This is what I sent in a private message.
Sorry for the confusion. My buddy has a power cord from his generator to a 30 amp receptacle in the storage compartment where his factory installed power cord is located.
You need the same thing.
Here is what I would do. If you in fact do have a L530R on your generator, buy a L5-30Plug at Home Depot, along with some #10-3 SO wire. Enough to get from the generator compartment to the place where the RV plug is located.
Also buy a 30 amp RV receptacle. If you get the water tight one, it will work. If you get the type that goes into a deep metal box, it will also work, get the deepest box that it will fit into. The guy in Home Depot electrical department can show you both.
Use a 2 screw cable connector to keep the wire from removing itself from the metal box (either system). And I installed a 2 screw connector into each hole I drilled though my storage compartment walls, to protect the wire from the sharp sheet metal. You will need at least one by the generator compartment, unless you have a plan that will keep the wire safe. Use 3/4" 2 screw connectors. they have a lock ring, and 2 screws to clamp the wire in place, so it will not vibrate, or wear through the insulation.
Wire the L5-30plug to the 3 wire SO cord, green to Green, white to silver screw, black to brass screw. At the storage compartment end, the green goes to the round part of the receptacle, the next position going clockwise looking at the face of the plug is white wire (from the side with the screws, it will be green on top, white to the right, black to the left) From the front, after the receptacle is in place, it will be green on top, white on the right, black on the left. (yes it reverses, depending on the side you are looking at.)
Now with the new plug and SO wire in place, new receptacle in the back, you can use a 50 to 30 amp adapter to plug in the 50 amp cord to the new 30 amp receptalce that is hooked up to the generator all the time. No need for a transfer switch.
Fred.
