Robin,
Well, I think I got myself into trouble here. I do remember a recent conversation with you about this - I think - and this is the message I remember from that conversation - I think. Perhaps this is all in my imagination. I am getting older, certainly, so senility can't be far off now.

I haven't used Outback's SmartRE, but on their older PS1, the row of breakers was out front, and was thus within the required 6" of the plane of the front of the battery cabinet, and thus met the working clearance required by code when sealed batteries were stacked beneath. The E-Panel breakers are back far enough to be outside of that allowable 6". That's all I meant - it has nothing to do with the listing of the hardware, more how it's installed in relation to other equipment and code compliance.

I seem to recall you telling me that nobody had ever been rejected for this reason. While I never have, neither have I installed a cabinet of sealed batteries under an E-Panel; most E-Panels I have installed have battery enclosures off to one side, or through a wall.

Robin, is it code compliant to mount an E-Panel above a 15" deep battery enclosure, given the breaker location?

No harm intended.
Thanks, Allan

Ray,
I don't think Robin has posted anything, it just came in a conversation we had. As I understand it, service equipment must have nothing interfering with designated working clearance, within a few inches of depth allowed. With Outback, Magnum, and Xanschneider the breakers are on the front surface and are within the allowable depth. Midnite/Magnum and Midnite/Outback places them back toward the back wall with the inverter on the hinged cover; thus the battery enclosure technically sticks out too far. The XW Midnite panel doesn't have this issue, as it's a different layout. If necessary, one solution would be to mount the E-Panel several inches out from the wall surface.

Why does the side mounted breakers make the Midnite non compliant?
Apparently I missed Robin's post on that.
Or do I not want to know?

Thanks,

. Midnite enclosures, with the breakers on the sides, are not compliant, as Robin has acknowledged, but it has never been a problem for us as the breakers are still easy to access.

Allan, I don't remember saying our equipment is not compliant ?
The battery cabinet cannot obstruct access to the equipment.
The fact that the MidNite breakers are on the side actually
allows better access to servicing them.

The front facing breakers have the connections on the back of
the breaker where you can't see them.  Our breakers are clearly
visible for all the connections compared to all of the alternatives.

The battery boxes stick out 15" from the wall.  This is all the closer
you would be even if there was no battery box under the E-Panel.

Robin
