Fuse rating for 0.25mm cable
Discussion
Hi, Just a quickie I hope.
I'm wiring a solar charger into my car and cannot use the supplied lighter plug which has a 0.5A fastblow fuse as my Acc socket is ignition switched. It also came with crocodile clips which were un-fused.
What I have done for a neater setup is to mount a chassis socket to plug into under dashboard, tapped into the fuse box with a (piggy back) tap fuse.
I used the cable which came with the kit then thought afterwards that it was a bit thin.
The cable is eleven strands of 0.17mm diameter equating to 0.25mm2 with an insulation diameter of 2.5mm.
Question is, will it be safe to fuse this thin cable at 1 amp as it's the lowest blade fuse I can find.
I've looked up info for various cables and although 0.25 is a bit rare, the amperage ratings for them vary a bit. RS components show theirs taking 6A yet Vehicle Wiring Products show that their 1mm2 cable only takes 8.75A.
Any advice greatly appreciated.
