Wire Gauge Considerations
Background
Before connecting the output terminals to a
load, the wire gauge of the cables should be
considered.
It is essential that the current capacity of the
load cables is adequate. The rating of the cables
must equal or exceed the maximum current
rated output of the instrument.
