Hello. I have a situation where a fuse keep kicking back. The pic of the db is attached.  The one that always kicking back is the 20A one.  So the question is, can I change the fuse directly or i should change the wire first to 4mm?
Current wire size is 1.5mm. I think.

Hi. It was an old thing.  It happened whether i switch on my computer or nothing while I'm not switch anything at all. It kicked back like ikut suka dia. So my plan maybe upgrading the 20A fuse by changing it to 32A fuse. Is it possible the problem will still occur after changing the fuse directly?  Also that fuse goes to one 3-pin point and then loop for two more 3 pin point outside the room for washing machine use.
