Here is the scenario: My battery will be located up front under the forward seat in a 15' Grumman Scrambler (Jon). I have a transom mount trolling motor and will be using a male/female trolling motor plug to disconnect it for removal. The trolling motor and plug both have 10 ga. wire. From what I have read, I will need to use 6 ga. wire to run from the battery, through a 60 amp circuit breaker and back to the trolling motor plug. The distance from the battery to the trolling motor plug is about 11 feet. My question is; how do you properly splice 6 ga. wire onto 10 ga. wire?
