How to make an electrical control for a lighting circuit using a contactor to light a very large space? Do you know how to make a circuit to connect several lighting circuits, for a lighting circuit for a store, warehouse, school, sports court and very large spaces? To make circuits like these, we can use a contactor to power a large number of lights, because the switch does not have enough capacity to support the electrical current of all this lighting, in addition to being dangerous to activate all this load with just a single switch. It is also not safe to use the circuit breaker as a switch, as demonstrated in the video. For this we can use the contactor, but it takes up a lot of space inside the electrical panel, so we have the option of using the bipolar modular contactor, which can interrupt two phases and takes up less space, because it is compact. This way we can divide and control several lighting circuits with a single panel, making the activation safe and efficient. I will leave the electrical projects and diagrams for you to use to make the circuits. COMPLETE ELECTRICIAN INSTALLER COURSE! PRE-LAUNCH: https://eletricidadeonline.com/cursoe...
