Hey guys,

I've come pretty far with designing my setup to measure te power usage in a 3 fase 400V oven.
Only now i have to check if everything is right, and how to put the output signals to the amount of current flowing through the machine.

The parts i use:
- Arduino Giga R1
- ZMCT124I (CT-sensor)https://www.micro-transformer.com/current-transformer-flying-wires-ZMCT124I.html
-AD8418A amplifier https://www.analog.com/en/products/ad8418a.html

My Schematic so far:

A1: Analog Pin 1 Arduino Giga
GND.: Gnd output to Arduino Giga
3.3V: 3.3V input from Arduino Giga

I'm not completly sure about the burden value, but got the advice from an expert that's is the right value.

Let me know what you think and how to program this setup for the Arduino Giga R1

No one is going to write programs for you.
Note that there are current transformer setups more suited to Arduino and possibly already have the necessary libraries and connection/example programs available.
Bit of an overkill with your selection of Arduino model.
