transfer switch

This transfer switch has been pre-wired to automatically change the primary source of AC current from shore power to generator or inverter power when activated. It has a 50-amp double pole switch that includes (2) 120V legs, which can provide 240V service if needed. To prevent electrical interruptions, the time delay circuit board allows the alternate power source to stabilize before a transfer occurs. Additionally, since the switch only accepts one active source, it protects your electrical system from dangerous backfeed that can damage your equipment.

The metal case has cord knockouts for the various connections.


Automatic Transfer Switch Installation

The switch wires to your shore power input and generator or inverter input. Both inputs are wired to the AC panel.

This transfer switch automatically changes from shore power to generator power when needed. Protects your electrical system from AC power backfeed.

by:

The transfer switch was a direct replacement for a unit in a 2020 travel trailer. To my way of thinking that was premature for the age of the unit. Unit was easily replaced and was functioning well when the trailer was recently sold.




by:

The Transfer-Switch was easy to install and a very well made switch. American Made products or the only thing I want to purchase .




by:

etrailer customer service is AMAZING. I had a few questions & concerns about the product & they were very knowledgeable & made sure I understood everything.




by:

Since the previous transfer switch was discontinued I purchased this item. Had to trouble shoot just how connections went however not very difficult. Unit has been in for one year with no issues.




by:

Direct replacement for the factory unit. Has worked great.




by:

Good product and fast delivery. Our RV was down without it, we are now back up and running.




by:

So far it’s been working as expected, it fits in the same spot as the other one. No humming no sounds other than when power goes out and you hear a loud thump.




by:

Overnight delivery got here before noon! Great service.




by:

The product was a perfect replacement match and it was delivered very quickly




by:

We’ve ordered from etrailer before and the speed of their shipping is unbeatable so we knew who to order from when our generator transfer switch failed from a power surge. They came through for us once again when we were in a bind! I paid for 2 day shipping and it was packaged and shipped immediately and delivered exactly when they estimated. It was packaged well and functions exactly the way it should. Very pleased!! Thank you




by:

Order was on time,install was simple.




by:

The agent on the phone who helped me was amazing




by:

The transfer relay was as represented and works great. I didn’t have generator power or shore power. In fact 240v was in my outlets in half of the motor home. My original transfer relay had one relay for each leg. This one has only two, and works great. It took a little to be sure I was wiring it correctly. I also replaced the box to plug in my shore cord. A previous owner had pulled away with the cable still attached. I used a “drill to fit” plastic box from a big box store. I have both generator and shore power.




by:

Works without any issues!




by:

Great seller product arrived very quic kly




by:

PD52 was ordered on 7/12/20 via internet. No contact with me till I called on Thursday, 7/16 and order was found. Paid for 4-6 day delivery. Shipping e-mail received on 7/17/20 via UPS. Package delivered on 7/21/20. Item was inside larger cardboard box with no package material, bouncing around and box was damaged. Hoping electronic components are OK. To be installed on 7/24/20 by electrician. Very first problem with e-trailer after many orders.




by:

why are the nipples stamped the wrong way,, shows that no one is doing quality check , very poor.




by:

Perfect fit for what we needed!




by:

Exact same thing I had in my xlr perfect replacement and the new one works great




by:

From orderi time to actual receipt of item was beyond spectacular!




by:

Just what I needed and fast. Service as promised. Great Job as always.




by:

I bought a nice, but used diesel motorhome. The years old PD52 stopped working after two camping trips. The past owners had left a new auto switch, a different, more expensive, brand. I installed it and I wasn't happy with it.

I ordered a PD52, two day delivery. It came on schedule and I am back up and running again!

I am going to order another since the price is right! Good to have a spare although I am confident it will be a long while before I need it.

I like this product!




by:

Arrived in good condition and was easy to instal. When tested after installing worked perfectly.




by:

Excellent service - timely - will order again




by:

Greg was Outstanding from the first call to delivery and the follow up. He promised two days and it was here. You have my business from now on

  • Installation of Progressive Dynamics Transfer Switch in 2016 Newmar Dutch Star RV
    I think that your level of comfort in doing this repair lies with your level of comfort in doing electrical work-if you'd be comfortable doing electrical work at your home, this probably isn't a huge undertaking. If it's not something that would normally be in your wheelhouse, I would rely on someone with electrical experience to complete this installation. With that being said, if you do decide to take this one on, I also recommend disconnecting any batteries as well- those are going...

