| Post subject: | Arc Flash Labels for UPS |
I have a question about arc flash labels for UPS. Should we calculated incident energy for both incoming power supplies of the UPS (main supply and alternate supply) and then print label for the worst case? Also, should there be separate labels for 480V-UPS-unit and the 208V-UPS-distribution panel? Thanks. |

I would also do what you proposed. Worst case label. I only stick one label in all electrical equipment, unless the client is adamant about doing otherwise. |

How are you handling reduced energy let through switches with regards to downstream devices? |
