I have spent an uncomfortable morning checking cable connections that are not standard fit on our boat and require a mole to below the aft bunk.
A radio has been fitted at some time by a previous owner and a permanent supply to it provided by a redundant original cable. I found the only protection was a 35 amp in line fuse and holder just by the battery on a 0.5sqmm cable!
The same battery terminal post also had a standard webasto fuse holder and a 15 amp fuse. This was not original fit out. The webasto is rated at 14 to 29W so this fuse appears to also be oversized. The main supply cable for this is ghtly either 0.75 or maybe 1 sqmm.
I expect initial maximum power will be the higher wattage figure on start up but using a 15amp fuse seems a bit over the top. I will measure the current once I have extruded my post lockdown body back into the aft bunk space.
Anybody got any direct experience on a similar heater?
