It is always best to hire a certified electrician to ensure safety.\"}},{\"@type\":\"Question\",\"name\":\"What grounding resistance value is acceptable?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"It depends on the installation. The Spanish REBT does not set a single value: it requires that no exposed part can reach a touch voltage above 24 V in damp locations or 50 V elsewhere, taking into account the residual current device installed. As a reference, ITC-BT-26 recommends not exceeding 15 \\u03a9 in buildings with lightning protection and 37 \\u03a9 in buildings without it. In industrial installations, the target value is calculated at the design stage from the soil resistivity.\"}},{\"@type\":\"Question\",\"name\":\"How is grounding resistance measured?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"With an earth resistance tester, usually by the fall-of-potential method: a current is passed between the electrode and an auxiliary rod, and the voltage is measured with a second rod placed at about two thirds (62%) of that distance. The measurement is taken with the electrode disconnected from the installation at the main earthing terminal or, if it cannot be disconnected, with a clamp meter. At Procainsa we measure, record and document the values at every inspection.\"}}]}<\/script>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Grounding, also known as earthing, is one of the most important elements of any electrical installation.
