@Howzat - I got the right one 6 AWG
All sorted now. Looks like human error potentially or renogy being very 'touchy' - two elements checked additionally:
1. changed fuse from the one that came with the fuse mounting (I didn't trust it in the first instance)
2. noticed my error - I switched off main switch and switched it back on within 10 seconds - there was over 15A on the lead and further added by swiching back on - fuse blown. Unusual I know but verified with clamp meter, just to be sure - created surge therefore.
3. I have changed inline fuse to midi one anyway just in case so I do not have to come back to it again.
@Dellmassive - thank you for pushing me to check futher with clamp and settings!
6 AWG is 100amp fuse to be ultra safe so that should cope easy with any surge. Glad you got it sorted.
The destructions for the Renogy 50a DC to DC MPPT indicate I'll need a 75a and a 65a fuse - can someone point me in the right direction for these please?
The fuse needs to be sized to protect the cable..
Assuming you have the correct cable gauge.
You can use MIDI fuses and holders.
.
And
80A here..

The cable from starter battery is 25mm2 which I believe is more than enough.
So I assume I'm ok to go for 60a and 80a rather than 65a and 75a ?
