I am building a camper out of an all aluminum cargo trailer. I got a apiele 32A 3 position 8 terminal rotary selector switch. I want to switch between my Bluetti AC 300 solar generator and shore power. The Bluetti has a 30A plug to hook a camper into it. I was wanting to wire the other end of a 30 amp cord to the switch. And have the shore power on the trailer hooked to the switch. So I can select either source to my power distribution panel. Some videos iv watched have said to use jumper wires. Some didn’t. One guy combined all the grounds together. With a wire nut. I could use some clarification

I think I am following what you are doing but on the off chance we have a miscommunication or are not on the same page I would need more info to provide info. You can contact me through my website with pix drawings and the like and if I can get a clear picture of what you are doing I may be able to help.

i want to put a rotary switch in my motorhome, so i can alternate between the 230v mains hook up and a 230v 30amp hook up from a battery power bank made for motorhomes, 2 alternative feeds into the switch with one common feed going back to the original fuse box, so i can have mains electric from the power bank when wild camping, am i right in thinking just wire up the rotary switch but have the 2 sides used as feeds feeding the common i have seen 32amp rotary switches which is what i am going to use, enjoyed your video thx for taking the time to post it regards chris

problem is you are dealing with DC and the high amp rating of most rotary switches is for AC. You will need a specific high volt high amp DC switch and it will be expensive. The consequences of using the wrong switch could be a fire or worse. Thanks for the comment, glad you liked my videos.

I have the same switch, well not same because it only has 2 and yours has 3 which I bought the switch off Amazon and they didn't send me a schematic on how to wire it. I bought it for my lathe because my 110 lathe motor will do forward or reverse and I was on the assumption that switch did. Maybe you can do a video on wiring that switch for forward and reverse? Thanks a bunch I really appreciate the way you explain yourself in videos.

you need to find a wiring diagram for your motor and then test the switch so you know what connects to ehat in any given position

Should be Able to wire all three of the contact gangs on each side in parallel , to triple the contact rating.

excellent point and a nice option to have in a pinch but at that point a higher amp switch with the correct features would make more sense to me as they are not that expensive.

What a mess of jumbled wires using to explain 😂😂

You're not wrong. It wasn't bad until I added the lights and then I didn't realize that the camera angle didn't allow for a clear view of what was going on.
