The basic rule is to size the conductors to meet the load, then size the overcurrent disconnect to protect the wiring. I thought you were concerned about drawing too many amps from your batteries :-) Yes, as others are suggesting, an overcurrent disconnect should be placed inline between the battery and the Sevcon. It should be rated at about 125% of the ampacity of that conductor. You can apparently program a maximum current limit with the Sevcon ... I don't have Sevcon programming skills yet but I may need to get there. Sudden current increases occur when the controller is set to maintain a particular rpm in the presence of a sudden increase in rotational resistance like a crab pot. Also, my concern is that both house and propulsion power is supplied by the same bus so the Sevcon can only protect and limit propulsion current.
