didn't hold Word formatting, but you should be able to see the columns.., if not, email me & I'll send you the PDF they sent to me
per Minnkota Tech Service when I was adding a new 80#Terrova I-Pilot:
BOAT RIGGING AND PRODUCT INSTALLATION:
For safety and compliance reasons, we recommend that you follow American Boat and Yacht Council (ABYC) standards when rigging your boat. Altering boat wiring should be completed by a qualified marine technician. The following specifications are for general guidelines only:
CAUTION: These guidelines apply to general rigging to support your Minn Kota Motor. Powering multiple motors or additional electrical devices from the same power circuit may impact the recommended conductor gauge and circuit breaker size. If you are using wire longer than that provided with your unit, follow the conductor gauge and circuit breaker sizing table below. If your total conductor length is more than 50 feet we recommend that you contact a qualified marine technician.
An over-current protection device (circuit breaker or fuse) must be used. Coast Guard requirements dictate that each ungrounded current-carrying conductor must be protected by a manually reset, trip-free circuit breaker or fuse. The type (voltage and current rating) of the fuse or circuit breaker must be sized accordingly to the trolling motor used. The table below gives recommended guidelines for circuit breaker sizing.
*Conductor Gauge and Circuit Breaker Sizing Table
Total Conductor Length (length of all conductors in the total circuit)
Motor Thrust Circuit Breaker 10 feet 20 feet 30 feet 40 feet 50 feet
30# 50 Amp @ 12 VDC 12 AWG 10 AWG 8 AWG 6 AWG 4 AWG
40#, 45# 50 Amp @ 12 VDC 10 AWG 8 AWG 6 AWG 4 AWG 4 AWG
50#, 55# 60 Amp @ 12 VDC 8 AWG 6 AWG 4 AWG 4 AWG 2 AWG
70# 50 Amp @ 24 VDC 10 AWG 10 AWG 8 AWG 8 AWG 6 AWG
80# 60 Amp @ 24 VDC 8 AWG 8 AWG 8 AWG 6 AWG 6 AWG
101# 50 Amp @ 36 VDC 8 AWG 8 AWG 8 AWG 8 AWG 8 AWG
E-Drive 40 Amp @ 48 VDC 10 AWG 10 AWG 8 AWG 6 AWG 6 AWG
*The conductor and circuit breaker sizing table above is only valid for the following assumptions.
1. No more than 3 conductors are bundled together inside of a sheath or conduit outside of engine spaces.
2. Each conductor has 105oC temp rated insulation.
3. No more than 5% voltage drop allowed at full motor power based on published product power requirements.
