Imagine the scene: You just moved into a house or apartment that only has 127V outlets, but you need a 220V outlet to be installed. Then, the Wire PICKER arrives and does what? He looks at the QDC, sees that there are two phases arriving and takes the 220v from any place and takes it to the point where you wanted the outlet. But now comes the question... Is it right? Think about the answer while you like us and take the opportunity to subscribe here on the channel too, we teach a lot of things related to the electrical area here, so activate the bell too so you don't miss any content, okay?! So, let's get to the video... Hey, my dears, how's it going? The 4th edition of the Professional Electrician Week is coming up this month. Sign up now using the link in the description, because there are limited spots available to watch the live event. After all, I've prepared some great classes that teach you how to design an electrical installation from scratch and also how to execute the entire project with a great step-by-step guide. Sign up for this event and become a much more confident and confident professional electrician. Just like the Pica Fio hates. But back to the subject of the class, let's see the mistakes that a Pica Fio makes when simply "pulling the 220", let's take it one step at a time: We know that installing the outlet is really simple, but three questions must be asked to ensure there is no room for error: 1st - Does your installation have the available load to serve this new 220V circuit? 2nd - Can the piping handle the cables for this new circuit, or will it be tight? 3rd - Are the QDC loads balanced, in normal operation, are the currents in the phases similar? Note that these are several questions for a simple situation, at first, and that many people ignore, perhaps in a hurry, perhaps because they don't know, or because they lack knowledge", which ends up putting your family's safety at risk. But let's start by answering the first question, about the load available in the property! If your installation cannot support the increase in load to serve a simple 220V circuit, it will most likely overload your installation, which gives us 2 scenarios! 1st - In the best of worlds, it causes the power to go out, then the wire cutter comes and brings the miraculous solution of only increasing the circuit breaker current, claiming that it is weak, but we know that this causes overload in the cables, so don't let anyone do this, people, for the love of God, the circuit breaker must be compatible with the installed cable! 2nd - In the worst case scenario, if there is no circuit breaker for protection, the chance of a fire is high, in which case only God can protect you! So before you just go out and pull the 220V, first analyze the current of the main circuit breaker and the power cables and confirm if the system's capacity supports this expansion. Even if it is a simple socket, in many cases it can greatly affect the distribution, since many installations are old, are already overloaded, and this puts all users at risk. Be careful, okay? The second question you should ask yourself is about the piping where this new 220V circuit will pass. It is quite common for the wire cutter to not respect the occupancy rate of the conduit. As we have already explained in several videos, when there is current flowing through a cable, it naturally heats up, even if it is well dimensioned. Therefore, the more cables we have in a conduit, the hotter that conduit will get. And the hotter it is, the greater the resistance of the cable and vice versa. So my dears, I know that in practice it is very difficult to ask this. I am not just an office engineer, I am a field electrician too. But whenever possible, try to comply with the occupancy rate of the conduits. Roughly speaking, if you see that more than half of the conduit is already full of cables, look for new routes, look for a new path. If there isn't one, then I recommend making a new pipe, embedded, overlapping, be creative, try to solve the problem for the customer, avoiding future problems for you and for them, okay?
