Table C: Conductors Sized (AWG) for 10% Voltage Drop

Use 10% voltage drop chart  for any “non-critical” applications: windlass, cabin lights, etc…

10% Voltage Drop at 12 Volts

10% Voltage Drop at 24 Volts

10% Voltage Drop at 32 Volts

ABYC Recommends…
“Conductors used for panelboard or switchboard main feeders, bilge blowers, electronic equipment, navigation lights, and other circuits where voltage drop must be kept to a minimum, shall be sized for a voltage drop not to exceed three percent. Conductors used for lighting, other than navigation lights, and other circuits where voltage drop is not critical, shall be sized for a voltage drop not to exceed 10 percent.” 11.16.1.2.7.
