Can anyone recommended a fuse holder brand please?
I have had issues with both 60amp fuseholders available in my local town.
The first was prefab but the wires were only rated to 40amp...
The second option was for a inline glass tube style which fails to pass any current at all.
I would just like to buy the best option available.
60amp fuse. Wire is 4mm 50amps
4mm wire is generally rated around 30A. Putting a 60A fuse in the circuit would be dangerous.
Doing what you suggest will turn your wire into the fuse and cause major trouble for you...including a potential fire. The fuse is protect the wire, the fuse should be rated at a lower amperage than the wire to protect the wire.
MEGA fuses are great, AMI/MIDI fuses are as well. Even ANL fuses are fine in the right application. And all of them have holders available...some are high quality, some are crap. Going with a company such as Victron or Blue Sea are top of the line. There are plenty of good fuse holders; decide on defining the application, then identify the correct fuse type for the application. Once that is all done, look for the best fuse manufacturer you can find. It is better to spend a little more for top quality...than rebuilding a system later that has been ruined.

Have you considered circuit breakers?
Agree 100% with comments.
