I have a low voltage panel box (modle # lv4 ) in a used 5th. i have bought. The question i have is the lable on the box says.---- this unit MUST NOT be occupied with the master shut-off switch in the "OFF" position. Dose that mean the main master swith on the beaker pannle or what. Plus on the the bottom left hand side of the box there is a pull nob that looks like it would be a on & off swith. When the trailer is park should it be on or not. In other words if you could tell me what box is for (which i no my fuses are behind the cover plate.) & what is for ,or what setting that nob needs to be in when the trailer is park or in use.
I hope that this is going t the right place & i all so hope that you can help me out.
Thanks a lot for your time. Confused in texas Steve
