When installing a new circuit for a pv system it is neccessary to fill in an installation cert. If the earthing can not be verified is it then neccessary to install new 10mm earth wires to gas and water mains or ok to note it on the sheet? Iv'e been replacing earths up to now but this job is sometimes more time taking than the installation itself. What do you guys do?
A long lead can verify if it's within.05 of an ohm but is that good enough?
