Steve W-O Posted January 22, 2011 Share Posted January 22, 2011 Firstly, the "arrestor" in the BT socket offers no protection against a strike, it offers a discharge path for static build up, often found when lightening is nearby. If there was a strike on the cables, the results, like all lightening strikes would be unpredictable, but it would certainly fry the "arrestor" and on to fry anything else connected to the cable.The PC speaker output would not go above 50V, and if it was the line out to amplified speakers, it would only be 600mV.If it was strung between two buildings, then it would be the same as a wire washing line, but less worry if it was temporary cable that was unplugged when not in use.There is a huge difference between what an electrician would "like" an sign not off for fear of any come-backs, and what in fact doesn't comply with the regs.It is common (bad) practice for aerial installers to throw the TV aerial feeder over the roof and drop it down to the entry points, this is also an outside conductor.

Hamish Posted January 22, 2011 Share Posted January 22, 2011 I am afraid I cant agree with you Andy. If you consider intruder alarms, fire alarms, door entry system and similar type systems they do not have isolation transformers fitted when wired into different buildings.Perhaps once you have studied your Regs you can provide a definitive answer Quote Link to comment Share on other sites More sharing options...

Hamish Posted January 22, 2011 Share Posted January 22, 2011 Unfortunately Eric that is not the answer to the original question, an alternative option, but not the answer. I have got to assume your brain has the sawdust cyano syndrome at the moment Quote Link to comment Share on other sites More sharing options...

Terence Lynock Posted February 4, 2011 Share Posted February 4, 2011 You can get cordless headphones with a range of about 20 metres now, as for rules and regs in France we were told once you go over the white line and enter the traffic flow at le Arc de Triumph your on your own, your insurance company wont cover you so you settle up out of your own pocket. The traffic flow around that erstwhile monument is something to be seen to believe it, suicidal students on mopeds, psychotic grannies in massive Mercedes, and for gods sake dont try moving over to the left if your driving a right hand drive vehicle otherwise it will take you two hours to dig all the Citroens out of your tire treads....
