Small Dry-Type Transformers and Appropriate OCPD Sizing 8
Most petrochemical industrial facilities have numerous small (30kVA or 45kVA) transformers spread throughout the process units serving lighting and power distribution panelboards.
Equipment Grounding Conductors and Voltage Drop 3
Currently, manufacturers of multi-conductor cable assemblies such as Type TC and MC cables include a standard size of equipment grounding conductor (EGC) with a given size of ungrounded conductor, as per UL standards.

Does Your VAM Need a Local Disconnect? 4
The most common reference in the industry for valve actuator motors (VAMs) are motor operated valves (MOVs).
Analyzer Cable Tray Systems and the NEC
All petrochemical plants have analyzer shelters or stations.
Tank Farms and Conduit Sealing 2
Nearly all petrochemical facilities and refineries have tank farms that store feedstock or end products.
Welding Receptacles or Power Receptacles?
In petrochemical plants and refineries, there are usually many 480VAC, 3-phase receptacles scattered throughout the facility.
Pyrophoric Materials and NEC Article 500
In the 2014 Edition of the National Electrical Code (NEC), the last sentence of the first paragraph in Sec. 500.5(A) states: “Where pyrophoric materials are the only materials used or handled, these locations are outside the scope of this Article.”
Obstruction Clearances Behind Vertical Ladders
Not all requirements needed to make a safe installation are found in the National Electrical Code (NEC).
Hermetically Sealed or Factory Sealed
The 2014 edition of the National Electrical Code (NEC) [Sec. 500.7(J)] describes “hermetically sealed” as one of the protection techniques allowed in classified areas.
T-Codes in Hazardous (Classified) Locations
When using electrical equipment in classified areas, such as lighting fixtures in Class I, Div. 2 locations, it’s an NEC requirement that the surface temperature of the fixture doesn’t exceed 80% of the autoignition temperature (AIT) of the gas or vapor involved, or shall be marked with a temperature code (T-Code) [501.130(B)].
Medium-Voltage Cable Insulation Ratings 1
Below Table 310.104(E) in the 2014 National Electrical Code (NEC) are important notes that could be critical in the type of insulation that is specified or purchased for industrial locations.
Industrial Substations
The term “substation” is used loosely throughout industrial facilities. The term is actually defined in Part I of Art. 100 of the 2014 Edition of the National Electrical Code (NEC). However, the definition leaves a lot to be desired for Code users.
Instrument Tray Cable
Why you have to know what you’re doing when specifying ITC cable
Grounding in Industrial Locations
Ever wonder why petrochemical plants and refineries bury so much copper wire and ground rods throughout the process units when it isn’t required by the NEC? The NEC establishes the minimum requirements considered necessary for safety.
Industrial Locations and Critical Operation Power Systems 1
It shouldn't be news to those who keep up with the NEC that Art. 708 [Critical Operation Power Systems (COPS)] was added to the Code in the 2008 edition. What may be news to some, however, is that in the 2008 proposal stage, chemical plants, refineries, oil terminals, or any other facility where a failure or outage may affect the nation's economy or security, was included in the scope of Art. 708.
