Section to more than 75 percent of the cross-sectional area Splices, and taps shall not fill the wiring space at any cross Space at any cross section to more than 40 percent of theĬross-sectional area of the space, and the conductors, Or overcurrent devices, unless adequate space for this purpose Used as junction boxes, auxiliary gutters, or raceways forĬonductors feeding through or tapping off to other switches **Enclosures for switches or overcurrent devices shall not be ** 312.8 Enclosures for Switches or Overcurrent Devices.

Wrap each bare wire around the other at least three times. Cross the bare strands about a third of the way up. Instructions: Strip one to two inches of insulation from both wires. It is my opinion that most enclosures of this nature have specific space in the top and bottom and sides for splices and clearance…some will disagree but I happen to believe it is so. Also referred to as a Wedding Splice, this method provides many points of contact between the individual strands. Many times (2) 200A panels will be fed from a 400A meter enclosure…so what you have is (6) 2/0 CU conductors coming into the first one and (3) will continue through to the second 200A panel…( notice I did not downsize my neutral…I like full sized neutrals when at all possible these days )īut the panel is clearly a allowable raceway…now their are some limitations to this…and circuits of other systems not using the panels as raceways…but they are considered raceways in the above mentioned reference. Keep practicing your soldering technique until you are comfortable with it before you attempt it in the most confined spaces of a motorcycle.A Panel is very MUCH considered a raceway as most in my opinion have adequate space for these conductors and spliced also in as much you can clearly pass SE conductors through it, splice in it if needed and so on as long as you meet the requirements for it. ![]() Then wrap it with electrical tape or shrink-wrap to prevent any accidental grounding against other wires or connectors. It looks ugly and will make the splice much larger once it’s covered with tape.Īfter the splice has cooled, trim any loose wires that could poke through the tape or shrink wrap. While you want the solder to cover most of the splice, try to avoid leaving big globs of solder on the joint. Touch the iron and solder to a few points on the splice to make sure it is uniformly spread throughout the wire strands. Capillary action plays an important role in distributing the solder throughout the splice. Holding the iron below the wires allows the heat to travel upwards while gravity pulls the molten solder down. Instead, allow the iron to heat the wire to the point that it melts the solder. When melting the solder to the wires, try not to touch the iron with the solder. This helps to spread out the heat when the tip touches the wires.

Anyone, even someone whose hands shake as much as mine do, can learn to solder with a minimum expenditure of blood and treasure. The source of the splicing fear usually is ignorance about soldering, which apparently many feel should only be done at midnight, during the full moon by a practitioner of the dark arts. Never fear, it is perfectly acceptable to splice wires if done correctly. However, soldering is also a great source of distress amongst novices. Soldering uses a hot iron to heat the wires to a temperature that will melt the solder, which when it cools takes care of the sturdy physical connection and the electrical conductivity. Mechanical connectors which physically clamp the wires together or to a common conductor are the easiest, but they take up more room and particular kinds are prone to failure. This can be done a couple of different ways. Wire splicing is the process of physically connecting two or more wires to make a mechanically strong, electrically sound path. While cutting your motorcycle’s wiring harness is not to be taken lightly and should only be attempted when you are certain as to which wires should be cut – by, say, obtaining the factory service manual – the process isn’t really that scary. Upon a little digging, the bugaboo is usually fear of splicing wires into the bike’s harness. Time and again, I’ve had people tell me that they are afraid to modify their bike’s wiring harness to install a new accessory. ![]()
