If you want a warning that circuits are tripping the circuit breaker then you just wire an LED and resistor across the breaker (so it lights when tripped).
Always the best way ie: Soldering the connectors. Never had a failed connection/splice after doing it.

Well, maybe. The American Boating and Yachting Council (which comes up with a lot of the marine standrads in the US) disagrees:

paraphrased from the ABYC standards, from :
Another common misconception dictates that the best of all connections is a soldered connection. However with stranded wire, the solder bonds the individual strands together, making a solid, inflexible wire. ABYC standards prohibit soldering as the sole means of making a connection because the newly solid wire is subject to cracking or breaking through vibration and flexing. A more practical solution is to use a crimp connector described above. Wires should never be joined simply by soldering and taping (or heat shrink); however, if solder is used, use only 60%/40% rosin core or solid solder, soldering after the butt connector is crimped. Acid core solder as used in plumbing may never be used in any electrical wiring.

Probably more relevant on RIBs which subject wiring to more vibration than sailboats.

That said, I solder and heat shrink as well, depending on the application.

Agreed - it is best to join mechanically (twist wires together or crimp) before you solder and then cover in waterproof heat shrink insulation.
