    A common practice is to install a service disconnect or a main disconnect for a feeder system in the same enclosure compartment as the downstream overcurrent protective devices. This can result in potential safety risks of shock and arc flash. This paper addresses the advantages and disadvantages of isolating a service disconnect for electrical service for industrial and commercial installations f... View full abstract»

    This paper reviews some of the more common electrical safety myths and misconceptions field electrical workers often have. Many of these misconceptions continue in spite of training and education. Some are handed down from worker to worker, similar to tribal knowledge. The real danger from these misconceptions is that they impede the truth and cause electrical workers to misjudge hazards and risks... View full abstract»

    In past decades, many efforts have been given to improving the Residual Current Device (RCD) that has been the major and only means for electrocution protection since 1955. However, all of those efforts are based on the principle of RCDs, which are no longer in accordance with modern appliance usage, and in many cases RCDs may cause nuisance trips or fail to work. This paper proposes an innovative... View full abstract»

    Most companies' electrical safety programs do not include a live work policy. Of the companies that include a live work policy it is mostly comprised of a brief statement that their company does not permit live work to be performed. By not incorporating a concise policy into the electrical safety program it could have a costly effect on the operation of a company, the safety of their workers, and ... View full abstract»

    Having good procedures in place and having safe equipment are just two of the elements that are needed in having a good electrical safety program. People are the third element. People do not automatically, instinctively or intuitively follow the safe work practices contained in electrical safety procedures. They need to be led. How we lead and encourage people to be aware of the electrical hazards... View full abstract»

    The results of experimental arc testing of a nontreated cotton T-shirt with three different geometrical arc electrode arrangements are presented and discussed. Different geometries of arc electrodes result in different electromagnetic interactions of an arc current with current flowing between arc electrodes that in turn cause very different arc behavior. Ignition threshold of a T-shirt was determ... View full abstract»

    Though potential arc heat and blast energy from dc sources may be significant, the risk assessment for exposure to dc energy sources is often not performed because the requirement to do so is not understood. Making the task of quantifying dc arc energies more intimidating is that the professional engineer often assumes liability for any errors or omissions that may result in injury - or worse. Com...
