Recommended Circuit Breaker for 12v Power on 7-Way

Question

Question:

Would i use this same Pollak 30amp breaker for power to the 7 way connector? I see that you recommend it for the black 12V 10gauge input wire to the brake controller. Part number PK54530

The Pollak Circuit Breaker - Cycling/Automatic Reset - 30 Amp - Straight Mount Bracket # PK54530 is the correct fit for a brake controller but we recommend the 40 amp # 9510 for the 12v Power wire to your 7-way. We do recommend using # 10-1-1 wire you referenced.
