The cable (round with a black covering) that feeds our electric range
has no markings that I can make out, but the breaker is a dual 40A, so I
guess the cable must be 8-3 (or bigger) + ground.

What is the approved means of securing this where it runs across the
joists? At present it has nails hammered in on each side and bent toward
each other forming a "two-part staple"! I am sure that this cannot be
kosher, but I can't find anything that is marked as being for cables
this large.

What should I be looking for?

Plastic plumbing strap and appropriately sized nails works pretty good.
Also, hangers for 1/2" plastic pipe or conduit might work (especially
the ones for CPVC cuz they should be about the right size)

Home Cheepo has plumbing hangers. Bought some today. Measure the diameter of
the wire, go buy some clamps and some drywall screws or something.

I found staples for round wires that large at Agway, a
farm parts store. Perhaps same in your area.
I moved such a cable in my basement; a feed to
another panel - and the inspector just glanced and
nodded as he walked along it, tracing it. He also had
no comments on the nails inthe first ten feet, which I
didn't have to move, but he inspected the bends quite
carefully.
I wouldn't use flat staples for a round wire - too
many pressure point damage possibilties.
Someone mentioned PVC hangars; I thought that was
good, too, actually, if they really can be made to fit.
I've used them for just about everything else <g>.

HTH,

Pop

It's not kosher, but not that unusual I suppose.

Staples for wire this large are available, but you may have
to go to a real electrical supplier for them.
