  • Grounding Electrical Systems National Electrical Code

    Aug 29, 2018 | Michael Johnston
    These days, multiple power sources can be present in a single building or structure. Many of these are what the National Electrical Code (NEC) calls separately derived systems. Transformers, batteries, fuel cells and generators can supply these systems. An electrical system produced by a generator is either required to be grounded as a separately derived system or it is not, and the key to this is the transfer equipment.

  • Equipment Requirements National Electrical Code

    Jun 21, 2018 | Michael Johnston
    Per the National Electrical Code (NEC), electrical equipment must be rated for voltage and ampacity, and it is required to carry normal current and the amount of available fault current during ground-fault or short-circuit conditions. Warnings also must be on equipment that is likely to need examination, adjustment, servicing or maintenance while energized.

  • Wiring in Hazardous (Classified) Locations National Electrical Code

    Aug 12, 2022 | Michael Johnston
    Electrical wiring in hazardous (classified) locations is significantly more restrictive than wiring in general unclassified locations. Good design ingenuity for systems in these environments is to locate as much of the electrical wiring and equipment outside the classified location. The basic approach of addressing the hazardous (classified) location is to remove one or more components of the fire triangle—oxygen, fuel and an ignition source—to reduce the possibility of an explosion. Electrical installations present significant ignition sources for these environments.
