difference between sprinkler valve box and electrical splice box

What is the difference between a 10" round box designed for electrical splices outdoors vs another of similar size and construction but it's a sprinkler valve box?



The sprinkler valve box is $12.

The electrical round box that looks the same, is $45.

Sprinkler box is bottomless and you install over the valve underground.
Electrical box is encased all the way around and you drill holes as needed for conduit.

I do not mean a regular electrical box, I mean a round hand hole box that looks exactly like the sprinkler valve box for electrical splicing. Those are open at the bottom. This is a link to the $45 one with a cut sheet PDF.

Nothing really. Mostly it is just the labeling on the outside of the box. Sprinkler boxes will say "Irrigation" on them while electrical boxes will be labeled "Electrical". I have also seen some boxes without labels.

It looks like the splice boxes used for electrical are CSA listed.
That would mean the electrical splice boxes are rated for electrical splicing
while the sprinkler ones are not rated for high voltage splicing.

That's what I thought as well, but I am no longer sure if that's the case. For one thing I have examined one electrical ground box and I saw no listing or rating on the actual item itself inside and out or on the lids.

Then I started to look online, and I got the feeling these boxes if they have a "rating" for something it seems to be a rating more for it's strength to withstand being walked on vs being driven over, like can I put this in a yard that cars will drive over it.

In addition, even though some retailers online or local sells a particular box as labeled "ELECTRICAL" or "WATER" or whatever, I found that when I looked up that brand and model, and trace it all the way to the manufacturers themselves, where I can pull up a cut sheet or spec sheet, more often than not, the manufacturer's spec sheet offers this box in more variations then the retailer. For example, look at this link:

https://www.ndspro.com/PDFs/Standard...ARD-SERIES.pdf

and this one:

https://www.scottelectricusa.com/img...pdf/433040.pdf

These boxes are available in different colors (green gray brown etc...) and the cover/lids are also available in different markings and it can be ELECTRIC, WATER, RECLAIMED WATER, IRRIGATION, SEWER, CATV, GROUND or nothing at all.

If the labels are all interchangeable, I am more inclined to think they don't matter.

Generally, each device leaving the factory with a NRTL mark incurrs a charge. If an inspector doesn't find the appropriate mark, you fail the inspection.
