A 40 amp breaker on a trailer wiring 7-way circuit would be for the 12 volt accessory circuit which goes to the 1:00 pin of the 7-way on the tow vehicle. For a breaker we have the # 9510 and for 10 gauge wire part # 10-1-1 sold by the foot. Worth mentioning is that this circuit doesn't have to be active unless you have like a battery to charge or interior lights to power. Otherwise it can be left off as it doesn't need to be there for other circuits to work.
