Hi, I just bought a Mariner 420 2004. The shore power cable is a 50amp 125v/250v cable. When I took possession of the boat it came with a 30amp 125v to 50amp 125.250v pigtail. With this cable everything on the boat is working fine. I can power shore 1 and shore 2 with it. Although we are tight on power when the 3 air conditioning systems are on and drawing power.
I bought a Reverse Y cable 2x30amp (shore side) to 1x50amp (boat side) - model marineco RY504-2-30. When I use this cable the main breaker on the boat trips immediately.
Any idea on why this would happen?
Thanks in advance for your help
Laurent
