I think screw terminals is something Progressive Dynamics should have provided along with a proper fuse block. Might add a dollar to the price. Raz

Brady makes a book of self adhesive terminal /wire markers . The book has markers for 0 thru 15, +/- , Pos / Neg and A to Z. They also make books with
1 thru 45 & 46 thru 90 . Brady also make a printer for making wire markers that uses a special tape to adhere the wire markers to the wires insulation. There are also wire markers that are printed on nylon rings which slip over the wires insulation and then shrink. I have wired systems that had over 2000 control wires and the numbering / marking of the wires is critical. On larger equipment which have multiple voltage systems IE 480v -380v- 230v- 120v- 48v-12v & 5 VDC we used color coded wires for each system along with numbering.
Relying on your memory does not work .

Terminal Strips

Terminal strips aren't used in the construction of new RV's or most other motor vehicles simply because they are too labor intensive for mass production applications. However they have been extensively in industrial applications for years.

But, as long as we are looking for references, what is the documentation/reference declaring what is best practice for RV repairs/referbishing. Again, if there are any real (not hypothetical) examples of the risks in using terminal strips when rewiring RV' 12 VDC systems, let us all in on that news.

As an electrical engineering tech, (EET) I have used terminal strips often. I see no better alternative for a dry location.

Jameson@PD said

not to wire 7 prong 12V charger line to panel breaker 12V line. He told me to wire it directly to the battery (+) with an in-line fuse. I didn't ask why, I just "obeyed".

Also I need to know something, maybe one of you know...if a car say an F150 comes prewired with a 7 prong, do you need an ISOLATOR off the alternator?
So say you're parked and didn't unhook the trailer-to-car wiring. On the drive to destination it charged the trailer battery...but now as the trailer discharges will this drain the car's engine battery if you don't have an isolator IF the car came with the 7 prong set-up?

Also you can buy block terminals with fused or fitted plexi tops, or just screw a plexi top over it, or what I did finally is put them vertically and tucked away under a ply-box so nobody'd get zapped (I had to move the entire arrangement from front to back of trailer, arg). The ground block terminal is not hot but the 12V ones are. Here's one for $1.95

Also don't forget to wire a hot 120 from a 15A breaker to the vertical 120 bar to power the converter.

Block Terminal Debate

In my case with 8 switches (24 wires, an extra 16) plus 2 lights, vent, 2 chargers not on switches (5 more), I'd have had an entire unrecognizable ball of spaghetti without block terminals. I think they're more secure in that you can really squeeze down the attachments and if something doesn't work 99% of the time it's due to a bad connection at the block terminal. It's also more organized, logical.
The PD of course like all panels uses block terminals for the 120s.

My Nissan with factory wiring disconnects the charge line when the key is off. The only way I know that was that I measured the appropriated pins. There was nothing in any of the literature. Best way to be sure on the car in question would be to measure. Raz

My truck came with a factory 7 pin receptacle . The charge line from the tow vehicle has power at all times. I wish the truck came with an isolation relay.
I unplug the trailer when we are camped to prevent the TV battery from accidental discharge.

Verdict: Unplug or get isolator

Thanks for the tips.

The conclusion I would draw is that it varies by manufacturer. Infact it may vary by vehicle. Nissan used to leave the 12 volt outlets hot with key off. Mid 2012 they changed the design. Take a measurement first. Raz

- 120v system was just like wiring a house... Will explain with pics if needed but the DC side of things was most confusing for us!
I'm about to hook up mine but wouldn't mind a clearer picture of the AC side, if possible? I think I'm clear on the DC side of things but confused when you say that 'the power wire to the converter was hooked up in the wrong location". I've been searching for a decent pic of a hooked up PD but have yet to really see one. Thanks so much!

RE: PD-4045/4065

You need to attach the black power wire for the Converter to it's own circuit breaker, that you install, not to the main power breaker, which is back-fed to power the AC distribution buss.

Thanks Bob.. So I just give the converter it's own breaker and remove it from the lower "12V HOT" bussbar on the lower right. Do you mind if I ask you another couple questions as I'm not a pro with this kind of stuff?

If so... 1) What is that bus bar labelled "12V HOT" 4 pin bussbar on the lower right that the converter is currently installed into for???? Should I run 20 or 15 amp breaker boxes to the converter, and will a 20 or 15 amp box suffice for two electrical plug in sockets and one that's under the cabinet that services the fridge?

2) With this PD unit, Do I have to run another line back to the battery for charging it or does the DC line coming into the PD unit also charge the battery when applicable??

Thanks Bob, these might be dumb questions but I want to play it safe.

I was told by PD that the extra bussbar was to meet CSA standards. I use it as the 120vac ground buss point.


The 12 VDC line from the battery to the PD-4045 will also charge the battery


I found a 10 amp breaker for the converter, but they are hard to find. 15a or 20a for the outlets is fine and a 30A main breaker is OK as long as you provide a 30 amp shore power cord and plug.
