Main Breaker is not turning Off Electricity

[Steph-WO]

I was cleaning my Micro Minnie FLX today and opened the door to the breaker box. I turned off the main breaker just to check it since I had never checked since I bought the trailer almost 3 years ago. To my surprise all the lights worked even with the breaker off. This was the case when connected to shore and not connected. When connected to shore power all the outlets also worked. How is this possible? Welcome ideas. I willl open later today and put my voltmeter of the wires

Assuming that I understand what you are saying… circuit breaker are 110v AC but your lights are 12vdc. So yeah, the lights will continue to work off of your 12v battery even if you turn off the breaker to the TT’s Converter. On your TT, your 12v loads have automotive style fuses, not circuit breakers.
