Hi
Guys how can you connect this type of CT clamp type sensor 250A input 5A output to a arduino for we are concered of the current that arduino will take... btw we doing a 3 phase enetgy meter project. Thank you for replying.. <3

Something like this ?
This example produces a voltage proportional to the input current. It looks like the voltage goes up to 11 volts at 120 Amps (into 1K) input current so you'll need a potential divider to match. The resolution at low currents will be poor.
Are you trying to use the Arduino to measure the current, or are you trying to measure the current the Arduino takes? I guess it's the first for the tool suggested, but you write the second.
