- 10-18 Ga. Wire
- 30 Amp circuit breaker

-
Application: This kit suits wiring an aftermarket electric fan on hot rods, street rods and performance builds where a temperature-controlled fan switch is needed, using a 3/8 inch NPT sensor to trigger the fan automatically off coolant temperature.
-
Size/Spec Context: The 30 amp circuit breaker suits lighter draw single fan setups compared to the 40 amp version in the range, so it's a better match for smaller electric fans with lower current draw rather than larger high-output units.
-
Construction Note: Kit includes 10-18 gauge wire, crimp terminals and hardware, with easy to follow instructions for a complete DIY install without needing to source additional wiring components separately.
-
Fitment Note: Universal kit suiting most single electric fan setups. The temperature switch turns the fan on at 185°F and off at 170°F, a fixed threshold rather than adjustable, so confirm this switching point suits your cooling system before ordering.
-
What to Pair With: Commonly paired with a single electric fan rated within the 30 amp circuit breaker's capacity. Check your fan's current draw first; higher draw fans should use the 40 amp version instead.
-
Practical Buyer Tip: Check your fan's rated amp draw before choosing between this 30 amp kit and the 40 amp version, since running a fan close to or over the breaker rating will cause nuisance tripping.
