On my 2011 H33 there was a breaker for shore power in the cockpit lazarette. This breaker can trip on a ground fault or overload. Check there to see if it t r ipped.
By the sometime in the 90's Catalina started to put their shore power two-pole breaker on a box that covers the back side of the shore power inlet on their boats. Smart move, given that ABYC "suggests" that there be less than 10 feet between the wiring entry and the breaker. This functionally reduces that distance to less than a foot. I would guess that Hunter did something like this as well. So do check out the area immediately behind the cord inlet.
Our '88 model boat had the factory shore power breaker on the AC panel inside the cabin, and this turned out to be about a foot or two too far.... So I copied the scheme from Catalina and and built a little frp cover box on the back side of the shore power receptacle and put a new Blue Seas breaker there. Just a little detail, but one that would "flunk" a survey otherwise.
Part of boat ownership is getting your head into all (!) of the spaces on your boat to know what's there. While it's true that you can hire this done @ $100/hour, it's best to personally know these details first hand.
Happy exploring!

ps: we have been sailing a similar sized boat for 20 years -- perfect size. Not too big to single hand and roomy enough for a couple to spend a month's vacation on.
