Circuit Breaker Needed for splicing a 30a RV with a Multiplus?

[carson805]

Hey folks,

I'm excited to be apart of this forum. I am planning out an install of a Victron Multiplus 24/3000 in my 30a toy hauler, and I'm currently working through the design on splicing my 30a connection to route up to the Multi and back to the AC distribution panel. Now if I splice the wires coming in directly from shore power, there won't be a breaker between shore power and the Multiplus AC IN. Is this an issue? I'm considering getting an additional 2 breakers to mount in a box near the Mutiplus, that will break the hot legs coming in and out of the multi for added safety, but I haven't seen a lot of people even mention this concern. Seems like most people just splice directly and run the 6/3 directly to the Multiplus AC IN.

I appreciate the help!

Definitely have a breaker for ac input and ac out.

I like midnite big baby enclosures and midnite MNEAC fully rated breakers of appropriate amperage.

Sounds good! Wow yeah the MidNite enclosures look awesome. All I could find were those waterproof PVC ones for small enclosures.

Your shore power cord would already be connected to a breaker on the campground pedestal.

You can certainly add a second breaker in the circuit that is inside the camper.

Yes, there's no need to double up on the breaker. You're lucky if a campground pedestal breaker will pass 20 amps on a good day anyways. Most of them are so worn out they'll trip if you sneeze in their direction.

I keep my multiplus limited to about 23-24 amps when we're at the campgrounds. Saves my 30a plugs and keeps me from having to reset their breakers. Before my MPII I've replaced the plug end on my surge suppressor twice due to crap campground outlets.

I've found that 23 amps is plenty even if I have the AC or the electric heat running. The batteries will assist when the water heater cycles, but they quickly recharge afterwards.
