Hi realise i have a major earthing /bonding probs in my house built circa early 60s Have partially installed new ring mains . (all to code ) and installed new lighting circuit (to code). Will be working on replacing rest of new ring main soon ....(old remaining/spur radial system on sep circuit ).
I understand i need to cross bond all copper pipework and need to bridge sections of plastic pipework with 6mm earthwire etc to provide continuous earth back to new consumer unit etc, and will do this now . Regs or publications of exp of regs states that radiators and pipework must be earthed /bonded .
QUESTION 1 does this mean earth strapped copper pipe connected to rad by compression joint must also be joined with earth strap on radiator too .or can it be assumed that compression joint joining pipe to rad provides sufficient clean path re earth bonding ??
QUESTION2. What do i do if i cant get behind bath panel to crossbond bath taps to bath(old enamelled cast iron type) to pipework (elec shower over bath etc, ) I can however cross bond pipes linking w.basin copper pipes to bath copper pipes (and know its cont copper pipe between the two ) is this ok ???
QUESTION3 I have just installed a few lights that are double insulated and hence need no earth and have wired these into existing (earthed)lighting circuit via junction boxes with new switches etc..Is this likely to cause probs? or is it against the regs to mix earthed lighting and unearthed lighting(double insulated )within same lighting circuit.
your comments would be appreciated at the earliest poss opportunity.
