Raymarine ST1000 Plus & ST2000 Plus manual SeaTalk cabling, Cable length Copper area

Chapter 4: Installing the Tiller Pilot 47

•The tiller pilot requires its own dedicated power supply – it cannot source its power from SeaTalk.

•Power should be taken directly from the boat’s central distribution panel and protected with a 12 A fuse or equivalent circuit breaker.

The following table shows the minimum cable size acceptable for the power supply:

Cable length	Copper area	AWG
Up to 2.5 m (8 ft)	1.5 mm2	16
Up to 4 m (13 ft)	2.5 mm2	14

IMPORTANT:

Correct power cable size is critical for correct autopilot operation. If in doubt, use a heavier gauge cable than specified. A lighter gauge cable might cause a voltage drop between the supply and the autopilot. This will reduce the power at the tiller.
