Ebay can work out really cheap for stuff like this. Otherwise yes i've bought marine grade 2core wire from jaycar.
They also sell the heat shrink that has the hot glue sealant inside of it. I?ve tried the liquid electrical tape and I?m not a fan.
Generally Jaycar is cheap Chinese junk and likely not suitable for long term use in a marine environment. If you really want the best for your boat then may I suggest you cast your net further than your nearest Jaycar or Altronics store and try specialist marine dealers ....and even then look very closely at the quality of what you are considering to put on your boat. ..... Above all ...Caveat Emptor.
Well I changed the fuse box over to the other one. I'm happy enough with what I have there reasonably water proof on the back and the fuse cover has a seal inside the lid and Ill spray every thing with a good quality spray which Ill buy at work . Where this is going has nothing to do with any of the yachts nav lights anchor light or navigation system thats a separate system altogether or any thing to do with it . Ill use a expensive blue seas DC panel for that.
Meant to add this is for some strip LED's that will be fitted inside all the storage compartments on the boat . Example would be under the settee birth's
it has a maximum of 25 amp
