nickfryer Posted June 25, 2016 Report Share Posted June 25, 2016 Hi all As the tile any problem putting in line fuses or a small 12v fuse box into the side of the battery box. These would be for bilge pump, webasto and Smartgauge which all need connecting direct to battery but need to be fused Just trying to keep things tidy Cheers Link to comment Share on other sites More sharing options...
Guest Posted June 25, 2016 Report Share Posted June 25, 2016 Ive just installed a Smartguage and the manual specifically states not to put the fuses inside the battery compartment. I ended up putting mine just inside the cupboard below the door which is just above the compartment itself. I'm not sure if this is correct or if this still counts as being inside the compartment, but it'll do for now until someone corrects me. As for the reason it states not to put them inside I don't know, you'll have to wait for more experienced folk for that info. Link to comment Share on other sites More sharing options...
Robbo Posted June 25, 2016 Report Share Posted June 25, 2016 (edited) Blue sea do a terminal fuse block for this. http://www.sailsmarine.com/ItemDetail.aspx?c=211415&l=g&cc=GB Edited June 25, 2016 by Robbo Link to comment Share on other sites More sharing options...
NMEA Posted June 25, 2016 Report Share Posted June 25, 2016 Personally I would not put any fuse in a battery box unless like the Blue Seas M.R.B.F. it is ignition protected. Link to comment Share on other sites More sharing options...
Tony Brooks Posted June 25, 2016 Report Share Posted June 25, 2016 Personally I would not put any fuse in a battery box unless like the Blue Seas M.R.B.F. it is ignition protected. Which also means it is protected from corrosive gasses and acid droplets small enough to float about in air. Link to comment Share on other sites More sharing options...
Tiggs Posted June 25, 2016 Report Share Posted June 25, 2016 When a lead acid battery is charging it emits hydrogen gas (especially when over-charging). When fuse blows it can be a source of ignition. Put them in the same box and BANG! Link to comment Share on other sites More sharing options...

Can you expand Blue Seas M.R.B.F into something I can search on? Link to comment Share on other sites More sharing options...
nicknorman Posted June 25, 2016 Report Share Posted June 25, 2016 (edited) Can you expand Blue Seas M.R.B.F into something I can search on? blue sea mrbf into google gives lots of relevant hits. Anyway, marine rated battery fuse. (note, blue sea, not blue seas) Edited June 25, 2016 by nicknorman Link to comment Share on other sites More sharing options...
nickfryer Posted June 25, 2016 Author Report Share Posted June 25, 2016 Blue sea do a terminal fuse block for this. http://www.sailsmarine.com/ItemDetail.aspx?c=211415&l=g&cc=GB The idea was to use just such a fuse block as this but it looks like it will have to be fixed to the outside of the battery box. The battery box is well ventilated and is mounted on the swim right next to a large vent grill to outside. Link to comment Share on other sites More sharing options...
system 4-50 Posted June 25, 2016 Report Share Posted June 25, 2016 Blue Sea seem to make low value battery-mounted fuseboxes that are not hydrogen safe (marine rated) or 30A+ ones that are. Is the implication low value fuses do not create a significant spark??? Link to comment Share on other sites More sharing options...

Is the implication low value fuses do not create a significant spark??? Depends on the fuse type. Filled ceramic types are fine but the open fuse element blade type can make a quite impresive spark especialy if caused by a short rather than a steady overload down stream.
