| Post subject: | Should Engineer Require an Arc Flash Risk Assessment? |
Hi everyone, it's my first post on this forum, but it has been very helpful in the past to read through the topics. I do both arc flash risk assessments as well as design engineering. I am currently designing and specifying a generator / automatic transfer switch installation for a public safety building. It is a single phase, 400A, 240/120VAC service. What I am wondering is if you think that the specifying engineer should require an arc flash risk assessment as part of the project, or should I make a recommendation to the client that one be performed, or neither? They have a budget in mind already that only includes the generator, transfer switch, and installation. Thanks! |

In a past life, I performed studies for both existing systems and systems where new equipment / construction was involved – the latter was usually specified by the designer. When I provided design services, the studies would often be part of the design. As a minimum, it would be prudent to at least recommend the owner have a risk assessment performed and cite the appropriate standard requirements. i.e. NFPA 70E, IEEE 1584, OSHA etc. When the importance is emphasized (safety), perhaps they will consider the study. |

When we hire consultant engineers at the university where I work to perform electrical designs for new buildings and major remodels I require they perform the studies. On small projects I do the studies myself. Here is what I require: https://www.bsu.edu/-/media/www/departmentalcontent/facilities/pdf/26%200573%20arc%20flash%20hazard%20analysis%20short%20version.pdf |

Most of our customers require a study be performed when new work is done, this is of course customers who have already had studies performed for all their facilities. At a minimum the customer should be made aware they should have one performed, but ultimately it is up to them if they want to spend the money to do so. |
