DC wiring

[hamcamper]

I have recently been verifying the dc circuits using the notations written in on the dc panel cover. I found that many of the notatons were only partly accurate. For example the lighting for the bedroom slide was noted but the basement lighting wasn't and they are on the same fuse. I have identified all of the loads except one noted as "mp". It is fuse #9 in my panel. Does anyone know what "mp" stands for?

Are you sure that isn't "W" instead of "M" for the water pump?

It is MP but I'll bet that the guy writing it got confused. The next time I go to the camper I'll check. It certainly makes sense. Thanks

You may be right. He may be referring to it as the main pump rather than water pump.
