Can connector ends be left on mixed wire? I am not talking about the huge metal computer gold pin connector type, but the smaller plastic connectors, and the non gold plated three prong plugs on drop cords, power cords, etc. Thanks.

Leave them on.

There are still some smaller yards that buy cable at a different rate for without ends out of ignorance of true value.
And some of the largest yards have proper skills and volume. But over the last decade the trend has been to move to leaving them on.
There’s been, literally, hundreds of loose cable plug injuries per year. And most yards don’t play with that twice.
They’re hard to keep track of… at the processing level—The companies that actually strip them down and recycle them. They fly out of commercial shredders, usually prongs down, making tiny little bomblets. They get caught between belt transfers and fly off like missiles.
They get caught up in transfer and cleaning equipment and turn into large bullet slugs.

Unless the plug is larger than a tennis ball:
And Unless you’re told otherwise leave them on.


As a side note, if you find a plug buyer, and bring in a bin of plugs: watch where they dump them. If they add them to wire stores find a new yard. They don’t care about their employees.

BTW: Argus, the largest scrap materials tracker, reported over 500 injuries and 3 deaths in 2020 from loose plugs. Apx 22% of those injuries were life altering. That’s generally, paralysis, blindness, loss of limb. That’s more injuries than coal, oil, and ordnance (explosives).
Recovery Today reported nearly the same numbers.


In more modern systems (post early 2000s) wires are fed automatically and plugs are removed by machines that then feed them into separate processing that shreds them in enclosed or angled box shredders. Keeping a literal lid on expelled and ejected connectors.
In older systems wires are fed from the end. A large screening system crusts off and removes anything thicker than the wire, like plugs, knots, and tangles. That’s automatically binned and processed by hand.

Better safe than sorry.
