No and No. Both of these will potentially cause stray current leakage into bilge water, which can eat metal very fast. Usually I don't solder DC power wires, but my bilge pump wires are soldered and heat-shrinked to be totally waterproof where they are exposed to water. I would also move that junction block up higher.

In the process of wiring in my new high water alarm, I found it convenient to split an existing always hot red wire in the bilge area to run both the bilge alarm and the emergency bilge pump switch. I had some 3 way fittings from Defender (below) that I have used before which have crimp/heat shrink attachment ports. After connecting them I realized that the center part of the fitting is actually not insulated. This seemed like a bad idea, especially for a potentially wet area like the bilge. I am confused by the logic of a sealed connector that has an unsealed junction exposed. In the past I used a larger crimp/shrink butt connector and stuck two wires into one end and now that seems like a better solution. [BSP Clear Seal 3-Way Splice Connectors] 2. There is also an open connector block for all the mast wiring in the same area of the bilge, so high water would get to that area at a similar time as the alarm or emergency switch. So is that considered an OK way to set up mast wiring in a wet area? Thanks- Dave S/V Aries 1990 C&C 34+ New London, CT [cid:image002.png@01D53676.A4C2AC40]
