• Flat braided ground cable has lower impedance than typical round
wires and hence makes a better ground connection.
• Never assume that connections are good until you check them with
an ohmmeter. Should be <1# for short runs or <5# for long runs.
• Ground cables inside test dummies should be braided type with a 12-
gage equivalent size.
• Ground cables from a test article or vehicle to the SLICE Stack should
be braided strap type with a 15-gage equivalent size.
• The cable from a test article or vehicle to the Earth connection
should be large enough to create an a low impedance connection
given the distance between Earth connection and test vehicle. 8 to
12
• If braided c able is not available, any ground wire is better than none!
