Powering Interior Trailer Lights With Generator

Question

Question:

Hi our high school band program has a 24 ft cargo trailer with 7pin connector. We’d like to use a generator with built in 8amp dc inverter to power 12v lights in the trailer interior cargo lights not running or brake lights. Can I just splice a dc plug into the main 12v power and ground cables in 7 pin connector to achieve this?

You may splice your generator into the main 12V power and ground from the trailer's 7 pin connector to power the interior lights if you use an inline fuse like part # SWC9538 and fuse part # C58450-1 between the 7-pin 12V wiring and the generator 12V outlet. I recommend to wire in the power and ground to the Optronics 12V DC power plug part # A-200 to plug into the generator. The Optronics plug is rated for 12 amps. You want to use an inline fuse because if the wiring shorts out it can back feed into the generator and blow a fuse in the generator or fry the wiring in the 12V plug.

If you need a generator I recommend the etrailer.com generator part # 333-0003 that features a 12V plug outlet and an electric remote start. It also has built in safety features to prevent overload. The generator is designed with a 12V 8.3-Amp outlet.

Generators do not typically have a 12 volt power converter, so I recommend using the Battery Charger and Maintainer #CTEK56353 and splicing the connector that would go to the battery terminals into a 7-way connector like #30717. You will connect the…

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…

The only difference between 7-Way Utility and 7-Way RV is the color of the wires. The pin outs are the exact same so either would work just fine with the other. If you check out the picture I attached you'll see that the functions are all the…

Yes, 14 gauge wire seems too small. I would go with 10 or 12 gauge. For 10 gauge you can use #10-1-1 and for 12 gauge use #12-1-1. These wires are sold in increments of 1 foot. So if you needed 20 feet of wire you would enter 20 in the quantity box.…

Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail #AM10130, and a 5.30-12 size tire, like the Kenda K353 #AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire. Keep in mind that these tires do have…
