The heat dissipated in the connector due to cable joint resistance may be calculated by multiplying the joint resistance by the square of the current passing through the connector. I would like terminate all the unused circuits wires in the electrical box panel with dummy circuit breakers rather than leave them dangling in the box. The test loop is subjected to heat cycling by passing a large AC current through it for a predetermined time, during which the conductor temperature is monitored. You should do this as soon as you remove it from the water before it gets cold and stiff again. I personally would ask an electrician to isolate the circuit, find where the cable enters the floor/ceiling void, snip it and terminate into an appropriate enclosure and secure in the void, then re energise.
