[QUOTE="Andy1733, post: 540145, member: 34898"] This is how I understand a CT Clamp works. I'm sure of I'm wrong someone will be along correct me.. The CT clamp works by reading the current flowing in the direction the arrow is facing. So if the CT clamp is pointing towards the meter and you have the back to grid feed turned off/disabled. You will get the zero figure like you stated in the op. If the arrow on the CT clamp is facing towards the CU and you have used 9kwh of power like octopus have stated, then you should get 9kwh readings from the CT clamp. I read somewhere when I was installing mine that if the live and neutral feed to the meter are reversed (by mistake) this can give the meter a wrong reading. [/QUOTE]
