	As above. I undestand that for Class 2 compliance, the power adapter requires a max power output availability of less than 100W. What about class 1? Is there a class 3 as well? Thanks.

	My understanding is that the Classes for CE marking of mains powered electrical goods have nothing to do with power. They are levels of electrical protection. e.g All accessible metal is earthed. Or the unit is double insulated etc. I am not going to quote specifics. You MUST check up on this. Del __________________ health warning: These posts may contain traces of nut.

	You must first define what part of the world you are referring to. In the US, there are UL classifications that are not the same as those listed above and indeed they have power limitations. http://ulstandardsinfonet.ul.com/scopes/scopes.asp?fn=1310.html __________________ All I every really wanted to be, was...

	Yeh...when will people condescend to tell us where they are? Our answers are only as good as the information provided... Hey I just looked at the link...your standards are just as confusing as ours . Don't ya love it when it states... 'this standard does not this'...and 'not that', makes me want to shout I want to know WTF it does cover...not what it doesn't!

	I am on your side FOR SURE!! Del... In an upper discussion regarding concrete slabs, I had to watch the pounds, concepts used, and make a Wild assed guess that he was in the US. We should not have to do this. If we have someone with an electrical problem on your side of the pond, and I know that, I will keep my mouth shut and let you answer it. This is kind of like having a question asked in English, and expecting the response in Swahili. It does not work... Bill And it is so simple if these people just let us know where they are... Bill
