the threaded gland you can see with the wires exiting was meant to fit into a metal enclosure with a locknut inside, this would then pickup the earth from the cables copper sheath, which has a larger cross-sect. area than the core wires.
there is a plumbing style olive fitted onto the cable between the hex. nuts to ensure good connection to sheath.
The copper clip in use is a common way of making up for losing the earth when changing from metal to plastic enclosure, the cable may have plastic outer sheath over copper. scaling 20mm/ 3/4 inch gland makes me think you may have a 2.5mm cable, rated at 31Amps.
cant see where red&black go to but they need to be protected better,,,,,,sparx
