I am looking to get started with Energy Monitoring in my home and I’ve been reading all the documentation but I’ve hit a bit of a block.
I have two issues I’m hoping someone can help with; supported/recommended CTs and where to get them.
I have a couple of split-core CTs for purely sizing purposes and I have consulted with my electrician who has stated that we are going to struggle to get these into the consumer-unit (the standard UK consumer unit is not very big). We have talked about a double-length/height unit but these are expensive and obviously a significant cost to install (including a full part-P check once installed).
Having been reading the documentation (both IotaWatt and others), i wonder if I would be able to fit solid-core CTs into the existing unit as they look a lot smaller, however I notice that these are not available in the store and I am struggling to find anywhere that sells these with the jack-plugs required to fit to the IotaWatt system. The USB power supply and voltage reference transformer should not be an issue.
Is there anyone here from the UK that has managed to set this up and if so, how did you fit the CTs into the consumer unit (and which ones did you use).
I need to double-check what rating CTs I require (I assume I need 1 for each individual ring main - 12 - and 2 to cover the main cables coming into the unit); I can post a photo on the inside of the consumer unit if it helps.
I appreciate that this is a bit vague, so I appreciate any advice.
Finally, I appreciate that stock has recently been an issue, but will the individual units still be sold in the future? I can only see bundles at the moment.
