This person did not have a 32A single-pole circuit breaker, so he decided to connect the circuit to a 16A bipolar circuit breaker. First, the person assembled it using only one pole of the circuit breaker, that is, he connected the 4.0mm2 cable to one pole of the 16A bipolar circuit breaker. This person realized that when turning on the circuit breaker it would not trip (the 28A current was much greater than the current capacity of the 16A bipolar circuit breaker), so the person remembered that the electric current divides and decided to branch the cable and connect a cable to each pole of the circuit breaker. The new connection to the 16A bipolar circuit breaker was then made by dividing the 4.0mm2 cable into 2 cables, thus connecting a cable to each pole of the bipolar circuit breaker. For this new connection that was made, the following questions remain: A) Will the electric current divide? B) Will the circuit breaker work normally and not trip? C) Does the NBR-5410 standard allow this type of connection? Participate, leave your comment below. 👇 👇 👇 We will give the answers to these questions in the next video 🎥 that will air on 12/19/2018.
