| Far be it from me to tread on the toes of the music buffs, but 99.99% of what is proposed or postulated in this sector is complete bloody nonsense. Where I have to deal with systems that might be likened to the issues surrounding hi-fi and earthing, then avoidance of earth coupling and socket outlets supplied via electrical seperation transformers (with or without voltage stabilisation cores) would seem slightly safer and successful route for the OP than risking his client binning the RCD. Try a look for such companies as Claude Lyons for examples and take a read through Regulation Group 413. For those into TT'ing sockets in PME areas (ie virtually everywhere) - spend an hour with a low amperage reading clamp meter - try it around anything that looks metal and see what's really flowing in the ground - and into your earth rod. I was standing outside a building with the BOD a little while back and we clamped the handrail of a recently installed disabled ramp and also the adjoining scaffolding for facade repairs - we were seeing levels of earth leakage that would have us in 543.7 territory Regards OMS And another topic link that was prior to "me too". https://www2.theiet.org/forums/forum/messageview.cfm?catid=205&threadid=35309&messageid=292718 Apologies. I couldn't find a way to put this at the start of my reply Kelly, but the above are topics that relate to the widespread presence of diverted neutral currents in handrails and scaffolding. And pretty much everything else! Regards BOD |
