Since we're on the subject, is there a good reason why the CT should be put around the live feed from the main meter to the consumer unit, rather than the incoming live to the meter? It only fits around the latter...
I don't see a technical problem and I think the advice with the meters comes from supply companies being rather twitchy about anything at all being messed with on the inbound power to the meter for obvious reasons.
Now a passive device it may be...but I think the instructions just go for the cautious approach as what is connected after the Meter and Supplier fuse is your business where as those devices and the cable attached to them belong to the supply network.
It's the same reason why they say you should seek approval before attaching the "magic eye" to the meters for the optical reading type of installation...they aren't your meters.
