![]() ![]() In this scenario, if the circuits are de-energized before the fuse box, then a worker can open the fuse panel without fear of arc flash (upon verification of de-energization, that is). So, for example, any high voltage fuse box where live circuits are exposed if the panel door is opened. The idea with arc flash risk potential is that the electrical components do not have protective covers or that a worker could be exposed to electrical hazards during regular operation. ![]() That is to say, we all pick up something powered – a vacuum, touching the power button on a computer monitor – typically powered by the standard 120 volts in North America or the 240 volts in Europe. We need to assume that there is an exposed conductor. On Or Near Electrically-Powered Equipment Let’s look at the answers to these questions briefly. What is the meaning of on or near electrically-powered equipment?.Looking at the above, we now have some definitions we need to address. The defining factor is an electrically-powered circuit. That is to say that I hope you don’t go near a live circuit. Works on or near electrically-powered equipment where that power is above 50 volts, and there is a risk of exposure to live components.īut wait, doesn’t that mean anyone near a regular 120-volt circuit needs arc flash training? No, your normal 120-volt circuit at home or office isn’t something you work on live.Who Needs Arc Flash Training?Īll electricians should require arc flash training as a component of their license certification.įurthermore, arc flash training is appropriate for anyone who: The training typically lasts around a day at the end, the professional should be competent in determining arc flash risk potential and complete an arc flash risk assessment. Accidental touches and brushes against energized componentsĪrc flash training is specialized training to help professionals understand the dangers and precautions regarding the arc flash event. ![]()
