I've had times when I've thought aha, clamp meter is spot on and then the same clamp meter used in exactly the same way gives a wildly different reading.
I know of a DC that gives you power readings based on clamp meters... they once said "we need to talk to you as you are pulling 32 amps in cab XXX". It transpired they were using a clamp meter and it was nothing of the sort... around 12 amps. To this day they still use clamp meters for all readings I believe :-S

apologies that's what I meant...It wasn't - it is 0.61 and 000.6 respectively![]()
I've always hated clampers!

If you can access the wires before the go in the outlet, like the j-box or something, you can clamp the "hot" wire.
Already been said above chap![]()
As an aside... for anyone looking to do this in offices or retro fit to your data centre have a chat with MeasureMyEnergy
Run by someone who understands our industry quite acutely!
For those interested we had a custom horizontal PDU designed for us by a local manufacture it has 48 x C13 sockets max input of 32 amp single phase 240v.
Each c13 socket within the PDU is metered with power consumption data stored in flash memory on the PDU which can be accessed via a web interface or API directly.
We poll each socket every 3 seconds and bill the customer in kwh for actual power consumed.
We also monitor each single phase breaker within the distribution board via branch monitoring and breaker monitoring on any 3 phase breaker.
edited.. that would teach me to be on the internet late Friday night... and not re read what i type...
Kindest Regards
