In the UK, the wires are colour coded so brown is live and blue neutral so I follow the convention. Probably not necessary though!<div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/64999.aspxWed, 21 Nov 2007 09:47:12 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:64999PhilLondon0https://archivedforum.beoworld.org:443/forums/thread/64999.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=13&PostID=64999<p>me again... in the US, the power is 110 volts, 220 in europe, this could cause a big problem if they are not multi voltage.</p><p>p.</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/64998.aspxWed, 21 Nov 2007 09:45:41 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:64998PhilLondon0https://archivedforum.beoworld.org:443/forums/thread/64998.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=13&PostID=64998<p>There is no polarity on AC cables...
