AC Safety Quick Disconnect between Inverter and Solar Meter wiring
I have an AC disconnect between the AC output of the Inverter and the Solar Meter installed by APS. That solar Meter then feeds two breakers in my main box. This is a new install and getting approved by APS
Today, the APS guy came out and did a continuity check from the top lugs of the AC Safety Disconnect to the bottom lugs of the Solar Meter. He said, those shouldn't have continuity. I said, the output of the Inverter (AC) goes to the bottom lugs on the disconnect and the top lugs of the disconnect go to the meter. Of course you will have continuity between the top lugs of the disconnect and the bottom lugs of the meter, that's the point. THe circuit, between the inverter and the meter however is broken.
I took my continuity checker and showed the output of the Inverter does not have continuity with the Solar Meter when the switch is in the OFF position, the circuit isn't closed.
The APS guy again said, the top lugs of the disconnect should not have continuity with the bottom lugs of the meter. I then said, well, if I swap the wires in the disconnect, the the top lugs of the disconnect will then go to the inverter and the bottom lugs of the disconnect go to the Solar Meter and then the bottom lugs would have continuity so what the hell is the difference if continuity is between the top or bottom lugs as long as the circuit between the inverter and the Solar Meter is broken when the disconnect is in the off position?
The ONLY think I can see is that the top of the disconnect is labeled "LINE" and the bottom of the disconnect is labeled "LOAD" I've read quite a bit that LOAD should go to inverter, however, the APS guy said LOAD should go to the Solar Meter.
As far as a circuit is concerned as long as the lugs at the top and bottom of the switch are disconnected, the circuit is broken. But, the top lugs of the disconnect are marked "LINE" so I would think their thought is LINE should be INVERTER and not the Meter. The circuit doesn't care, but, it's more of a semantics thing.
So, I said, if I swap the wires in the Disconnect so the top lugs of the disconnect go to the inverter and the bottom lugs of the disconnect go to the Solar Meter, then everything is ok. He said "Yes".
Ok, I'm so frustrated, what the F*!* difference does it make on a quick disconnect as long as the circuit is broken? IF I painted over those little "LINE" and "LOAD" stamps on the metal box, nothing changes. I just don't get it.
