New Berks have Surge Protection?

Just thought id ask. In the 'electrical bay' of my 19 34QS, it just has the Magnum Inverter and the silver box that says "MODEL PD52 automatic transfer relay switch" which is from the company Progressive Dynamics ... The 50A shore power cord runs into this silver relay box and then power comes out of the relay box into the rest of the RV.



So Id assume since incoming 50A power from the shore power cord goes into this silver box first, that it would have surge protection. But if I look up the PD52 transfer relay switch, I go to the website and the description is:



"Automatically senses generator power and prevents two power sources from entering the AC Distribution Panel at the same time"



So, any suggestions? Maybe this coach has a main surge protector somewhere else? Maybe I should buy one of the inline ones that goes to the "plug/prong" end of the shore power cord? Do these RVs even need surge protection? I had a base model Fleetwood pace arrow diesel that came with one.

I do not think you have surge protection. The silver box is just a auto transfer switch.

The surge protection would be something you would have to add. No the XL doesn't have it from factory

Boy Iím glad I noticed this. Most people probably wouldnít even think about this. Kinda sucks. Should be standard. What else doesnít come on these that Iím overlooking or assuming is there, but isnít?

Surge protectors are just that, they protect against power surges. You may never see a power surge unless lightening strikes near by.

A PI-EMS (Electrical Management System) protects from much more which you will more likely see in a campground. Reverse polarity, low voltage, missing neutral and open ground are the most common problems found in campgrounds. If power is lost the EMS has a built-in adjustable time delay to allow the power to become stable. Below is the error code list and what the EMS is checking for and if any are found the EMS will not let power through to the RV.

Error Code Chart
E-0 Normal Condition
E-1 Reverse Polarity Condition (hot and neutral wires reversed)
E-2 Open Ground (ground wire is not connected)
E-3 Line 1 Voltage High (Line voltage above 132)
E-4 Line 1 Voltage Low (Line voltage below 104 volts)
E-5 Line 2 Voltage High (Line voltage above 132) - not available on 30 Amp models.
E-6 Line 2 Voltage Low (Line voltage below 104 volts) - not available on 30 Amp models.
E-7 Line Frequency High (Line frequency above 69 cycles per second)
E-8 Line Frequency Low (Line frequency below 51 cycles per second)
E-9 Data Link Down - Remote Display models only.
E-10 Replace Surge Protector Module
NOTE: If the EMS cuts the power to the RV it will show a PE code following the E code. This denotes the previous error or why the EMS shut down. Example: The EMS cuts power for low voltage on Line 1, and then the power is restored. The Error Code reads E0, but the PE code reads PE4 which tells the user low voltage was the reason for the EMS previously cutting power. This PE error code will be deleted when power is disconnected from the EMS.

Bet your expensive gaming computer or flat screen TV didn't come with one either.

There's a lot of things that these units don't come with..... XM radio's installed, decent sound systems, TPMS, hose reels, proper windshield shades and on and on..... They could but then they would cost more.
