Bill, I visited your welserver site and saw the pictures above but I'm still a little confused on hooking up my wattnode meter to measure my geo system. I want to get my welserver up this coming weekend. I bought the Wattnode meter with the P3 option and I understand the ct's, but the hooking up the power for the device is a little confusing. It says I should choose a 5-20 amp circuit to power, yet in the diagram it shows the ct's on the same wire as the input side which in my case is 2 wire, 70 amp breaker for the Climatemaster WTA heatpump. Do I just need to make sure it's on the same "phase" or should I actually attach it to the 70 amp breaker?

Can you clarify this?

Also I would be interested in your assistance with the welserver computations to use just one of the P3 circuits to measure 240v, as I saw your post on this subject in another thread.... that way I could monitor the well water pump and the circ pumps separately with the other p2, p3 lines. My climatemaster uses 6-2 wire and the grufundos pumps use 14-2 and my well pump uses 12-2 (all 240 volts). Do I understand I can measure (accurately) 3 240v circuits with the P3 option???

Your wisdom and experience is apprecitated!

Mike

Mike, I started a new thread for you so as to not dilute this thread, and to give you the 'freshness' of a new thread.  My comments are in the new thread.

Best regards,

Bill
