OK. had a question yesterday about main earth regs. Please can some1 answer something for me as i am a little confused. Stacked consumer units main one and economy 7 one below it. The main one has a 16mm main earth (all ok so far) the cheap rate one has NO main earth (two storage heaters and an immersion on it, 3 circuits total) I really do not understand why this is not earthed, please someone explain (and yes i am only 4 months into my career as a sparky so very green at the moment)
