Good day to all. I have no knowledge of electrical matters and am just a homeowner who is trying to get a certificate of electrical compliance. I was told that there is an earth problem and the reading was 200 ohm - this would require 6 copper earth spikes to be dropped to get the required 20 ohm. Now that the work has commenced, I have been advised that after 5 spikes the reading is only 160 ohm. The contractor has come back to me and said that his electricians report had initially stated 1200 ohm and he had mistaken it for 200 ohm when he quoted me. The solution is apparently to drop more earth spikes but how many additional required is not known at this stage. I would like to know if this is a common problem and whether it is being dealt with fairly and correctly. Thank you in advance, your advice will be appreciated.
