The problem is that it is not possible to make an electrical installation without joints. Therefore, we need to take every care to always ensure a good connection. And this is so true that even NBR 5410 states in its item 6.2.11.1.11 that splices are only allowed in junction boxes. So, don't make splices in cables and "hide" them inside the ducts, okay? That's wrong. Basically, there are two most common and popular types of splices: Derivation splices and Extension splices. Derivation splices are made when the intention is to create power supply branches from an existing network. For example, branching one outlet to another. Extension splices consist of increasing the length of the conductors. Over time, splices have undergone updates in their form of execution. Previously, the most common splices were those that required the use of insulating tape to insulate them. Currently, there are several types of connectors available on the market that facilitate the connection between cables. But André, is it wrong to use insulating tape?" No, my dear, on the contrary, a well-made and correctly insulated splices are quite viable! However, considering professional use and the need for agility, the service is neither practical nor quick, and depending on the quality of the tape you use, it is also not safe. Let's start these derivations in Bedroom 2. The cables that run through the section marked L arrive at the ceiling box in this room. Consulting our table with wiring legends, we see that the phase and neutral cables of lighting circuit 1 and phase, neutral and ground of circuit 4 of the bedroom's sockets pass through this section. All of these cables are arriving at this ceiling box here. Let's start by derivating the cables from the socket circuit. They will be derived to these two conduits, since we have a socket point here on this wall and another 3 socket points on this wall. Here in the ceiling box, we will use the 3-way WAGO connector. Let's start with the phase cable, which is the one in red. See how simple it is: First, we strip the ends of the cables by about 1 centimeter. Then, we lift the small orange lever on the connector. Now we're going to take the cable that comes from the panel and insert it into one of the connector's paths, then lower the lever. Next, we're going to take the cable that goes to the other side and insert it into the second path of the connector, and finally, we're going to take the cable that goes through the other section and insert it into the third path of the connector. That's it! The phase cable for circuit 4 of the bedroom's sockets is done. Now we're going to repeat the same process with the neutral (blue) and ground (green) cables from this same circuit. The phase cable from circuit 1 is going straight through and down to the switch, the neutral cable is waiting here for when the light fixture is installed. After making the branches in the ceiling boxes, we're now going to branch the cables into the junction box on the wall where there will be 3 socket points. Note that from this box here, we're going to branch to two other boxes. But at this point here we have to be careful, because this point will also have a socket, so we need to leave a waiting line of cables here too. So, let's make our splice in this box here. And this time we're going to make the splice using insulating tape. Again, we will start with the phase cable. We will strip the ends of the cables to about 7 centimeters. We will start by taking the cable that comes from the ceiling box and joining it with the cable that goes to the socket on the right and with the cable that goes to the socket on the left. Now we will join a pigtail of about 20 centimeters to these cables, which will be the cable to power the socket that will be at this point. After joining all these cables, just take the insulating tape and pass it over the joints. It is important to start just before the beginning of the joint and pass a part over the previous layer.
