CT Clamp connections inside consumer units

Alan B

I am looking at how best to terminate EV ultra cable for a EV charger at the consumer unit end.

The data cable for EV ultra has insulation rated at the same voltage as the power cables and therefore can be run inside the consumer unit. If there is space it would be quite tidy to actually mount the CT clamp inside the consumer unit as well. 

I have seen some on you tube do this with some heat shrink to give extra protection and wagos to make connection between the EV ultra and the CT clamp cable. I would probably go for a crimp connector as myenergie at least seem to feel spring connectors are unreliable for data.

 

Just wondering if others view this as an acceptable/good solution

    2no Myenergi Zappi units on a 3pn system. I like having the connections in a separate enclosure rather than in the distribution board where they can be upset should access be required for alterations and the like.

    edit; the board on the left is to be replaced shortly. Had the connections to the CTs been made in there then Heaven knows how some sparky may have left them. Even with EV Ultra, I would arrange breakout of the CT connections before entering the final DB.
