Does it matter when you turn the battery disconnect switch back to the "ON" position in this scenario?
The only way "arcing" can occur when you plug a cable into any source feed is if there's a load on the circuit - i.e. no load = no arc. Ideally everything should be off when you plug in but in reality there often is some load, so if your battery is connected to the converter the latter will instantly see the former as a load and depending on it's state of charge may present a significant load on the system. Ideally you would turn your battery disconnect switch to the off position before plugging in to avoid this but I'd bet most don't. Since I use an EMS to protect the trailer's electrical system this entire point is moot as the EMS won't pass on power to the trailer anyway until it's predetermined delay time, either 15" or 136", has passed.
