Re: [RE-wrenches] Snap-n-rack bonding certification

Rebekah:



Thanks for your help with this.



Because I snapped up all of the 100 series rack I could (pun intended), I
am past the recertification with newer modules.  My argument is that
although the rail was discontinued, the clips remain.  What  I did is
extracted a page from the UR series manual showing testing with the Mission
panels and inserted it into the permit set.  I hope this sleight of hand
passes plan check.

Minor update, I got word from Snapnrack that: "The new protocol established
with UL eliminates the need to include the wattage ranges for each module
type"

Still a pain and the manufacturer/model should be on the rack manufacturer
list - but not down to the precise wattage -  so slightly less of a pain.

Hi William



Groan, I don't see that precise model in the series 100 installation manual
<https://snapnrack.com/wp-content/uploads/2019/05/S100-UL-Install-Manual_v2.0_web.pdf>
on
pg 74 which is the bonding evaluation list of modules

I hope for your sake Snapnrack will send an email the AHJ will accept that
includes that module.

I wish there was a reasonable workaround for AHJs here, like onsite
resistance measurements.



Good luck,

[RE-wrenches] Snap-n-rack bonding certification

2021-07-20 Thread William Miller 
Friends:



I received the following correction noticed from a hired plan-checker:



*Please provide the technical listing for the support rail system
documenting that the supports have been tested with the PERC 60 panels. The
UL 2703 listing requires the two to be tested/listed together for the rack
to functionally ground the solar panels. [CEC 690.43(A)] Alternately, bond
the metal parts of PV equipment to grounded metal supports per CEC
690.43(B).*



Is it true that UL2703 requires testing with each and every type of module?
I am using 100 Series rail from my stock with Mission MSE325SR8K panels.
Does anyone have any documentation on file that would satisfy this request?



I have sent an inquiry to Snap-n-rack about this but they often take a week
or more to respond.



Thanks in advance.



William Miller
