I used Solarscrim to protect the underside module wiring of the array on one job. Good product and support and reasonably priced. Allan On 7/20/2020 11:16 AM, Sam Haraldson wrote: Much like Ray we have interpreted this protection to mean the "dangerous" parts of the solar and not the module

Wrenches Much like the coroplast we have used corrugated sheets that we have cut to "pop in'' to each panel, not done for aesthetics but rather to protect the back sheet from animals but we did see a temperature increase as a result. Jerry NABCEP Solar Inspector On Mon, Jul 20, 2020, 10:16 AM Sam

Re: [RE-wrenches] protecting wire below 8' w/awning array

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, if the

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! Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgridsolar/ [1] e-mail

Re: [RE-wrenches] protecting wire below 8' w/awning array

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 inspector

Re: [RE-wrenches] protecting wire below 8'

The discussion about an 8 ft rule is in regards to accessibility, not physical damage. Two completely independent topics… Glenn From: RE-wrenches On Behalf Of August Goers Sent: Friday, July 17, 2020 10:32 PM To: RE-wrenches Subject: Re: [RE-wrenches] protecting wire below 8' Hi

Re: [RE-wrenches] protecting wire below 8'

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, Martin Herzfeld,

Hi Kirk - We work in San Francisco where they have a local code amendment: 300.4(I) Add the following section: (I) Subject to Physical Damage. Premises wiring systems installed less than 2.44 m (8 feet) above

Re: [RE-wrenches] protecting wire below 8'

Yes but see Article100.1 for the definition of accessible and readily accessible, to access you need a ladder. implies I think where the 8-foot idea come from I think this is poor writing, but it is accepted to be beyond reach On Fri, Jul 17, 2020 at 11:02 AM AE Solar wrote: > Kirk, > Not sure

All, Is there a reference to this so-called "8-foot rule" that someone could point me to in the NEC? Thanks.___ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings:

Re: [RE-wrenches] protecting wire below 8'

Kirk, Not sure if this helps but 690.31(A) “where PV source and output circuits operating at max system voltages greater than 30v are installed in readily accessible locations, circuit conductors shall be guarded or installed in a raceway” It doesn’t mention 8’ but mentions “readily accessible”.
