    As to the two conductors in the green/yellow (PE) terminals, there is some widespread confusion on that issue. There are some manufacturers out there that, under IEC rules, say that you can have up to 3 conductors, so long as the total cross sectional area doesn't exceed the design of the terminal. So people read that and think it's OK.

    But here, the use and listing of the blocks falls under UL and ALL of these IEC style DIN rail terminals are only UR (Recognized Component), meaning they can ONLY be used in assemblies that themselves will be UL listed. In that process, UL will NOT allow more than one wire per terminal, unless, in sync with the NEC, it is explicitly LISTED for that, and the UL file for IEC DIN rail terminals doesn't allow that. So despite the fact that the TB mfr may say it's OK under IEC rules, that becomes irrelevant here. I used to work for a company that sold and used IEC terminal blocks, this was a constant source of pain and confusion.

    I just noticed I've been spelling DIN rail with an e instead of an i

    My bad.

    I was tempted to poke fun at you on how particular you said you were when making up such things yet you can't even spell some of the components correctly

    I'm glad you didn't.
    I know you're in the farming community,, I'd come charging at you with a bindicator if you did that.

    Wonder how many that participate here know what a bindicator is? I'm talking original product that has bindicator as a trademarked name, there may be other items that get called that at times, as well as other items from same company that have that name associated with them.

    Doesn't matter as long as you know what it is. No one else called me out on my bad grammer.
    I guess I could blame it on the auto correct thing.

    And yes I did mean the roto type.

    Seems you do know what they are then.

    Do you know what a "Stirrator" is or a "Shivvers" system? Both those becoming things of the past, how about more modern "power sweep"?

    May I ask what kind of equipment this is and the name of the manufacturer?

    Just curious as I used to work for a manufacturer of drilling equipment.

    Do not.
    My 1st day on the job in my electrical career was on top of a grain bin installing a bindicactor with the motorized paddle. Then onto the limit switches for the indicator lights in the distributor head on a 130' grain elevator then to the vibrators to rattle the stuck feed out then to the pulse socks on the dust collector then to the controls for the cyclone blender then to the shaker for the fines and overs then to the size 5 soft start for the pellet mill then to the controls and interlocks for the auger under the mixer then to the load out auger under the scale then to the mollasus blender then to the air compressor controls then to the size 4 starter for the hammer mill then to the to the ....... oh well you get my point.
