I would just like to ask if my wirings for a power control box is correct. I am planning to power 4 independent outlets to actuate pumps and other devices on mains, and control these independent outlets using a 5v relay for an automation project. With that, by what I understand I should wire the four outlets in parallel to independently switch the four AC channels. Here is my wiring so far
I've split the power cable to take the live wire to connect it to the NO port of the relay (most right), and share the power to the other three as shown in the connection. From there, I'll connect the individual COM ports to a respective outlet on its Live connection. I would just like to confirm if the neutral (blue) wire is supposedly as shown?
By what I understand, the GND lines should connect as such to share current return paths, but as for the neutral I am not entirely sure but I do understand it works similar to GND as well for providing current return path. Moreover, I also plan adding a fuse or some type of breaker in the future to provide extra safety for the circuit. As for now, I am connecting the plug to an OMNI extension outlet which provide safety switches and built-in breaker as well.
The relay is opto-isolated, working for 250VAC 10A max rating, where in our country, 220V 10A is provided off mains. Similar max ratings with the outlet.
Thank you very much for any response in advance.
