hello ericmark,
thank you for your reply
In a standard domestic install is there a limit on how many lighting curcuits you can have say 3 Living room,kitchen and bathroom,then upstairs and loft for example, Is this a common sense thing aslong as the cu has the room.
Can you explain in simple terms the difference between the types of earthing
I think my house is a tn-c-s the two phases come into the house there is a large fuse housing,then the meter and tails to the cu, for the phase conductor.
there's a black box on the neutral conductor and I'd say about 16mm aswell which is going to the cu, and the neutral goes meter,cu
the other earthing is going to gas meter, aswell as the hot & cold water pipes plus heating pipes it terminates at the bath, there was nothing on the shower or the pipes for toilet or the kitchen sink pipes so I've done it already should this be tested, I've used 10mm the same as what is already been used also I used copper connectors to the straps it looks
neater rather than rapping it around the screw.
thanks tt
