I have a panel constructed using finger safe terminals. Trouble shooting using a voltmeter with 600 volt fusing and insulated probes(typical fluke DMM), or solenoid tester is going to be performed. The following is also known:
1. The Arc Flash hazard by analysis and NFPA 70E tables is 0.
2. The voltage in the panel is a maximum of 120VAC.
3. The control panel is constructed with all finger safe items.
4. If components in the control panel are to be replaced lock out tag out procedures require the control panel to be de-energized.
NFPA 70E Table 130.2 has the prohibited approach boundary at ?avoid contact? for conductive objects unless the user is insulated. OSHA has a similar approach distance.
I have asked a couple of manufactures and they keep confusing the answer with arc flash PPE.
Questions:
1. Can testing be done without wearing voltage rated gloves?
2. What if the same conditions except the voltage is greater than 300volts ar voltage rated gloves required?
3. If the answer to the first question is no, why would you use finger safe terminals?
4. If the answer to the second is no, why do they make finger safe terminals for 600 volt devices?
