    Arc flash on single phase or DC systems according to NFPA 70E?

    Hi everyone, I know that IEEE 1584 equations are only for 3-phases AC systems. But in NFPA 70E, I cant see anything else about system limits but 50V to ground or more. Anybody knows if we can use NFPA 70E equations on single-phase or DC systems if a customer wants it?

    Cable impedance

    Hi guys! I'm trying to build a cable impedance database that could be used in my studies. Does somebody know a good reference about cable impedance including various types of cables, various voltage level, etc. Thanks! JPEG
