In Unite and below, you make a shock trap with Genprey Fangs - which aren't electrical, they just contain a potent neurotoxin. Perhaps the Shock Trap is a small fly-wheel with Genprey fangs attached to ropes - if it slams into the monster, the monster gets paralysed. As for why it doesn't affect the hunter... maybe the Hunter has an antidote on them at all times, but they didn't bother with the whole animation of taking it every time you walk into your own Shock Trap (understandably).
