i have a TT system in a sorry state. please could you advise on these points
1.The earth cpc has snapped off the earth rod and is to short to reconnect Its is 2.5 csa. What is the required csa for the main earth 10mm or 16mm
2. there does not appear any bonding on the incoming gas supply. What is the csa required 6mm?
3. the consumer unit is rewireable type protected by a RCD (no sure if its 100ma) between consumer unit and incoming supply. 1 lighting circuit, 2 ring, 1 heating and electric cooker
what protection do i need in the new CU and should i remove the old RCD before the CU
thanks in advance
