Fuse 22

[ice]

Has blown 3 times and for some reason the previous owner had a 15a not a 10a in there, i have put back a 10a in and disconnected the reverse light switch. The fuse is ok at the mo just gonna keep an eye on it and get myself a new reverse light switch.
Are these fuses like slowblow? The reason i ask is that ive had the car 11 weeks and the it decides to blow but it pops not straight away its really weird lol
Sorry if this is not making sense lol i dont quite understand what is going on Stu
