One of the biggest pushes for increased safety in the electrical industry over the past decade has been arc flash mitigation.  With the introduction of live work permit requirements and restrictions in the National Fire Protection Association (NFPA) code, it has become increasingly important to provide accurate warning labels on electrical equipment. These warning labels provide the contractors with critical information about the amount of potential energy that could be expelled in an arc flash event.  This information is used to determine the correct personnel protective equipment and limits of approach, so it’s important to be as accurate as possible.

Wick Fisher White specializes in created accurate system models, allowing us to calculate short circuit levels accurately.  This helps our clients avoid costly change orders associated with increases in updated equipment ratings during or even after construction. We consider all possible sources and modes of operation, whether for dual feed utility substations, parallel generator sets, redundant switchgear, or photovoltaic grid tie inverters. 

By doing so, we ensure that the calculated short circuit current reflects the worst case, and size the equipment accordingly.

We have extensive experience working with electrical distribution systems ranging from small businesses to major telecommunications central offices, mission critical data centers, and entire hospital campuses.  Wick Fisher White can help our clients navigate the new and complex code requirements for arc flash labels, personnel protective equipment (PPE), limits of approach, and live work permit applications.   We go above and beyond currently adopted standards and practices to maximize the safety of personnel operating and maintaining electrical equipment.  Our dedicated staff will work directly with all major equipment manufacturers, software modeling companies, and testing agencies in order to attain the highest standard of quality for all studies performed.
