[RE-wrenches] (no subject)

[Bill Brooks]

Read 690.9(D) and 690.34. Not sure where this "hysteria-run for the border"
sentiment is coming from.

 

690.9(D) Photovoltaic Source and Output Circuits. Listed PV

overcurrent devices shall be required to provide overcurrent

protection in PV source and output circuits. The overcurrent

devices shall be accessible but shall not be required to

be readily accessible.

 

690.34 Access to Boxes. Junction, pull, and outlet boxes

located behind modules or panels shall be so installed that

the wiring contained in them can be rendered accessible

directly or by displacement of a module(s) or panel(s) secured

by removable fasteners and connected by a flexible

wiring system.

 

This is not a change. Please help me understand the concern.

 

Bill Brooks.

Interesting so does "require a tool" include taking a screw off the cover
plate of the combiner box, too?
What a game changer.  I'm going to Mexico for my next project; I'll actually
enjoy even more being the sole AHJ on the project.

Readily accessible is now defined in the 2014 NEC. Installing OCPD's
underneath a module is a major faux paux, and I can't imagine any AHJ
thinking otherwise. Having to remove a module in order to reset a breaker,
what a drag.

 

"Capable of being reached quickly for operation, renewal or inspection
without requiring those concerned to use a tool, to climb over, remove
obstacle or other."

You call it a solar panel, I call it a glass j-box cover plate.

If that is the interpretation,
I don't see how the breakers are "readily accessible" in a SolaDeck
mounted anywhere, regardless of whether it is under a module. It
requires removal of four screws (using a tool) to access the breakers
inside the enclosure. It's all up to the AHJ. It has not been an issue
locally here. I can see how other jurisdictions may not
concur.
