I have a 2021 Ventana 4369. I am in the process of planning the upgrading/changing of the electrical system. I wanted to see how the current Southwire Model 40450 RVC switch is wired.

After turning off shore power, I tried to remove the cover to see and photograph the current wiring. Now to the problem.

The cover only has TWO screws holding it on. The other places where I would expect screws and filled with pop rivets. Does anyone know if Newmar closes the cover with pop rivets? Or is there another way to open the switch to check and change the wiring?

In the smaller picture, you can see the single Phillips head screw. The other places that I would expect to see a screw are filled with pop rivets.

Did I miss something?

I just got an answer from Southwire. The cover has two screws at diagonal corners. The pop rivets hold internal parts. I was told to take the screws out, and then give the cover a "good" tug.

Problem solved, I believe.

That's correct. The rivets just hold a set of spring clips. Give it a pull and it will come off.

Yep, I ran into the same thing a few years ago. Unless you look closely it's hard to see there are two removable screws and four rivets, thus it's easy to make the assumption there are six rivets.

Below are three photos:

- The first shows the front side of the transfer switch cover plate, with the two screws removed.

- The second shows the back of the cover plate where you can see the four riveted spring clips.

- The third shows my cover plate after I re-installed it. Note that I used a red marking pen on the head of the two screws, the idea being to make them more obvious to the next person attempting to remove the cover plate.
