    The fact that this is temporary is understood.

    The use of staples between buss sections is not really a good connection and may well arc and damage the buss sections (other than looking rather unsafe).
    I guess I wasn't defending the use of the staple as a jumper but did not make that clear, I was simply stating a possibility of why they were using such a low ampacity supply. If permanent supply conductors are not installed yet simple solution to connect both buses is a jumper between main lugs or maybe between output lugs of a double pole breaker (that is not a MWBC) you aren't going to run whatever load is connected to that breaker anyway.

    Many won't be all that particular with one wire per terminal with this temp setup anyway and may install jumper between terminals of same breaker they are backfeeding, or some breakers may have two wires per terminal rating anyway, such as QO/Homeline that are 30 amp or less.
    I live for today, I'm just a day behind.

    Enlarging the photo to 300% shows the device better. The device appears to slide on the bus. The "staples", wire jumpers, look like they are welded to the slide on connectors.

    Seems like a lot of time was spent on making the shorting device if its' only purpose is to connect/tie the L1 and L2 bus together to temporarily feed the panel with 120V.

    Also notice there appears to be at least 3 female connectors that are installed on the bus. I can't make out exactly how or what the bottom jumper, "staple", is connected to?

    Were they installed at the factory?

    Field installed, I’m sure. I didn’t notice damage of any kind and my help didn’t mention any when he removed them.

    Do you think it was made in the field? I don't see how.


    Is/was it a welded together assembly? Did your worker save the thing? If he didn't destroy it when he removed it from the panel, and maybe saved it, can you take a close up picture and post it.

    Also looking closer to the 300% enlarged picture what is the bottom jumper, "staple", fastened to?

    They were wedged between the stabs. No welding. Nothing nefarious, just FE.

    I can hardly wait for the you tube video. "Temp. Power made easy".
    The 95% of people that you can't trust give the other 5% a bad name.

    What is the current rating of those staples? What is their AWG equivalent?

    They are parallel in open air so take that into consideration.
