| Post subject: | Arc Flash Label Placement Responsibility |
Who can be responsible for the Arc Flash Label Placement once the Arc Flash labels are generated? Can the Electrical Engineer or Contractor generate the Arc Flash Labels and then mail them or deliver them to a qualified person for installation? Or is it the sole responsibility of the Electrical Engineer or Contractor to install these Arc Flash Labels? I did do some Google searches to see if this question has already been asked, but my apologies in advance. Thank you. |

I don't believe this is spelled out in any standard. NFPA 70E Article 205.3 states: The equipment owner or the owner's designated representative shall be responsible for maintenance of the electrical equipment and documentation. So from my view, it is about what the contract states. Who is responsible for applying the labels? Having the person performing the study apply the labels might minimize confusion regarding where the labels go. However, if there is good guidance on where the labels go, a qualified person might be able to apply them. Disclaimer: This is my personal opinion and not an official interpretation of any code or standard. |

As Jim stated the closest thing to this in the standards just puts the responsibility on the owner or their representative. I take this to mean they need to ensure it is done and not that they have to physically apply them. I strongly recommend labels be applied by someone that performed the analysis. I have seen too many issues when a contractor performed the study and the facilities personnel applied them and also when a contractor performed the study but had persons that were not part of the analysis apply them. I've seen MCC's where labels where different labels were applied to each bucket. Upon closer examination it was found these labels were for the downstream equipment fed from each bucket. This resulted in multiple, inaccurate, hazards being identified at the MCC and no hazards identified at the downstream equipment. |
