Going to two breakers - how to wire?

Check my post on providing safe power. I'm still working on it but it should help you.

So that was really helpful. We are upgrading to the new inlet and I will make sure to get some 10 ga wire to run to the breaker box. I am also thinking that it will be best to just replace the breaker box and breaker as well.

The old breaker box looks different from the new ones (I am looking at the image 003eBreakerBox1.jpg). Looks like on the new ones you run the positive to one spot and then click in the breakers. Then you use those "ground bars" for the negative and the ground, again looking at that jpeg. Does this sound right?

It looks like that photo has two 15s and a 20 in it. Is that right?

So what I need.

1. 10 ga wire to run from inlet.

2. New breaker box - "load center?" Where can I get the size that is show in that photo. So many I see online are huge ones for a house.

3. Two of the ground bar kits.

4. Two of the 15 amp breakers (are there different size of 15 or is that good?).

Related question - for my outlets and switches I should be buying the 15 amp versions correct?

Thanks everyone! This board makes the overwhelmed feeling go away.

I use this box from Home Depot:



It is Square D, QO and will run 4 circuits with tandem or twin breakers. The common bar and ground bar are already installed.

Here it is with the cover on:



You can use one 15 amp breaker for your original lighting and a few plug-ins, the next 15 amp circuit for more outlets and the final 20 amp circuit runs kitchen appliances and possibly an outside receptacle.

My boxes don't have a "main" breaker and only control the trailer circuits. The main is on the shore power line.

Thanks for the reply as always!

Is this the right box? www.homedepot.com/p/Square-D-by-Schneider-Electric-QO-60-Amp-2-Space-4-Circuit-Outdoor-Main-Lugs-Load-Center-with-Non-Metallic-Enclosure-and-Neutral-QO24L60NRNM/100174454#.UdGR2DvVB8F

Are these the right breakers if I am going to do two 15 amp? www.homedepot.com/p/Square-D-by-Schneider-Electric-QO-15-Amp-Single-Pole-Circuit-Breaker-QO115CP/100061177#.UdGR2DvVB8F

Will this inlet work or do I need to get one of the ones from VTS (would prefer to save the 40 bucks)? www.homedepot.com/p/Reliance-Controls-20-Amp-Power-Inlet-Kit-PK20/202216489#.UdGf1jvVB8E

I have a couple more questions before I head out and start spending. 


In the attached image, the wire being pointed at by the green arrow seems really thick. Is that what the 10 ga wire looks like or is that something else? 

I am not sure what the wire is that is pointed to by the red arrow? Is that to provide power to the 20 am breaker? Is that something I can buy premade or do I need to create? If premade, what is it called? If I need to make, how can I do so?

Thanks!

If you want to save money on the inlet. Buy the 30 amp cord and cut the end that is female off and strip the wires back. See the photo in the providing safe power thread that shows the clean box like this one and a junction box beside it. The junction box is for the connection between the cord and the solid copper 10gauge that goes into the box and to the lugs. Then use something like this to get the cord outside.

Vikx could tell you for sure as thats where I got the above picture but it looks like that is about 8gauge by the green arrow. The red arrow is a jumper to the second lug for the other breaker, it should be 12 gauge min because thats a 20amp circuit.

If you can avoid it, don't tie the neutral (white) and the ground (bare) together on the same buss bar as shown in the hand sketch in a prior post. Keep them separate its much safer.
