Building and Maintaining a Safe Substation Battery System 2
Substations are prevalent in all petrochemical facilities. Their function is to distribute power to the process units. Typically, there are either one or two types of battery systems within each substation.
Who’s Got the Power? 3
In Art. 100 of the 2014 National Electrical Code (NEC), the term Authority Having Jurisdiction (AHJ) is defined as “An organization, office, or individual responsible for enforcing the requirements of a code or standard, or for approving equipment, materials, an installation, or a procedure.”
Type TC vs. Type TC-ER Cable
You may be in violation of the NEC without even knowing it.
Sensitive Electronic Grounding in Industrial Locations 5
Thirty to 35 years ago, distributed control systems (DCSs), along with new analog and digital instrument systems, were in their infancy.
Small Dry-Type Transformers and Appropriate OCPD Sizing 11
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? 5
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.
