specific gauge size: Yellow butts are for 10-12ga. Butt splices are the choice if the spliced wire is to be run around baseboards. Insulated butt splices are installed in-line and as such are the best splicing method where there are concerns for aesthetics.Crimped caps, if done correctly, are about as sturdy as twist-on nuts and require no taping. The cap should be firmly and fully crimped with a correct-sized jaw of a crimping tool, and the connection should be subjected to a pull-test afterwards. Again, there are specific sizes for the gauge of wire you are using, and the insulation on the wire should not be stripped back so far that bare wire extends beyond the base of the nut. Crimped caps or nuts are similar in application and appearance to twist-on wire nuts.The final product is rather bulky and unseemly, and as such wire nuts are best for “out of sight” splices: in-wall, attics, etc.
Indeed, each splice should be given a sharp tug to make sure the connection is secure. If they are done right, wire nuts are reasonably sturdy and can withstand a good amount of pressure or pull on the cable. The insulation on the wire should not be stripped back so far that bare wire extends below the base of the nut. Usually this is an indication that the nut is too large.Ī wire nut splice does not need to be taped if done properly. If the nut never gets tight enough to stop turning, it will not be a secure splice and will easily pull apart. The nut should twist on very tightly, to the point where it will no longer turn. (Please note these are not exacting guidelines: The more individual strands there are in a wire of a given gauge, the thicker it is physically, thus possibly requiring a larger wire nut.)ĭo not twist the wires before they are inserted into the nut – let the action of the nut do that. stranded speaker wire, yellow for 14ga., orange for 16ga., etc. The key to a good twist-nut splice is selecting the correct wire nut size for the gauge of cable you are using.
However they can work well with stranded wire if installed properly, and make for excellent connectivity.
Twist and tape splices in an attic at your own peril. It's the only kind that I've found that won't loosen with time - indoors at least. If you must twist and tape, use only the most expensive 3M electrical tape - usually around $3 a roll at the hardware store. Furthermore, tape tends to loosen over time as the adhesive breaks down, especially cheap electrical tape. A pull on the wire will usually make the splice separate.

Therefore if there is ever a problem in the future where that cable is involved, the splice point is the first thing to check.Īs far as how to accomplish the splice there are several methods, all with their own specific strength and weaknesses: The only problem with splicing is that (obviously) the structural integrity of a cable is compromised.
