I've always interpreted this rule to mean to the wiring, not to the
bottom edge of the array. 110.27 refers to live parts; that's actual
uninsulated bare conductors, lugs, or switch contacts, etc. Further,
690.31(A) just says "circuit conductors shall be guarded" Finally,

I would give a small amount of additional time to convince the
inspector. After that I would build the fence he wants. I would also build
it to be easily dismantled/removed. Good Luck!

Thanks all. The NEC reference 110.27 is helpful.
I am in a battle now with my AHJ building inspector which relates indirectly to
the 8' rule question. I have mounted several modules awning-style above a
window at an angle of 30 degrees. The bottom of the array is 7' from grade. The

We’ve had good experience with the TS4R-Fs. Straightforward installs although
wire management is more cumbersome than micros.
Since they’re Sunspec compliant no need for a separate RS initiator. AC
disconnect is all that’s required.
Too early to give feedback on long term reliability. Hope
Wrenchers,
Does anyone have feedback on using TS4R-F for rapid shutdown? It was a
tough run for us with RMA's on the SMA Rapid Shutdown boxes. We never
messed around with Tigo but have followed threads here, and recently had an
SMA tech tell me "he wouldn't wish it on his worst enemy". Probably
The discussion about an 8 ft rule is in regards to accessibility, not physical
damage.
Two completely independent topics…

Hi
Simply, the '2.5 m' (8 ft) has been inferred from Article 110.27(A)(4).
It's interesting now that the distance in the 2019 CEC/2017 NEC has
increased based on voltage. In other words, if the voltage is greater than
301 volts the minimum would be 8 ft 6 in. :)
All the best,
