The Solenoid uses 24 AWG wires. Why do you have to use 16 AWG wires to run from the relay to the solenoid.
Thank You

FIRST always trys to be conservative with the wire sizes. It is much better to be safe than sorry and not every team has someone who can calculate the safe wire size.

Imagine that your robot is “impacted” by a falling 20 year old Russian satellite (since FIRST robots never bang into each other): the wires to your solenoid are severed and shorted. With thin 24 AWG wires, the wire gets hot and fuses, perhaps at several places along the length, causing potential fire hazard. With thick 16 AWG wire, before the wire heats up, the circuit breaker cuts out and disconnects the circuit. :slight_smile:
