What's wrong with this picture? - Electrical

I found this disconnected conduit joint where the insulation on the wiring within had been cut by the edges of the metal and caused some arcing. This is a fire hazard that is intermittent - sometimes the circuit breaker would trip, sometimes it wouldn't.
Recommended resolution: Have a qualified electrician reconnect the conduit and secure it with conduit clamps, then replace the wiring.
Note that there are only two conductors (assumed to be the hot an neutral). This also exemplifies why it is a good practice to require that safety grounding conductors be installed in power conduits and not to rely on the conduit system for a continuous and uninterrupted ground path.
