Page 56: Wire Sizing
Load lead resistance is also an important factor relating to the CV stability of the instrument when remote sensing capacitive loads. If high capacitance loads are expected, you should not use wire gauges heavier than 12 to 14 AWG for long runs of load lead. Keysight N6700C Series User's Guide... - Page 57 4. “x” indicates wire is not rated for the maximum output current of the power module. 5.
