What Circuit Breakers Are Compatible With Pollak 7-Circuit Breaker Junction Box?

Question

Question:

Good morning. I am asking about how I know what circuit breakers sizes I need for my tow behind tandem axle trailer? I purchased a pollak 52249 junction box from you recently and need some guidance so I do not order the wrong breakers. I am using a 12 gauge wire I got from my Dad to wire the trailer. I have only basic stop, turn, reverse,marker and electric brakes. Thank you for your time.

You will need to verify the power draw required for the particular circuit you are adding a circuit breaker. Then you be able to select either a 20-Amp # PK54-120, 30-Amp # PK54-130 or 40-Amp # PK54-140 circuit breaker to install in the Junction Box # PK52249.
