1. Use quality cable
This involves avoiding halfords , yeah I know they open on Sunday's ,but they stock total shit , they source Chinese shit , wherever possible as it maximises profits . -Avoid
Cheap Chinese cable use a plastic outer insulation , this has poor fire resistance , read about as close to zero as is possible , it also has poor conductor wires - so the cable has to be thicker as a result .
The longer cable run at high current can drop voltage along its length .
Quality cable will be at least 2 cable sizes thinner , carry the same current , has insulation good to 400volt plus (despite being thinner) and will withstand a direct short circuit or fire for 10 mins - this gives you time to pull over and switch off ignition .
A circuit breaker is a good idea , next to the battery , and quite cheap around £25 , breakers need to be in open air if possible ( not buried under carpet or such ) as they are thermal devices .
Fuses and breakers actually pass more than the rating on them but only for fractions of a second and if too warm will keep tripping as a nuisance - breakers are better than fuses .
Try a test : get 3 inches of halfords cable and put under a fag lighter - watch what happens = your car full of black choking smoke and on fire !!! - causing more short circuits as it burns !!

Panel mounted , although a bit bigger and needing a panel making would never trip - these they fit in aircraft - it would be disaster if every CB tripped on landing .
My car came with the battery relocated and is both poor cable and unprotected - another job to do , any short will give over 1000 amps and weld the cable , much smoke and drama !
I would guess that the insurance would not pay out for a total loss
Some cars have OEM boot mounted batteries and will have fusible links , you could use cables and links etc from one of these from the breakers - Mini Cooper s , Volvo , merc , BMW etc

What is the general size 60-80A or ?

There is a factor for starter current usually around 3 , ( any fuse or breaker takes more than it's rated amperage for a very short time) this happens due to something called back EMF (everyone's asleep now - lol) it's a small engine , so I would say 100-150 fuse breaker should cover it .
Once upon a time I had a classic mini , and the engine earth came off , probably rusted off , and it decided to use the choke cable as the return - FIRE !! , smoke pouring out of the dash and bonnet ...:..
After that I've always fitted a fire extinguisher either front of drivers seat or in the boot .
All my jap cars seem to have a boot release , they must have known you can run to the boot and leave the key in the ignition -lol
Saying that , I've not yet fitted a firex to the pulsar .....
Strangely if you tell your insurance , they put up your premium ..... Non OEM standard fitment ??????

Unfortunately wise buying seldom happens with car wiring/ electrics , often many thousands are spent and many hours spent choosing car components . Cranks , pistons ,cams , ecu and so on , but the wiring ... About £4.99
