I need to cover exposed high-voltage, high current terminals in the glider fuselage.
My index finger and pinky are pointing to the terminals. They will be at +115VDC with respect to ground when the battery pack is connected. The safety fuse is rated at 325 amps. A 'mere' short to ground at 250 amps will keep on smoking, and smoke in the cockpit is scary bad. This is a good reason to fly with a parachute.
The second photo shows a potential solution, which was molded on a discarded paint mixing cup of the right size.
Hmmmm, what do high-voltage high-current terminals look like in an EV auto/truck? Do they have fancy thick boots for insulation?
