No. It's always required.
I'd be grateful if you'd humour me and probably fill a gap in my knowledge.
I don't do many of these, I always follow the flow chart. I always fit CT clamps and set a grid limit.
But I have to admit I don't actually know why a CT clamp is automatically required if you have an 100 amp service fuse, you apply to connect, and your judgement of maximum demand (including the charger) is significantly less than 100 amps. So I went researching.
It seems that part of the answer lies with the requirements of the Electric Vehicles (Smart Charge Points) Regulations 2021, which set out what any charge point sold must be able to do. Without going in to chapter and verse, internet connectivity and a CT clamp would be needed for some of the requirements, so for me to re-sell this to a customer it would need to comply.
All fine, however I'm still confused, as the emphasis of legislation seems to be what on what the product must be capable of doing. I haven't yet found anything statutory saying that anyone fitting an EVCP MUST connect it to the internet and install the CT clamp. (It's obviously a good idea and I do it!)
Is it as simple as it being a very good idea to follow the manufacturers installation instructions?
