PV Electrical Testing: Test Setup

Initial test setup for electrical field testing a PV system during commissioning or O&M. Test setup for IV curve tracing and insulation resistance testing (IRT or Megger) inside the combiner box.

According to 690.31 A,
“Where PV source and output circuits operating at voltages greater than 30 volts are installed in readily accessible locations, circuit conductors shall be guarded or installed in Type MC cable or in raceway.”
So how come there are conductors exposed at what appears to be ground level? Is the back of the array fenced? I ask because I have seen this on many videos, and I have had to make sure that exposed cables I install can’t be reached from the ground. I achieve this by raising the mounts and installing the modules so their wires are above 8 feet.

Hi Jeff, thanks for your question. In the video we are behind a locked gate, in an area accessible only to qualified personnel.
