Why Welding Cable Should NOT Be Use on Boats
These photos are from two different mid to late 80's Taiwan built trawlers.
Photo #1 was the B+ feed at the battery switch on the panelboard. Photo's #2 and #3 were from a different boat and were in that boat's main B+ feed to the battery switch on the panel board. Both of these defects were hidden behind vessel structure that had to be cut away to gain access. The defect in Photo #3 was "repaired" using a wrap of electrical tape. Note how, even though the defect was wrapped and inside the vessel's structure, moisture had corroded the uber thin, un-tinned strands of wire.
