I have a problem with the installation, it turns out that when I connect several devices, the voltage and the power drop ... I wonder if it is the cable since most of the installation is of the number # 12, I suspect this since I realized that At 4 amps the voltage on the line drops to 70 volts ..... look for false contacts, find sulfate in clean terminals and reconnect and even then the problem continues, help!

Hi If the voltage drop is throughout the installation, you should look at the entrance to where the circles branch Applies load and voltage measurement on the main switch. If there the tension is normal, look for the problem inwards, if there the tension is low, look outside, you will have to call the distributor These things can happen for many reasons from fine cables to poor connections. It can even be in the connection of the network or in the neutral of the house Cheers

THANK YOU FOR YOUR COMMENTS, EFFECTIVELY, THE PROBLEM WAS IN THE NEUTRAL OF THE ACCOMMODATION, A BIMETAL CONNECTOR WAS INSTALLED, BECAUSE I ONLY HAD A LOOP BETWEEN THE ALUMINUM CABLE THAT COMES FROM THE TRANSFORMER AND THE COPPER OF THE ACCOMMODATION, GREETINGS!

using 12 gauge cable is the right thing for the outlets, what you should do is see that there are no false contacts before taking the measurement, see if there is an electric shower on that has not been powered from the general key, and also Check if in your area there has been a low voltage of the electric company
