Hi, my project box is a large tin cookie box. I need to bring in +15V,
-15V, and GND lines from my external bipolar power supply. (I was
thinking I would have a separate bolt for the chassis ground, which
would go off to a big ground bus bar near my workbench.) For the three
lines from the power supply, I am wondering what would be the best (but
economical) choice for a power connector to mount into the side of the
project box. Something that sounded appealing was the spring speaker
terminal clips I see on Amazon, but the downside there is they only come
in pairs of two or four, rather than three, and they are color coded
red/black which does not quite make sense here. I am inclined to leave
the wires on the power supply itself bare on the end, rather than
attaching some specialty connector to those.

 
There's always the old benchtop standard of binding posts.

 
I second this.

Screw pillars with 4mm banana sockets in the centre.  Available in a
wide range of colours, rated to 500v and 10 amps.  Easy to fit, easy to
plug-up and easy to see what you are doing so you don't make silly (and
expensive) mistakes.

Use matching colour-coded wires and plugs, so there is even less chance
of a screw-up.
