Default UL 1449 Certified Surge Protection Devices for RVs

UL 1449 Certified Surge Protection Devices for RVs (SPD)

Just about every article I read about Surge Protection Devices (SPD) states that the device you buy should be certified UL 1449 3rd edition. The effective date of compliance for the 3rd Edition of UL 1449, “Standard for Safety for Surge Protective Devices” was September 29, 2009, so this standard has been in effect for over three years now.

However, I can't find any RV specific surge protection devices that are certified UL 1449. If you've done the research and found any please let me know. Two popular RV or motorhome surge protection devices are:

Technology Research Corp http://www.trci.net/products/surge-guard
and
Progressive Industries http://www.progressiveindustries.net

To check whether the company AND the particular model you have or want to buy go to http://www.UL.com and click on ‘Online Certification Directory’ at the bottom of the page. There are many search options. The UL Category Code for Surge Protection Devices is VZCA.

Progressive Industries does not have any UL 1449 certifications for Surge Protection Devices on the UL website that I can find. I have sent them an email to confirm.

Technology Research Corp has one UL 1449 certification that I can find but I think it is only for this GFCI Single Outlet Adapter . I have sent them an email to find out for sure.

Both of those companies offer products that look to be very good for RV use. Look at the different models to find over and under voltage protection and polarity checking etc. - all very nice features - but, I'm looking for a UL 1449 Certified Surge Protection Device.

UL 1449 Certified Surge Protection Devices have holographic labeling and the letters SPD are required and visible:



Note the letters SPD in the photo.

My search continues. If you are going to install surge protection then you might as well buy one that has the UL 1449 certification and meets that standard. Right now I'm thinking the best protection for your RV electrical system and appliances would be by using more than one protection device. One device that automatically shuts off the power when the voltage is too low or too high, protects against open neutral or open ground, indicates reversed polarity and incorrect wiring. And, add a second UL 1449 Certified Surge Protection Device right at the AC breaker panel.

I'm currently considering adding a UL 1449 Certified Surge Protection Device like one of these for my RV:
Levton Residential Whole House Surge Protector $50 http://www.homedepot.com/p/t/202993881
Eaton Complete Home Surge Protection $69.97 http://www.homedepot.com/p/t/202800798
IG Series Surge Protective Devices http://www.intermatic.com/Products/Surg ... 40RC3.aspx

This post http://www.fiberglassrv.com/forums/f54/ ... post293875 on Fiberglass RV forum was very informative.

Nice comparison chart for the Progressive Industries and Surge Guard units here: http://www.rvupgradestore.com/Articles.asp?ID=279

You'll note that some of the products are "UL Listed" but, as far as I can tell, they are not UL 1449 certified. UL 1449 certification has very specific labeling requirements (see above). The letters SPD will be visible on the holographic label. Go to http://www.UL.com and click on ‘Online Certification Directory’ at the bottom of the page to check what category the device you are interested in is listed under. The UL Category Code for Surge Protection Devices is VZCA.

A quick check of one of Surge Guard's UL listings - E189106 - shows that UL listing is for UL category NMTR:



And a quick check of the Progressive Industries UL listing E213280 shows that UL listing is also for UL category NMTR:



UL category NMTR falls under Miscellaneous Apparatus. It does not include UL 1449 listed Surge Protection Devices.

Quote:
Miscellaneous Apparatus (NMTR)

Products Listed under this category include the following devices: amplifier cards, brakes, circuit monitors, dimmers, autotransformers, clutches, cutout bases for thermal cutouts, resistors, potentiometers, rheostats, power supplies, reactance, resistance, selecting systems, variable-voltage autotransformers, phase converters, enclosed slip rings, indicator interfaces and injection systems.
It's all very interesting and I welcome any comments. Perhaps there is an explanation why UL 1449 Certified Surge Protection Devices for RVs seem to be very hard to find.

Define a surge. And good luck. The word comes without any numbers. Numerous and different anomalies are sold as a 'surge'.

The type of surge that required UL 1449 is completely different from what a Progressive does.

Meanwhile, UL 1449 says nothing about how well a device performs. UL 1449 is only about one completely different device, also called a surge protector, not killing humans. UL is only about human safety. Since the Progressive does something completely different from other devices also called surge protectors, then the Progressive need no UL 1449 testing.

Thanks for replying. It is not clear to me what you mean. If you can elaborate further I'd be grateful and be as technical as you like because I like learning about this stuff.

Note: this White paper from Siemens is good reading for a UL 1449 overview: http://w3.usa.siemens.com/us/interne...Protection.pdf

Plug a device that draws more than 0.5 amps into a USB port. A surge is created. That has no relationship to what a Progressive does. Or what a Monster power strip does. Or what a UPS does. The word 'surge' defines numerous electrical anomalies. A generic term that routinely creates confusion when so many layman make recommendations without basic electrical knowledge. Then a box for only one anomaly gets recommended to magically cure all.

'Surge' is a generic expression that says almost nothing without associated specification numbers.

