Very nice. One thing I’d mention is that sufficient durability doesn’t mean it has to last for the lifetime of the system. It’s an item on O&M inspection checklists - “all labels/placards/directories are intact and legible” (with the presumption it’ll last until the next O&M inspection.
Of course i get it: residential and even commercial systems often aren’t getting regular “checkups” so to your point, it is important to pick something good that will last. My point is: even if it’s not forever :) Brian > On Jun 27, 2020, at 12:40 PM, Jay <[email protected]> wrote: > > Hi Corey > > Well done. > > Question > > What is the orientation of this test? > > Jay > > Peltz Power. > >> On Jun 27, 2020, at 10:59 AM, Corey Shalanski <[email protected]> wrote: >> >> >> About ten years ago we set up a test wall of sorts at our company >> headquarters in New Orleans.
