In our guide to the best 30 AMP RV breaker box options, we’ll discover which breaker box you should buy.

Breaker boxes are there to house essential safety components. If you have an electrical surge in your RV, safety components will stop your power supply. It plays a vital part in your RV setup and will protect against fires and electric shocks.

We will explore what you should look out for when buying an RV breaker box, and we will also show you the top 8 on the market.

First, let’s examine some signs that your RV breaker box needs replaced.

Signs you need to replace your RV breaker box

One of the most obvious signs that the breaker box in your RV needs replaced is when it keeps tripping.

Suppose you find that your electricity is continually going out and you need to trip the box. In that case, it is probably time to replace the breaker box.

You can check some things before you go out and replace the box itself.

You can check your electrical appliances to ensure that they are not faulty. Also, do not overload the system by using too many appliances at once. Overloading the system can cause the breaker box to trip.

If you aren’t overloading your system and your appliances are all working OK, it is probably time to invest in a new breaker box for your motorhome.

Things to consider when buying an RV breaker box

You should consider a few things before you buy a breaker box for your RV.

AMP Size

In this guide, we will look specifically at 30 AMP breaker boxers.

Usually, for RVs and motorhomes, breaker boxes come in either 30 AMP or 50 AMP.

30 AMP boxes are usually found in smaller RVs, while you will find 50 AMP systems in larger motorhomes. The main difference is that a 50 AMP system can handle more electrical appliances at one time. In a 30 AMP setup, you will probably need to turn certain items off to use other appliances.

When you are looking for a breaker box, buy one that matches your electrical system.

Installation

Installing a breaker box in your RV can be tricky.

The actual installation process should be pretty similar for each breaker box, but some will be easier than others. If you do not feel particularly confident fitting it or have little experience working with electrics, get a professional to install it for you.

A common problem with RV breaker boxes is the knockout holes. These can be tricky depending on the box’s material and how sturdy it is. You may need additional tools to do this job, so keep that in mind when buying a breaker box for your motorhome.

Cost

The cost does not just apply to breaker boxes. You should always weigh up the cost of anything you buy for your RV.

Breaker boxes are not massively expensive; however, some will cost more than others.

Decide what your budget is and how much you can spend. Remember, a breaker box is an essential safety item. It does not pay to skimp on the price if paying slightly more money will get you a better and safer product.

Durability

It is doubtful that you will want to replace the breaker box shortly after purchasing it. Looking for a durable and high-quality breaker box is recommended.

Some breaker boxes can be a bit flimsy, and the door hinges can break if they are not constructed with durability in mind. Buying a breaker box with a waterproof cover and strong hinges will ensure that it lasts for years before you need to replace it.