No relationship exists between a Progressive for an RV, USB port for a computer, and what that White Paper discusses. All do surge protection - from anomalies that are completely different.

UL 1449 applies to one type surge protector. Also has no relationship to surge protection found on a USB port. UL 1449 is only about human safety. Says nothing about effectiveness of any surge protector.

What specifically a device does must be defined, with numbers, long before anyone can make a protector recommendation.

Default Re: UL 1449 Certified Surge Protection Devices for RVs

I'm trying to find a UL 1449 Certified Surge Protection Device for a "whole house" protection of a motorhome.

1. Are there any?
2. Is there a reason why the two most popular RV surge protection brands are not UL 1449 Certified?
3. Is there any reason to not add something like a UL 1449 Certified Levton Residential Whole House Surge Protector $50 http://www.homedepot.com/p/t/202993881 Either by itself or in addition to a power management system that automatically shuts off the power when the voltage is too low or too high, protects against open neutral or open ground, indicates reversed polarity and incorrect wiring etc.

Here's another informative and easy to read article Surge Suppressors: Anatomy Lesson

A post 20 some minutes before your's answers that question. Even the Leviton unit and boxes discussed in Surge Suppressors: Anatomy Lesson are different devices; operate completely different.

Let's say the anomaly is 'open neutral'. The Progressive would detect and respond to that anomaly. The Leviton would not. Surge protection in a computer's USB port would not. Protectors discussed in Surge Suppressors: Anatomy Lesson would completely ignore that anomaly.

Which device, called a surge protector, is required? First answer a relevant question. Which anomaly do you want to avert?

westom - Did you join the forum because of this topic? If so, are you here to promote particular models or particular functions or a particular brand of RV power management devices?

I think this is a very useful topic. People can get very passionate about their product choices and can be quick to defend those choices. I don't want that happening here. The point of this topic is to provide useful information.

If you are going to ascribe particular functions to particular brands please reference model numbers otherwise it is misleading.

For example, this "Progressive" device http://www.progressiveindustries.net/ssp_30.htm



would detect an 'open neutral' anomaly the same way any basic outlet tester plugged into a 30a/15a adapter would. And, neither device would "respond" other than informing you at the time of testing.



The photos in my second post were to reference UL listing numbers. The EMS-HW50C shown in the second post is a multifunction device and is not the same as the SSP30 shown in this post.

This previously referenced chart http://www.rvupgradestore.com/Articles.asp?ID=279 will help sort through the features of The Surge Guard and Progressive Industries units.

Also, westom - do you have a Progressive Industries device in your RV? If so which model and how is it mounted.

This topic: http://www.rv.net/forum/index.cfm/fusea ... m#25485242 indicates that care needs to be taken in choosing the mounting method and location as they can get hot.

UL 1449, the “Standard for Safety for Surge Protective Devices” seems too important to casually ignore. I will try to get official responses re: UL 1449 from both previously referenced companies.

As far as I can tell these three questions have not been answered:

1. Are there any UL 1449 Certified RV surge protection devices?
2. Is there a reason why the two most popular RV surge protection brands are not UL 1449 Certified?
3. Is there any reason to not add something like a UL 1449 Certified Levton Residential Whole House Surge Protector $50 http://www.homedepot.com/p/t/202993881 Either by itself or in addition to a power management system that automatically shuts off the power when the voltage is too low or too high, protects against open neutral or open ground, indicates reversed polarity and incorrect wiring etc.

westom - you quoted question 2 but seem to basing your answer on particular model or multifunction device. I don't see how your answer applies to Progressive Industries model SSP30 for example.

Default Re: UL 1449 Certified Surge Protection Devices for RVs

Both aforementioned RV surge product manufacturing companies responded to my inquiries re: UL 1449 - Standard for Safety for Surge Protective Devices.

Technology Research Corp (Surge-Guard)

Quote:
Thank you for contacting TRC.
The RV products for UL are rated on the website.
The UL 1449 3rd edition is not part of this listing.
No additional information there. The phrase "RV products for UL" doesn't even make sense.

---------------------------------------

Progressive Industries (response from the President of the company)

Quote:
We meet that standard, but not tested.
There may be follow-up answers from both companies. I will post any info I receive.

You have to give the advantage to Progressive Industries.

If a 30A protection device is what you need then the EMS-HW30C hardwired unit feature list is really impressive. http://www.progressiveindustries.net/ems_hw30c.htm

It has a Bypass switch - a feature that its closest sibling doesn't have that might come in useful.

Quote:
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 AC power into the RV. This does not disable the surge protection portion of the EMS; however, all other features are disabled.
Again, here's the comparison chart of both companies RV Surge protection products: http://www.rvupgradestore.com/Articles.asp?ID=279

I was not discussing that device. I was discussing the EMC-PT30: http://www.progressiveindustries.net/ems_pt30c.htm

The SSP-30 is a different device that does not protect from damage by an open neutral or other anomalies.

Again, before making any recommendation, first each anomaly to be averted must be defined.
