I have to test over 100 units of a device that runs at 480 VAC. The device will have a stripped 3-conductor cable (L, N, GND) coming out of it, no connector. Power is minimal, less than 1/2 A.
I am looking to build/buy a simple rig to do this with minimal fuss. These are my specs at the moment:
- Power switch for safety
- Easy plug in and out
I will probably add AC current and voltage panel meters.
My current concept is to use a NEMA L8-20 twist-lock plug with a short length of flexible cord and Wago 2-pin lever connectors on the end. Something like this:
https://www.mcmaster.com/7162K65/https://www.wago.com/us/wire-splicing-connectors/inline-splicing-connector-with-lever/p/221-2401Procedure:
- Connect L, N and GND to the twist-lock connector: Flip all three levers; push wires in; flip levers down
- Connect twist-lock to test rig
- Flip the switch and go through test procedure
- At the end of the test, turn off, reverse procedure to disconnect
In other words, three layers of safety: 1- Power switch; 2- Twist-lock is disconnected while attaching to device; 3- Wago splicing connectors
Is there a better approach? Both speed and safety are important.
Thanks,
