I need more power running in my girlfriends poolhouse which has a microwave, refrigerator, tv, laptop, blowdryer, ceiling fan and a few lights and I'm attempting to add quite a bit more electronics to.
It currently runs the whole thing on a single 20amp breaker with room for 1 more breaker in the box which I'm assuming is a 30amp box.
I have close to zero experience with electricity and what can/will cause damage and I'm looking for the swiftest and easiest way to increase the amperage in the house.
Can I just simply swap the 20amp breaker for a 30amp or should I put in a pair of 15amp breakers? And if I have to add a breaker how extensive would the rewiring be?
