If testing for electricity on wooden poles, ladders, or wooden frameworks and the device does not give a reading without a ground wire, a ground wire can be connected to the tester without the need for permission from the shift supervisor. ( ) Error
Error. If testing for electricity on wooden poles, ladders, or wooden frameworks and the device does not give a reading without a ground wire, it is possible to connect a ground wire to the tester, but this must be done with the permission of the person in charge of the work or the person on duty.
Error. Explanation: When testing for voltage, it is necessary to use a voltage tester of appropriate rating and in good condition, and test each phase on both sides of the equipment’s incoming and outgoing lines separately. Before testing for electricity, a test should first be conducted on a live device to confirm that the voltage tester is in good condition. If testing for electricity on wooden poles, ladders, or wooden frameworks and the device does not give a reading without a ground wire, it is possible to connect a ground wire to the tester, but this must be done with the permission of the person in charge on duty.
Error. If testing for electricity on wooden poles, ladders, or frames and the device does not give a reading when not grounded, an earth wire can be connected to the end of the insulating rod of the voltage detector, but this must be done with the permission of the person in charge of operations or the work supervisor.
