Hi. I purchased a IotaWatt recently for my house. Due to space restrictions, it’s much simpler for me to fit everything near my breaker box using Jack plugs with 90º angles. Also since I’ve seen solid cores are more accurate, i decided to make my own. From this thread:
I followed @overeasy’s recommendation and got the HWCT-004.
Then I investigated the best way and best cable to connect them and got some shielded cable with a twisted pair inside, following the recommendations here:
Quoting from the last link “Decide at which end of the cable you have a good earth connection. You must connect the cable screen to earth at one end only. If you have a choice, connect the earth at the emonTx/emonPi end. If you do not have an earth connection, then you may connect to the emonTx/emonPi’s GND.”
I’m assuming the same thing is valid for the IotaWatt right? It would be much simpler for me to connect to the ground. Can I do this with IotaWatt… Is the ring of the jack connected to ground? Can I connect it to the ground some other way? Or I have to connect all 14 jacks to the IotaWatt and then connect all the shielding together to the house earth wire? Is there any advantage in connecting to the house earth instead of the ground?
Thanks in advance for any help on this topic.
