I have just installed a Vetus 75kgf bowthruster and need to connect up the battery or batteries which are located adjacent to the thruster.
Reading the Vetus instructions I require cables that are 150mm2 cross section area. To me this seems very excessive. In a previous boat I has a bowthruster that had much smaller cables (something like 35mm2). I can get 35mm2 cables made up very easily, but not for the recommended size. I can't even visualise the bigger size.
Are Vetus being too particular? Are they over specifying the cable size? I plan to use either a single 120Ah AGM battery or 2x 90Ah AGM batteries. The cable run will be under 1 metre.
What cable size does the forum recommend using?
