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
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)
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
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>.
There are galvanized metal straps that take a nail in each end, go out
side and look at the straps on your service entrance cable, they make
small straps just like those buy at whole sale elect., or a hardware
