Why don't we seem to have a standard colour coding for standard type fuses? [Linked Image]

This applies especially for New Zealand but I have no doubt that other countries have similar issues.

I find it quite often a pain when for example HRC fuses ( 2 to 40 Amps ) all have the same colours printed or labelled on them.
The same applies to the bigger sizes too and also the actual AMPERAGE is written on it too small while all the other info is usually printed on too big. [Linked Image]

and to say I have excellent eyesight. [Linked Image]

The older NZI plug in MCB's at least are colour coded.
White 6 amps
Grey 10 amps
Blue 15 amps
Yellow 20 amps
Black 27 amps
Red 30 / 32 amps [Linked Image]

I personally find colour coding a lot more effective than applying all the same colour.

The older European diazed weber style fuses had a similar colour coding and an indicator which popped out behind a little glass window if a fuse had failed.
DII style: Green 6A, Red 10A, Grey 16A, Blue 20A, Yellow 25A.
DIII style: Black 35A, White 50A, orangegold 63A. etc.

These were the values I most dealt with while above 63 A mostly DIN style fuses were used.
See what your opinions are.
