Generally current transformers should have the ability to be shorted in order to perform maintenance. Disconnecting a current transformer while it is installed on a current carrying conductor can result in damage, although at residential current levels this is not as likely.
Often shorting terminal strips are used but on a whim I've decided to make my own shorting terminal block tailored for my N20.
Components are almost all on hand.
Waiting for a DIN rail mounted pcb holder to arrive.
Once that shows up I'll confirm measurements and send the circuit board design for fabrication.
