Securing conductors with one hole strap

    This particular situation, I doubt it was all that necessary to provide additional securing that was done, but at same time I don't have too much issue with doing so with the 1 hole strap. If you are concerned about it eventually wearing through the insulation, put some wraps of tape in that spot, or even friction tape/rubber tape for a little thicker cushion at that spot. 1 hole strap is better than something ferrous that completely encircles the conductor - that sort of thing would create additional heating from magnetic effects.

      As for the EGC, how do we know that’s not a feeder tap and the EGC is sized for the OCPD ahead of it?

        By what we can see of the picture there are a lot of unknowns.....

        Is it actually an EGC ?
        Is it actually a Neutral Conductor taped Green?
        If it is and EGC Is it landed on the Neutral bar?
        If so is the bonding screw installed ?
        Are these actually Service Conductors?
        If so a Grounded Conductor is not actually needed?
        Are these Feeder Conductors?
        If so, why is the EGC so large?
        Is this a Tap?
        If it is a Tap were they actually sharp enough to know about upsizing the EGC ?

        ETC.....

          I never thought of that ... thanks.

            I would say, in a sense, they have created a ferrous ring around the conductor with the 1 hole strap.

              I have seen panel cover screws penetrate the insulation on service conductors.In our neck of the woods ,we have in the past been asked to fasten the conductors in a like manner.Typically a plastic strap is what we use.And we work in the southeast primarily.

                That really looks terrible to me.

                The one hole strap, the inconsistently bent wires, wires up against bolt heads/threads, and the double/triple stacked washers under the 3/8's bolts screams inexperience to me.

                It really only takes a few minutes to do a good job, such that it looks like a professional was paid to do the work.

                I'm probably being too harsh, but that would be getting redone in our shop.

                  A two hole strap (with a screw in both holes) at least has a completed circuit, the one hole strap has an air gap in the "encirclement". It may have some magnetic effects but not the same as if it were completely encircling the conductor.

                    It may not be neat enough for some, it certainly isn't the worst thing that can happen.

                    I don't see the real need to use that strap on that one conductor, but at same time have no real issue with doing so if needed to keep it in place, usually needs to be much larger enclosure for that to be much of an issue though. I have done this - usually with PVC conduit straps though.

                      I've never witnessed the whole magnetic effect thing that everyone talks about, and, I've seen tons of ferrus entrapped conductors.

                        It is there, but may not have any extreme effects in anything you have seen. I haven't really seen any extreme effects either that I can recall.
