That's the same color code as used here, with the exception of 27A, which I've never seen before. Is that a peculiarly Aus/NZ rating?

Pauluk: this 27 Amps MCB was used for the 4mm² or imperial equivalent wiring for short runs to ranges. ( now these days superseaded with 6 mm² and 30A or 32A MCB's).

4mm² is now protected with a 25 Amps MCB.

Trumpy: That is great depending on which brand of fuses the beancounters buy. Here in Auckland we have MEM for 32 A or less which have unfortunately small numbers and same colour coded labels.
I know what you mean with the current stampings which you see on NZI and GEC type fuses.
The Lawson fuses are very well marked with large numbers on the fusebody.

The worst is always when you have some fuses which have been in the truck for a while and the markings have worn off. Then you can't beat the stamped ampere values.

4mm² is now protected with 25 A MCB.


The product of rotation, excitation and flux produces electricty.
