How To Install a 30 Amp Service on an Enclosed Cargo Trailer

Question

Question:

I have a 7x16 cargo trailer that I use as an onsite service trailer. I currently run a extention cord to a power strip for inside power. I want to set this up to run off a 30amp shore line or connect to a 3500W inverter generator mounted on the trailer tongue if I should not be near shore power remote. I plan on installing 4-5 interior outlets with one dedicated to run a portable 10K BTU AC, then the others would be for laptop, power tool chargers, maybe a mini fridge or other small electrical items and one 4ft LED shop light. Could you guide or suggest the best route to make this happen.

Yes, in order to set your trailer up for use with shore power you will first need an AC distribution panel. For this, I recommend a Progressive Dynamics Series AC Distribution Panel. In order to bring power into the panel you will also need a power inlet, the Epicord 30 Amp Twist Lock Power Inlet part # 277-000138 and a shore power cord, the Furrion RV Power Cord with Handle part # F3OR36SBOEM.

If you want to sometimes power the trailer with a generator you will also need an adapter for the above shore power cord, the Power Grip Generator Adapter for RV Power Cord part # CAM55272. The rest of the outlets, wires, and conduit can be obtained from your local home improvement store.

The first thing you'll need is a power inlet to receive power from the shore power pedestal. You'll most likely only need 30amp service since you're in an enclosed trailer so I recommend the Hughes Autoformers Safe View Smart Power Inlet…

Yes, you can use a 3000w Inverter with transfer switch like part #34275013 and still use it with your Progressive Dynamics Mighty Mini AC/DC Panel and Converter/Smart Charger #PD4060K. The inverter is going to require you to have two separate AC bus…

The best way to power the interior lights in your trailer is with its own independent battery. You will not want to use the breakaway battery. The breakaway battery is only designed to operate the breakaway and will drain extremely quickly,…

You would not be able to charge your battery through the wiring on your 4-way trailer connector. Since your truck has a 7-way connector, you could maintain the power to the battery but not charge it. To begin, you would need to cut off your 4-way…

I was able to find a photo of a Lance travel trailer with the large 3 tank cover that you referenced. If your setup looks like the one in the photo, from what I can tell, you should be able to install the Stromberg Carlson Trailer Tray #CC-255, but…

There's quite a bit of available room under the bunk adapter #CC-255 to allow you access to the propane tanks. I attached a couple pictures that shows how much room you'd have. I also attached a review video link for more info on it as well!

Hey Robert, yes you can use the SoftStartup part #SSR64FR with your Hughes surge protector. This will prevent the large surge needed to fire up AC units but it does not have surge protection built into it.