  • Transfer Switch for 2021 Keystone Montana 3781RL that Can Use 50 and 30 Amp Power
    Yes, since the Progressive Dynamics Transfer Switch # PD52 is 120 and 240 volt compatible this will work fine with 30 amp as well as 50 amp. This 50 Amp transfer switch will allow you to hook up the 30 Amp shore power to the HOT 1 connection in the box. When you decide to upgrade to a 50 amp setup, you will use HOT 1 and HOT 2.

  • Can Progressive Dynamics Transfer Switch PD52 Have Shore Power on Normally Closed Connection
    I reached out to Progressive Dynamics to find out if you could have the shore power on the Normally Closed position for the Progressive Dynamics Transfer Switch # PD52, and this is what I was told via our tech contact: "I think there is confusion here; the PD52 uses two normally open contactors not a single relay with normally closed contacts in the inactive position as with the PD51. Second, the RV transfer switches are designed as "Generator Priority" that means that whenever AC voltage...

    The Progressive Dynamics Transfer Switch - Metal Case - 50 Amp - 120V/240V # PD52 (Alternatively PD52V) and the PD52DCS/PD52DCSV are both part of the PD52 series but there are some differences.

  • Does Using PD52 Require Additional Transfer Switch When Adding Inverter
    The PD1600 series contains an internal transfer switch. We do not recommend feeding the output of the inverter back to the MAIN AC distribution panel due to the fact that a fully operational panel would quickly drain the battery and the converter/charger must be isolated from the inverter when the inverter is operating. We recommend feeding the inverter AC IN from the main panel and feeding the AC OUT to a sub panel for multiple branch circuits or directly to a single branch circuit.

  • Transfer Switch For A 50 Amp RV To A 30 Amp Shore Service
    Realistically you should be using a 50A transfer switch like the: -Progressive Dynamics Transfer Switch # PD52. As using a 30A transfer switch would leave one leg of your panel unhooked, which isn't ideal. However, with that being said you can use your 30A transfer switch with a 50A service.

  • Replacement For Motorhome Automatic Transfer Switch
    According to Progressive Dynamics, their ATS # PD52DCS would work perfectly fine for you as long as the existing input is 120/240V and the incoming amperage doesn't exceed 50A. As long as the incoming power matches and the capacity of your existing ATS isn't greater than 50A, this will work for you.

  • Recommended 50 Amp Transfer Switch To Accommodate Shore Power, Generator Power, And Inverter Power
    A transfer switch is only going to have two receptacles to accept power from so you wouldn't be able to connect all of your systems together, but I do have a solution for you. You would need to use a 50 amp transfer switch like the Progressive Dynamics Transfer Switch # PD52 and connect it to your shore power and generator power to the trailer, giving you an automatic switch over between the two sources, as you can see in the attached video below. With that installed you can then wire...

  • Is Any Manual Switching Needed with Mighty-Mini Distribution Panel?
    I assume that by “Van Power” you mean 12 volt charging via the 12 volt accessory and charging line coming from the van to the battery. As a matter of physics, the battery will see the 12-volt source with the highest voltage. So, if your van 12-volt line is supplying 13 volts and your solar panels are supplying 12.8 volts, then you will have charging at 13 volts without any intervention from the panel. When connected to shore or generator power the converter will charge the battery. When...

  • Can I Use 50 Amp Transfer Switch With 30 Amp RV Setup
    It is possible to use a 50 Amp transfer switch with a 30 amp setup since you plan on upgrading in the future however, the Furrion Transfer 50 Amp Switch is made for 50 Amp setups. I recommend to use Progressive Dynamics 50 Amp Transfer Switch part # PD52. This 50 Amp transfer switch will allow you to hook up the 30 Amp shore power to the HOT 1 connection in the box. When you decide to upgrade to a 50 amp setup, you will use HOT 1 and HOT 2.

  • Can I Use the Progressive Dynamics PD52 to Replace a Furrion F50ATS
    Yes. You could use the Progressive Dynamics # PD52 to replace your Furrion # F50ATS; they're both rated for 50amps so they are compatible. The Furrion does provide a bit of extra protection against power surges though with it's 125/250v supply, so I do prefer that choice when possible.
