Where 60,309 fits
Why 60,309 is special
The colour of the connector encodes the voltage — blue for 230 V, red for 400 V — so a mismatch is visible before it is attempted.

6 × 10,000 + 3 × 100 + 9 × 1 = 60,309. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
