Sorry I meant this for the other Brian! ~Reg
From: Reginald Henry Sent: Monday, July 20, 2009 4:03 PM To: 'Brian O'Connell'; 'IEEE EMC & SAFETY PSTC' Subject: RE: Normal power supply Sweden & Norway Brian, I do prescreening for FCC here in my lab @ Vicon Industries Inc. I have a GTEM Cell and use TILE software. to do Conducted and Radiated Emissions. Our product line is made up of unintentional radiators and is primary CCTV and ITE equipment. The answer that you will get from most in terms of overall numbers I would think would be product dependent. As you know different products will use different tests to meet the FCC ,CE standard or IEC standards. The outside lab that I use to verify FCC pretty much has kept the cost the flat. Other then the requirement by the FCC to extend Radiate E testing out to the fifth harmonic of the fastest clk in the product which lead to a charge for additional man hours and hence the increase in cost.

Most point to similar reasons - the compromises that Tesla had to make to get a win over Edison, etc. From: [email protected] [mailto:[email protected]]On Behalf Of 'Rich Nute' Sent: Monday, July 20, 2009 11:23 AM To: 'Ralph McDiarmid'; 'IEEE EMC & SAFETY PSTC' Subject: RE: Normal power supply Sweden & Norway Hi Ralph: Is it common throughout Europe to distribute 3-phase power to single-family homes? Well, yes. I'm not sure of England. If so, why are single-family and duplex residences in North America supplied with 120/240V single-phase? I'm sorry, but I can't answer the question.
