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!

You should post to the vehicle sub.

But NO you don't NEED one but should have one on both sides of the splice. RVs should have a breaker protecting the inbound power but they don't always. There's a 30a breaker on the campground pedestal so that protects everything downstream as long as its all wired up with the proper gauge wire and everything. Doesn't matter if spliced into both as only 30A can come in.

This means you're trusting the CG pedestal breaker to work... ya know that one that's flipped by everyone all the time to turn on/off power. Spend the $100 or whatever on a subpanel box with dual 30a breakers so it comes in from shore to both breakers.

Yes you need a breaker on the OUT
