Ytter,
As a rule you should use FINE tin plated stranded wire. It should be
sheathed with either fiberglass or metal braiding. It can be ordered from an
industrial wire supply house. It cost more than other type wire, but the
overall cost difference at the job level is minimal. Just as importantly,
you should consider the mode of most common failure of wiring. That is
corrosion at the wire terminal interface. To avoid the moisture migration
cause, you should use crimp terminals without insulation and a crimping tool
that provides enough pressure that the terminal to wire connection actually
welds. Then shrink tubing is applied and after the terminal is installed the
entire connection should be painted with a rubber compound. This also can be
ordered from the industrial supplier or directly from OMC.
