Earth Continuity Test Maximum Allowable Resistance As3000. As3000 Wiring Standards Earth Continuity Limit The limit for the Earth Continuity Test is (0.1 + R)Ω Put simply this ensures that an 'earth' exists and it is suitable to ensure the fuse/circuit breaker will operate before a piece of 'faulty' equipment becomes 'live', potentially killing somebody.

The resistance of the main earthing conductor, measured between the main earthing terminal/connection or bar and the earth electrode, including the connection to the earth electrode, shall be not more than 0.5 Ohm. The earth continuity test One of the following two tests should be carried out
10A Intelligent Earth Ground Continuity Test Equipment Earth Resistance Current Tester China
4.7.1 Earth continuity tests (a) The main earthing conductor between the main switchboard and the earth electrode is continuous and the resistance of the main earthing conductor does not exceed 0.5 ohms. The earth continuity test shall meet the requirements of AS/NZS 3000 and shall be tested in accordance with the procedures outlined in Clause 4.4 of AS/NZS 3017. Put simply this ensures that an 'earth' exists and it is suitable to ensure the fuse/circuit breaker will operate before a piece of 'faulty' equipment becomes 'live', potentially killing somebody.
Resistance Of Earth Continuity Conductor Test. The principles and methods of earth resistance testing covered in this section apply to lightning arrester installations as well as to other systems that require low resistance ground connections. Where the R value is the resistance of the protective conductor (earth wire) within the supply cable
