ADE7753: Isolaton and CT choose

Hello!

I have two questions for 7753.

 

1. Is the voltage channel isolated from other circuit? If I use a resistive voltage divider, can I safely use external MCU interfaces (USB, RS485 etc.)? Or I have to use some isolation technologies? Or I have to use an isolating voltage transformer on 7753 input?

 

2. Can you recommend right model of current transformer for range of 0.1-50A?

 

Thank you,
