G99-SGI-3 4.4 kw set export limit phase to neutral loop impedance test on site

[DPG]

so as i thought 0.309 ohms read from loop tester = 309 m ohms phase to neutral loop impedance and 0.471 ohms = 471 m ohms phase to earth loop impedance

Yes, but 180m is not 0.018 Ohms (in your original post).

I have no idea what you are asking.
