I would argue that you won't see much of a difference. The breakers take WAY longer to trip and that is only when they heat up due to prolonged excessive current. If you're consistently tripping the breakers, I'd say you have bigger problems to worry about than a resetting Jag.

As always, keeping the battery fully charged will minimize the chance of a Jaguar browning out at ~6V. I'm confident that teams using the advanced CAN features also know to check for the "I just powered on" flag so they can reconfigure the reset Jag.
