Testing the Ground Circuit 2018 Electrical Safety Testing
Ground Continuity Testing Ground Continuity testing is the same concept as Ground Bond testing. Youre simply checking for a continuous path on a ground circuit. However there are key differences between these two tests. Purpose Method A DC low current test to check circuit resistance. Similar concept to the Ground Bond testing.

resistance or lack of continuity in equipment grounding systems. These accidents could have been prevented by proper testing and maintenance of grounding systems. Grounding systems typically include the following: 1. equipment grounding conductors the conductors used to connect the metal frames or enclosures of electrical equipment to the

Testing Equipment for mining eod blasting explosives
Bore Hole Deviation Surveying. Basic electronic gear such as continuity testers and multimeters assist the explosives tech with electrical circuit analysis. It is important to have a continuity check before blasting. It is also wise to check the resistance on the wire to ensure all blasting caps are hooked up properly.

MSHA Program Policy Manual Volume IV
When a record of testing is required by the standard MSHA intends that the test results be recorded in resistance value in ohms. 56/57.12042 Track Bonding This standard requires that both rails shall be bonded or welded at every joint and rails shall be crossbonded at least every 200 feet if the track serves as a return trolley circuit.
Ground Continuity Polarization and Ground Bond Tests
Ground Continuity Test. The purpose of a ground continuity test is to verify that all conductive parts of a product that are exposed to user contact are connected to the power line ground the green wire . The theory is that if an insulation failure occurs that connects power line voltage to an exposed part and a user then comes into
