00:00These are tricks electricians don't tell you, especially the last one.
00:031. First, wrap the wire three times around a steel nail.
00:06Then cut the wire and bend the end, leaving it doubled.
00:09Place it along the side of the lighter and secure it tightly with electrical tape.
00:13This turns it into a soldering iron, making it very practical for soldering at home.
00:162. Connecting a flexible wire directly to the terminal can cause it to come loose easily.
00:21You can turn it around instead.
00:23First, tighten the inner clamp.
00:24Then fold the wire back and tighten the outer clamp.
00:26Fold it over and secured twice, the wire stays firmly in place.
00:303. Using the same wire in this multi-terminal connector can leave the connection loose and prone to poor contact.
00:36After stripping the wire, separate a few strands and wrap them around the remaining strands.
00:40This way, the force is no longer spread out and instead acts on the entire bundle.
00:44This prevents poor contact and makes it harder for the wire to come loose.
00:484. Securing the copper wire directly under the washer can leave it loose.
00:51First, bend the wire with needle-nose pliers so that it curves around the screw.
00:55But don't shape it like an S. The ideal shape is a C.
00:58An S shape may look perfect, but the contact can overheat and cause a short circuit.
01:035. In tight spaces, the roll of tape cannot rotate around the wire.
01:07Take a wooden stick and wrap electrical tape around it to create a small roll.
01:11With this smaller roll, working in tight spaces becomes much easier.
01:156. When fitting a crimped terminal onto flexible wire, the strands often spread apart.
01:20Before starting, mark the terminal length on the insulation and strip the wire.
01:247. Slightly farther down, make a circular cut in the insulation with a utility knife and push that piece toward
01:30the opening, gathering the loose strands together.
01:32When you insert the terminal, it pushes the insulation downward and keeps the strands together as they enter.
01:377. When making a branch connection on the main cable, the cable size makes it difficult to secure the branch
01:43wire firmly.
01:43Strip a longer section using a utility knife.
01:46Then wrap it twice around the main cable and make this cow hitch style knot.
01:49Once formed, the harder you pull, the tighter it becomes.
01:53Finally, wrap the remaining end around a few more times.
01:55This connection provides a larger contact area, conducts steadily, and does not come loose.
02:008. Directly joining two cables of the same diameter often leaves the connection unstable.
02:04First, use a saw to make a diagonal cut in the cable.
02:07Then finish the cut with a grinder.
02:09Make the same bevel on the other cable and join the two using a compression sleeve.
02:13This increases the contact area and also strengthens the connection.
02:169. How does an advanced electrician join these seven-strand cables?
02:20Interlocking them like this, or placing the ends parallel and simply twisting them together, may make the outside look very
02:25tight.
02:26But on the inside, several strands may not even touch each other.
02:29This causes the current to be distributed unevenly.
02:31It may seem practical, but it creates risks in circuits carrying higher current.
02:35Look at the standard interweaving method for seven-strand cables.
02:38Strip about 10 centimeters from each end.
02:40Cross the exposed copper sections.
02:42Wrap the top three strands around the upper section of the other cable.
02:45Wrap the remaining four strands around the lower section, forming a braided knot.
02:48Then symmetrically wrap the seven strands from the other cable.
02:51This allows the current to flow continuously across a larger area, reducing contact resistance.
02:56And it also looks perfect.
02:57Ideal for perfectionist electricians.
02:59That means that the most important is that the other cables have to scrape the same lines.
02:59But no oneís have to pull them realistically across the same lines but this means obviously
02:59that they build up the other cable with just the same lines to take them at the same lines at
02:59the same lines at analogue.
02:59Only one of course of the other好的 cable has to be Aer Arkham.ія
