What I said was UL *listed*.

I don't know what "meets UL 1449" means. It probably means APC claims the UPS meets the UL standard.

I can tell you exactly how it works, APC sells a lot of UPS's, since they specialize in this, and to claim it meets a UL spec when it does not, opens the company up to major lawsuits should there be an incident.

In fact, it would be pretty stupid for a major UPS company to falsly advertise their product, meaning, they claim the product meets a UL spec when in fact it does not and they never tested it for that. APC would have been out of business a long time ago.

They may test for part of the spec. It would be real hard for an user to tell if part of the test was missing. They may also fully comply. Why don't they just get surge listing?

APC is a major brand. A lot of people in newsgroups recommend them. I still want a UL1449 listing and wouldn't buy APC unless it had one.

Because high ratings are easy to get, I would actually rather get a high rated plug-in suppressor and plug a UPS into it. I would then rather the UPS had no surge rating. (UPSs with high ratings are harder to find than plug-in suppressors.)

I went to the ACE Hardware (a reputable store) website and typed in 'surge protector' and they sell a protector made by Power Squid. I went to their website and they do not even mention being UL listed (nor meets a UL spec), etc. for any of their products.

You said you do not trust a UPS since they do not meet 1449 but in this case, it is the surge protector that makes no mention of meeting a UL standard.

I next went to Lowe's Home Improvement (a reputable store) website and typed in surge protector. They sell protectors made by Prime. I went to Prime's website and no mention of UL at all for their surge protection products.

I have heard of Power Squid, not Prime. I would have guessed Squid was listed but wouldn't be surprised if both were not. On the other hand they might be. These days manufacturers, IMHO, are putting out less and less useful information. But there is a lot of crap around.

In addition to UL1449, I want a major brand name for a suppressor. For me, neither of these is (but APC is).


I next looked at Belkin, a reputable company, and found surge protectors that mention UL.

I went to the UL website and looked up their name. UL lists their products but not as 'UL 1449 certified'.

[For UL the magic word is "UL listed".]

Their chart says:

'These products have been tested to verify that transient voltage surges are limited to the maximum applitudes specified by the manufacturer.'

That is, I presume, the 330V for most of the suppressors in the table. 330V is one of the let-through voltage ratings in the UL test. (Equipment typically has an immunity level more like 800V.)

Thanks for the last link in particular. I don't see anything that indicates Belden suppressors aren't UL1449 listed.

The 2 plug-in suppressors I am using are Belden. The boxes indicated UL1449 listing. The suppressors have UL labels. I know that UL is extremely protective of the use of its labels.
