At SafePower Safety Systems all of our technicians specialize in the testing of 3 Phase equipment. The minimum requirement for testing 3 phase equipment is to have an earth leakage test carried out using a 3 phase leakage tester. The allowable earth leakage current limit for 3 phase equipment is 5mA. Once the earth leakage test is done an earth continuity and insulation resistance test can be done. Upon completion our technicians will then tag the 3 phase appliance with a durable tag and then record the results.
