Surely someone sells such a thing?
I have made my own out of UHMW plastic and screws and fiberglass rod with springs so far. There was a recessed hole to insert the Unit To Be Tested's power cord wires into.... then the fiberglass rods press the strands against the contact screw within the plastic block, which is fed from a contactor within an enclosure. A 5th fiberglass rod enters the enclosure and operates a switch such that power is applied to the terminals only if the pinch rods are pressed against the wires/ terminal screws. The wire access holes are about 3mm diameter and the terminal screw is about 6mm down in, so a finger could not access the terminal in any event, nor can a dropped tool cause trouble.
We need to test 240V-1Ø with 3 wires [L-L-PE (Protective Earthing)], and 240V & 480V 3Ø 4-wires [L-L-L-PE]. The cables are Carol brand rubber coated SJOOW in 14-3 or 16-4 configuration; max expected amperage is about 5A per leg. We only need power the Device To Be Tested for a few seconds and verify speed, direction, and current draw.
I would prefer something like a heavy duty spring loaded clothes pin type apparatus that can grip each wire and hold it as the operator connects them. Similar to a connector I have seen on audio speakers, but for high voltage and maybe 10A capacity.
I can arrange some sort of safety to ensure that the power is off if hands can get near these connectors- e.g., an enclosure with a lid that cuts off power if the lid is open, like the above described tester connector.
Anyone know of a source for such repeated-use test machine terminals? I have tried searching the internet, and obvious places such as DigiKey.
Thanks so much for any assistance.
