Underground Electrotechnology

Best practice literature to be covered in our 11 AM session today are listed below.  These codes and standards ensure safety, reliability, and compliance for underground electrical and telecommunications installations:

2028 National Electrical Safety Code

  • National Electrical Code (NEC), NFPA 70
    • Relevance: The NEC, published by the National Fire Protection Association, is the primary standard for safe electrical installations in the U.S. Articles 300 (Wiring Methods), 310 (Conductors for General Wiring), and 230 (Services) cover underground wiring, including burial depths, conduit requirements, and direct-burial cables like Type UF and USE-2. For example, NEC 300.5 specifies minimum cover depths (e.g., 24 inches for direct-burial cables, 18 inches for PVC conduit).
    • Key Aspects: Rules for conductor protection, grounding, GFCI requirements, and conduit types (e.g., Schedule 80 PVC). Adopted by most U.S. jurisdictions with local amendments.

ANSI/TIA-568 Series (Commercial Building Telecommunications Cabling Standards)

  • Relevance: Governs low-voltage telecommunications cabling, including underground installations. TIA-568.2-D (Balanced Twisted-Pair) and TIA-568.3-D (Optical Fiber) specify performance requirements for cables like Cat6 and fiber optics, including maximum distances (e.g., 100 meters for twisted-pair).
  • Key Aspects: Ensures signal integrity, proper separation from high-voltage lines, and compliance for plenum or direct-burial-rated cables. Voluntary unless mandated by local codes.

IEEE 835 (Standard Power Cable Ampacity Tables)

  • Relevance: Provides ampacity ratings for underground power cables, critical for sizing conductors to prevent overheating.
  • Key Aspects: Includes data for direct-burial and ducted installations, considering soil thermal resistivity and ambient conditions. Often referenced alongside NEC for high-current applications.

UL 83 (Standard for Thermoplastic-Insulated Wires and Cables)

  • Relevance: Underwriters Laboratories standard for wires like THWN-2, commonly used in underground conduits. Ensures cables meet safety and performance criteria for wet locations.
  • Key Aspects: Specifies insulation durability, temperature ratings, and suitability for direct burial or conduit use. NEC requires UL-listed cables for compliance.

OSHA 1910.305 (Wiring Methods, Components, and Equipment)

  • Relevance: U.S. Occupational Safety and Health Administration standard for workplace electrical safety, including underground installations in industrial settings.
  • Key Aspects: Specifies approved wiring methods (e.g., armored cable, conduit) and enclosure requirements for underground cable trays or boxes. Focuses on worker safety during installation and maintenance.

CSA C22.1 (Canadian Electrical Code)

  • Relevance: Canada’s equivalent to the NEC, governing underground electrical installations. Similar to NEC but tailored to Canadian conditions and regulations.
  • Key Aspects: Defines burial depths, conduit types, and grounding requirements. For example, low-voltage cables (<30V) require 6-inch burial depth, like NEC.

Notes:

  • Regional Variations: Always consult local building authorities, as codes like the NEC or AS/NZS 3000 may have amendments. For example, some U.S. states reduce burial depths for GFCI-protected circuits (NEC 300.5).
  • Low-Voltage vs. High-Voltage: Standards like TIA-568 and ISO/IEC 11801 focus on low-voltage (e.g., <50V) telecommunications, while NEC and IEC 60364 cover both power and telecom.
  • Practical Compliance: Before installation, call 811 (U.S.) or equivalent to locate underground utilities, and obtain permits/inspections as required by local codes.
  • Critical Examination: While these standards are authoritative, they can lag behind technological advancements (e.g., new cable types like GameChanger exceeding TIA-568 limits). Over-reliance on minimum requirements may limit performance for cutting-edge applications.

Smart Infrastructure is a global opportunity worth £2trn-4.8trn. The world is experiencing a fourth industrial revolution due to the rapid development of technologies and digital abundance.

Smart Infrastructure involves applying this to economic infrastructure for the benefit of all stakeholders. It will allow owners and operators to get more out of what they already have, increasing capacity, efficiency and resilience and improving services.

It brings better performance at lower cost. Gaining more from existing assets is the key to enhancing service provision despite constrained finance and growing resource scarcity. It will often be more cost-effective to add to the overall value of mature infrastructure via digital enhancements than by physical enhancements – physical enhancements add `more of the same’, whereas digital enhancements can transform the existing as well.

