If the 48 VDC facility is equipped with a circuit breaker rated at 60 A (-48 VDC), then the
grounding cable must be minimum 10 AWG, or as permitted by the local code. If the 48
VDC facility is equipped with a circuit breaker rated more than 60 A (-48 VDC) up to 100
A (-48 VDC), then the grounding cable must be minimum 8 AWG, or as permitted by the
local code.
NOTE: Additional grounding is provided to an AC-powered router when you
plug its power supplies into grounded AC power receptacles.
