Surge Protectors

[Field Trip]

We expect delivery of our 05 DSDP 4009 in early February . One issue I am concerned about is surge protection. For our current coach we have a Surgeguard for 30 amps, but will need something more than this for the 50 amp coach.

The coach is coming with a cord reel. Can we mount the fixed 50 amp Surgeguard on the coach easily with easy access ? Or would it be better to get the portable unit? The cost for each is the same except the installation .

Will the 50 amp surgeprotector work with a site that only has 30 amp service ?

I have a 50 amp service and cord reel and I installed a 50 amp Surge Guard on my RV. I installed the hardwired unit in the compartment so it's out of the way and out of the weather. All you really have to do is pull a couple of feet of cord off the cord reel (you won't miss it) and splice the unit in between the cord reel and the transfer switch. The 50 amp Surgeguard works fine on either 30 or 50 amp shore power but you can't make a 30 amp SurgeGuard work on a 50 amp service. It's a great unit and in addition to surge protection it also offers low voltage protection, which is just as important.

Field Trip , Congratulations on getting a Newmar Dutch Star, I have a 50 amp surge protector from EMS works great, and yes it will work fine on 30 amp service.
I have my in the electrical service bay where the 50 amp cord is contained. Ed

Cruzer & Ed,
Thanks for the information!
Ed, Where did you find the "EMS"? Does it have the same features as the the Surge Guard Model?

Here are full details on the 50 amp hardwired EMS system. Available at RVupgrades.com

Features:

High low voltage protection: Whenever source power falls below 104 Volts, or rise above 132 volts the EMS automatically shut down power to the RV. Once the AC source rises above 104-volts, or below the 132-volt level the time delay indicator flashes for the preset time and then automatically restores power to RV.

Time delay for A/C Compressor: Whenever source power is interrupted by the source or the EMS, due to a fault condition the built in time delay is activated. There are two settings on the EMS; one is 136 seconds, and the other is 15 seconds. Consult you Air conditioner manual to see if it has a time delay built in if so use the 15-second delay if not use the 136-second delay

5 Mode surge protection: This feature provides full surge protection L-N, L-N, L-G, L-G, L-L, and N-G. Total Joule rating is 3640, response time of <1 nano second.

Surge Indicator: If ever a power surge damages the surge protector circuit within the EMS L-N, or L-G The digital display error code will read E-10. This is your indication that it needs to be replaced.

Reverse polarity protection: If source power is a reverse polarity condition, the EMS will not allow power to the RV and the error code will read E1.

Open neutral protection: If the source has an open neutral condition the display will not light, and will not allow power to the RV.

Open ground protection: If source power has an open ground condition the EMS will read an error code of E2 and will not allow power to the RV.

AC Frequency Protection: If source power frequency deviants +/- 9 hertz from 60 cycles per second the EMS will shut down source power, and indicate an E7 or E8 error code on the digital display.

Accidental 220V protection: If 220 volts is detected when plugging into source power the EMS will not allow power to the RV. If this condition occurs while power is applied to the RV, the EMS shuts off power instantly. The display will read the voltage and the appropriate error code.

Remote information panel: Scrolls continuously all of the power source information, voltage, current, frequency, error codes, and previous errors. Each reading is displayed for 2 seconds

Previous error code: This feature tells the user why the EMS previously interrupted power to the RV. This is only displayed if an error actually occurs and goes away when power is disconnected to the EMS.

Bypass switch: This switch is located on the remote panel, and allows the user to bypass the computer circuit in the EMS in the event of computer failure, thus allowing source power into the RV. This does not disable the surge protection portion of the EMS.

Modular design Replacement parts are designed for simple plug and play, making repairs extremely user friendly.

Microprocessor controlled: The computer, and remote display are driven by state of the art microprocessors that are programmed with software to drive the entire EMS. Should ever this software be changed EMS, owners can receive a free upgrade processor with the return of the old

Field Trip,

Hopefully you didn't rush out and buy the new 50 Amp SurgeGuard right awy. You folks probably don't know this, but you can trade up to the 50 amp unit for a small fee plus shipping. This is vary resonable way to get the unit that will best suit your needs.Technology Research Company Incorporated(800-780-4324)

If you are handy, I would get the protable unit and make up the connections inside the electrical compartment. If you decide to change coaches again, you can take your Surge Guard with you. Why keep buying protection when you already have it. These units will last you a life time.

And, if your in the market for a Surge Guard, don't waste your time and money buying the 30 amp unit, if there is a possiblity that you going to move up to a newer coach with a 50 amp service, go for the 50 AMP unit now. The 50 AMP unit will work perfectly on 30 AMPS.
