KPA500 fusing and cable-colouring

Hi all,

Started assembling the KPA500 last night and noticed the use of fuses for the AC supply.

Unlike other parts of the world, we don't have individually fused socket outlets or plugs so I'll
incorporate a small enclosure with flush fuse holders.

Now, do I need to fuse both phase and neutral, and what are the correct colours? In New Zealand and
Australia (and most of the Commonwealth) we use red for phase and black for neutral.

Cheers,

Paul

Hi Paul,

The AC input module in the KPA500 has a place for you to put the fuses
- no need to build your own ;)

Actually, in Australia, the official colours are now brown for active (phase) and blue for neutral. It used to be red and black many years ago, but then they standardised on these new colours for some reason.

Fuses are in the KPA500 nifty power receptacle on the back panel. I run
my KPA500 on 120VAC and it works just fine. Admittedly it's on a
separate circuit, I had a couple of them run into the shack during a
remodel about 10 years ago, but it runs fine on 120V.

And here in what began as a colonial empire, once electricity had been
invented, the author of the NEC decreed green for safety ground [earth],
white for neutral not to be confused with green, black for "hot" [phase,
active, "the donttouchit wire"] if it's 120 VAC RMS, and red if it's 240
VAC RMS. Orange, yellow, violet, gray, and mauve apparently are not
used anywhere in the world?
