Step Potential / Touch Potential

Section 5.0 of the Australian / New Zealand Standards Wiring Rules require earthing installations to limit Earth Potential Rise under transient and fault conditions to provide safe step and touch potential, in accordance with that standard.

For High Voltage installations, at clause 7.6.2 AS / NZS 3000 specifies compliance with AS 2067. We can test the soil, provide an EPR report, prepare an earth design which allows for compliance with the Standard, and then on completion, provide injection tests to demonstrate compliance. Once complete, we can issue a Certificate of Earth Compliance for that design.
