One of our fuses in our secondary fuse box just blew. Luckily, there there is a backup. I am not an electrical professional but I know a little 101.
I just want to ask about the correct fuse / amps to install if I have this kind of setup:
As I said, one of the small fuses just blew and I replaced it with a 30 A fuse. Is it safe to use 30 amps? Because when both of my aircon and computer is on, the fuse copper was sparking. I am not sure what's causing it - is it the contact between the fuse holder and the fuse, or is it the fuse itself that just can't handle the current flowing? I noted when I turned off my PC, I don't see any spark.
Anyway the fuse I was using is this:
I am using 30amps, I think those are the big ones installed in our main fuse box.
Can you please give some advice about proper installation and what type of fuse to use?
