sixwheeledbeast Posted December 5, 2013 Share Posted December 5, 2013 They had noted they'd wired panel 0V to earth to correct?That's a bad idea, this would cause an earth loop. Also just think how noisy that mains earth would be from EMF and RFI. Link to comment Share on other sites More sharing options...
MrHappy Posted December 5, 2013 Share Posted December 5, 2013 Must have been advanced for its time I suppose, IIRC around 25yrs ago stuff started to get modern features of time & date logs & lcd displays ect... TS700 came after CPA6's TS2000 & TS800 ect... & was the low end "networker" panel Mr Veritas God Link to comment Share on other sites More sharing options...
datadiffusion Posted December 5, 2013 Share Posted December 5, 2013 Yes it had a networker style 4 digit rkp That's a bad idea, this would cause an earth loop.Also just think how noisy that mains earth would be from EMF and RFI. Thought that myself. Under maint until this year. So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment Share on other sites More sharing options...
arfur mo Posted December 5, 2013 Share Posted December 5, 2013 That's a bad idea, this would cause an earth loop.Also just think how noisy that mains earth would be from EMF and RFI. that would be one if my concerns, but more so if you got a earth elsewhere, it could bypass a zone or tamper. old school was to make 8 - 10 turns coil around a small screwdriver to act as a 'choke' in each core at the panel. IIRC around 25yrs ago stuff started to get modern features of time & date logs & lcd displays ect...TS700 came after CPA6's TS2000 & TS800 ect... & was the low end "networker" panel Cricky - you will be romancing about lace wiring and t&b frames next ) If you think education is difficult, try being stupid!!!!
