(8) 4" in (8) 4" out. Thinking of somthing like the utilities use, we call them coffin boxes, they have a base that the conduit come into from below and an above ground area for splicing.

They list an 8-port 500 kcmil, maybe 750 is available:

Nice job on the links!

I think the OP is looking for something like a PSE&G pullbox (coffin) AND something 'above ground' to splice in.

The PSE&G spec is precast concrete, 4' deep, 4' wide and 71/2' long. 4 over 4 in and out works nice.

Take care

The company I used to work bought custom made boxes from a fab shop. This fab shop - all they did was make metal troughs and boxes. Indoor or outdoor. They even provided POCO approved CT Cabinets for less $$ then the POCO.
I was told "if you draw it out and / or explain it to us - we can make it for you"
I put them to the test too. I had some interesting troughs made!
Might be worth the search to see if such a thing exists in your area.

Good stuff Ken,
When I was doing dairy stuff we always fabricated our own Stainless steel "enclosures", all you need is a sheet bender, a clue as to what you are doing and a TIG welder to close up the sheet joints and make the thing water-proof and look nice, of course.
Most fabrication places are only too happy to build a one-off provided they get good plans of what you want and a time frame of when you need it.

My only reservation would be, would an independent enclosure be " UL listed" at all?
Would it need to be?

I have used custom troffs (wireways) when needed, fabed by a shop that also made switchgear and panelboards. Excellent end results, based on field dimensions. He was very cooperative and performed all field measurements. UL labeling was not an issue, all equipment was labeled.

The sticky side was...$$$$. Not a source if you had budget constraints.

Mike (Trumpy) did you do the fab yourself? Or do you have a welder and bender on staff?
