R615       *Use appropriately sized wire. All circuits shall be wired with appropriately sized insulated copper wire (SIGNAL LEVEL cables do not have to be copper):

Table 12‑8: Wire sizing requirements

Application

Minimum Wire Size

12V Main Battery Power

18 AWG

(19 SWG or 1 mm²)

Motor Power (unless otherwise listed)

11-20A fuse protected circuit

Motor Power - TETRIX MAX 12V DC Motors, REV Robotics Core Hex (REV-14-1300)

22 AWG

(22 SWG or 0.5 mm²)

PWM / Servo

LEDs (5V / 12V)

≤10A fuse protected circuit

SIGNAL LEVEL circuits (i.e., circuits which draw ≤1A continuous and have a source incapable of delivering >1A, including but not limited to: I2C, DIO, Analog, encoder and RS485 connections)

28 AWG

(29 SWG or .08 mm²)

Integrated wires originally attached to legal COTS devices or wires included/sold by the manufacturer are considered part of the device and by default legal. Such wires are exempt from this rule.

In order to show compliance with these rules, teams should use wire with clearly labeled sizes if possible. If unlabeled wiring is used, teams should be prepared to demonstrate that the wire used meets the requirements of this rule (e.g., wire samples and evidence that they are the required size).

Combining multiple smaller wires in parallel cannot be used to create an equivalent larger wire which meets minimum wire cross section requirements.
