name: Established Wiring Standards
- On a cable with with both ribbed & smooth insulation, the smooth side
should always be connected to the voltage source. This voltage source
could be the red terminal on a battery/amplifier, or the 'hot' in an
AC power circuit.
- Motherboard power cable colors should be reinforced where possible:
- red: five-volts-regulated
- purple: unswitched-five-volts-regulated
- yellow: twelve-volts-regulated
- black: common
- blue: negative-twelve-volts-regulated
- orange: three-point-three-volts-regulated
- green: power-request-circuit
- "Crimp on connectors should never be used on solid core wire or on wire
that has been tinned."
- "Ferrite chokes electronically isolate signal cables from the power
network. Using a high-quality shielded [data] cable with built-in or
external Ferrite chokes to help reduce interference on the line from
any motors and to help reduce the effects of electro-static discharge."
- "Daisy chaining is one way of powering several different [modules].
Multiple [modules] are wired together, with each unit being powered by the
one before it in the chain. It is common to daisy chain the power
terminals on [...] motor and servo controllers. In a haphazardly-wired
setup, daisy chaining can cause many issues. If one connection in the
middle of the chain comes loose, the power to the remaining [modules]
will drop. [...] A better way to design a power distribution network is to
use a power distribution terminal [...]. With this method, if any one
controller disconnects, the other controllers will continue working."
