One thing you will need is a ground buss for your 12 volt circuits. The pd4045 gives you a positive wire for each fuse but doesn't give you a negative so you need to run that. I ran a 2 wire cord for each circuit and hooked up the ground all in one place rather than running single wire grounds to the frame all over the place. I used a label machine and labeled each wire as i went. With all the connections in the same place and labeled any issues will be easy to sort 10 years from now or 40 years when i am gone and the next owner has to deal with it.

Forgot about the ground part. I was disappointed they didn't build that in. I used this.

Is that also an inline fuse there? And the grounding terminal has to be grounded to the frame?

Great idea! If somebody had done that earlier in my Boler's life, I wouldn't be in such a pickle over this wiring!!

If you're talking about the silver part, I wired all the 12v hot wires through a 6 pin round trailer connector. Unconventional, and I'm sure technically not to code, but it makes it easy to move the converter for access.

Nothing 12v is grounded to the frame, just one from the 120v side between the converter and frame.

Overwhelmed by electrical system

The PD 4045 is great but the instructions suck. I found this diagram online and it helped sort out some of my confusion. I don't have the sound system etc that's on this drawing but you can use it to get a clearer idea of what you're trying to design. There' s a few pics on my Boler thread of my install. When I was finished I plugged it in and turned on each breaker and installed each fuse one at a time. The trailer didn't burst into flames and everything worked. No one was more surprised than me. If you have any questions I'll offer what limited knowledge I have.

As for the inverter question in cars. My Dodge Journey has a built in inverter and outlet. I'm not sure how many watts it'll deliver but it has run the bosses curling iron in an emergency.

Forgot to mention. In the Boler I installed a 12 volt cigarette lighter type plug that has a double USB outlet and one of my 120 plugs has two USB outlets. My logic was that I will now be able to charge a phone or any USB powered item from either battery power or shore power.

My last two Ford Flexes (Flexii?) have had a 100w 120vAC plug next to a 12vDC (120 watt or 10 amp) accessory outlet.

If you only have a battery for a source of power (like a car or trailer) and you need AC, then you need an inverter (which inverts 12vDC to 120vAC)

If you only have a battery for a source of power (like a car or trailer) and you need DC then an accessory outlet is all you need. You're just passing along the battery's 12v.

If you only have one of the two types of outlets (it doesn't matter which) they make different devices that will plug into one and output the other. That is, a device that plugs into 12vDV and output 120vAC and a different device that plugs into 120vAC and outputs 12vDC.

The code requires that you label /identify the line and neutral conductors at a panel . Brady and T&B make self adhering wire markers for this purpose . Marking your DC wire with + & - and circuit #s makes trouble shooting in the future much easier . Plus making an accurate ,legible panel circuit directory is a code requirement and again a big help in the future . Counting on remembering exactly how you wired something several years down the road does not usually work

Anyhoo... at least my brain is only sizzling a bit now. Not fried like it was earlier.

I wish I could hire someone to walk through it with me. I used to have an appliance repair guy who would let me peek over his shoulder and would explain everything as he worked.

Morgyn,

I will be working on installing the same power center this weekend in my Casita. The following is a collection of links and guides that I have read through in preparation for this project. I started with almost zero knowledge and now feel somewhat confident.

The 3 images posted by "absolutsnwbrdr" are awesome (the image Raff posted is one of them). I would suggest ignoring all posts by Esteban (Steve) because he is VERY confused throughout the thread. Although the responses others provide to straighten him out are fairly educational.

Toyota offers a 400W AC outlet option in the rear of the pickup beds; it will run a small cooler, tools, - and a small air compressor (yay!)

I'm almost posi9tive your car has a 12V charger set up for your cell Morgyn. Are you saying it has regular 110/120V plugs like in your house? That would be very unusual. Trust me, you do NOT need an inverter!

By the way, there are two versions of the 4045, on that has 3 places for breakers, one that has 4. You will use the one to the left for you main breaker (maybe 30 amp), the middle one and one to the right 15 amp for 110V and 12V stuff (one for each). If you have 4 breakers, you could use the extra one for a big 110V power load, like a microwave or AC (or both, just can't run them together usually). I have 4 positions with mine, and have AC and a microwave, and still have a spare circuit breaker space.

Best of luck to ya!

Frank

Overwhelmed by electrical system

Apparently it has both. I've never used or really noticed the 12v socket as the other is my life saver!

And it looks like my car needs a good dusting now.

And thanks, folks, for all the help! It should be fun to see how it all turns out! Looking forward to the challenge now.
