Thinking about it - as a temporary solution - this might be possible.I don't think you'll find one !
'Hall Effect' sensors measure current in a single conductor; Twin&Earth cable is three separate conductors in an outer sheath. To get a reading, you'd need to strip off the outer sheath then clip the sensor round just one of the conductors - pref the one coloured brown (or red if it's an old cable).
A smaller/simplified version of that would be ideal. I just need to monitor/total up the consumption of a single spur socket. And only for about 1-2 months.Why not get one of these Efergy things, and open your consumer unit and clip it round the red/brown wire going to your cable.

Just looked this up. They're pretty cheap from ebay and actually I think these would be better for what I am thinking. Thanks a lot!Probably an Emlite meter is the best and cheapest way to do this but it's not a clamp on meter, will need to be wired inline, needs some protection etc etc
Thinking further, your suggested item looks like a good idea. Is there a kit available so I can measure/monitor many circuits from inside the consumer unit? Also, what about a secondary consumer unit?I don't think it will be useless even after the month, will it? I've had one installed for years measuring how much my storage heaters take overnight. I think an enquiring mind will always find a use for it.
The bit that goes in the consumer unit is very small.
I believe you can get extra pick up coils and plug them into the Efergy.Thinking further, your suggested item looks like a good idea. Is there a kit available so I can measure/monitor many circuits from inside the consumer unit? Also, what about a secondary consumer unit?
Got it setup - it's a much better online software platform than the previous Energenie Mihome kit that I was using.Thanks. I've ordered a kit off ebay to trial this. Might get messy in my consumer unit, but it's setup and forget then that's fine.
Thanks - nice idea. I'd rather find a deal on the proper CT sensors for the Efergy and use that. It's quality controlled then incl. any calibration/testing.Presumably if you know what you're doing you could even install a loop of similar gauge wire outside the consumer unit, and connect with a choc block?
Oh I didn't mean that in place of the sensor. Just to save keep opening the Consumer Unit, you could have some labelled loops sticking out of the top to clip your sensor(s) to.Thanks - nice idea.
