The National Electrical Code (NEC), ANSI/NFPA 70 considers information technology equipment (ITE) installed in ITE rooms—more commonly called computer rooms—as special equipment.
This article will look at the requirements in the National Electrical Code relative to information technology equipment and the correct use of Article 645.
Unsafe electrical services, improperly wired electric outlets, and extension cords running across walkways are just a few of the electrical hazards that might be found at some fairs.
Ground-fault circuit interrupters can be used successfully to reduce electrical hazards on construction sites utilizing temporary wiring methods.
This article will present methods and explanations about receptacle testing in patient care areas as per the NEC and NFPA-99.
The proper application of overcurrent protection rules for air-conditioning and refrigeration equipment can be made relatively easy by following a few basic steps.
Overcurrent protection for motors and motor circuits is a little different than the rules for conductors as specified in Article 240, because motor loads have different characteristics than general lighting and other loads.
Electrical inspectors involved with aerial high voltage facilities frequently have to determine whether electrical conductors are in compliance with the National Electrical Safety Code (NESC).