Smart Infrastructure will shape a better future. Greater understanding of the performance of our infrastructure will allow new infrastructure to be designed and delivered more efficiently and to provide better whole-life value.

Data is the key – the ownership of it and the ability to understand and act on it. Industry, organisations and professionals need to be ready to adjust in order to take advantage of the emerging opportunities. Early adopters stand to gain the most benefit. Everyone in the infrastructure sector has a choice as to how fast they respond to the changes that Smart Infrastructure will bring. But everyone will be affected.

Change is inevitable. Progress is optional. Now is the time for the infrastructure industry to choose to be Smart.

Perspective: Since this paper is general in its recommendations, we provide examples of specific campus infrastructure data points that are difficult, if not impossible, to identify and “make smart” — either willfully, for lack of funding, for lack of consensus, for lack of understanding or leadership:

    1. Maintenance of the digital location of fire dampers in legacy buildings or even new buildings mapped with BIM.  Doors and ceiling plenums are continually being modified and the As-Built information is usually not accurate.  This leads to fire hazard and complicates air flow and assuring occupant temperature preferences (i.e. uncontrollable hot and cold spots) 
    2. Ampere readings of feeder breakers downstream from the electric service main.  The power chain between the service substation and the end-use equipment is a “no-man’s land” in research facilities that everyone wants to meter but few ever recover the cost of the additional metering.
    3. Optimal air flow rates in hospitals and commercial kitchens that satisfies both environmental air hazards and compartmentalized air pressure zones for fire safety.
    4. Identification of students, staff and faculty directly affiliated with the campus versus visitors to the campus.
    5. Standpipe pressure variations in municipal water systems
    6. Pinch points in municipal sewer systems in order to avoid building flooding.
    7. How much of university data center cost should be a shared (gateway) cost, and how much should be charged to individual academic and business units?
    8. Should “net-zero” energy buildings be charged for power generated at the university central heating and electric generation plant?
    9. How much staff parking should be allocated to academic faculty versus staff that supports the healthcare delivery enterprises; which in many cases provides more revenue to the university than the academic units?
    10. Finally, a classical conundrum in facility management spreadsheets: Can we distinguish between maintenance cost (which should be covered under an O&M budget) and capital improvement cost (which can be financed by investors)

 

 

Telecommunications Service Point

Today we get down in the weeds to examine the point of common coupling between a building and a telecommunication service provider.

Education facilities often require a more diverse approach to designing and implementing ICT systems than that of a typical commercial building.  First of all, educational settlements are frequently one building. That means not only does the ICT infrastructure need to meet the varying demands of a specific building, but multiple buildings must all be integrated into one cohesive design.

In an environment of providing multifunctional spaces within one building, it is common to find a combination of commercial, industrial, data center, health care and entertainment environments within just a few buildings; hence our preference for the word “settlements” over the more widely used word “campus”.

TIA Standards

ANSI/TIA-568-C series: Telecommunications Cabling Standards.  Specifies the requirements for various aspects of structured cabling systems, including cabling components, installation, and testing.

TIA-569-B: Telecommunications Pathways and Spaces.  Provides guidelines for the design and installation of pathways and spaces for telecommunications cabling.

TIA-606-B: Administration Standard for Commercial Telecommunications Infrastructure.  Specifies administration practices for the telecommunications infrastructure of commercial buildings.

Our inquiry cuts across the catalogs of several other standards developers:

NEC (National Electrical Code).  NEC Article 800 specifically addresses the installation of communications circuits and equipment.

ISO/IEC 11801: Information technology — Generic cabling for customer premises.  Defines generic telecommunications cabling systems (structured cabling) used for various services, including voice and data.

IEEE 802.3: Ethernet Standards. Defines standards for Ethernet networks, which are commonly used for data communication in buildings.

UL 497: Protectors for Paired Conductor Communications Circuits. Addresses requirements for protectors used to safeguard communications circuits from overvoltage events.

GR-1089-CORE: Electromagnetic Compatibility and Electrical Safety. Published by Telcordia (now part of Ericsson), this standard provides requirements for the electromagnetic compatibility and electrical safety of telecommunications equipment.

FCC Part 68: Connection of Terminal Equipment to the Telephone Network. Outlines the technical requirements for connecting terminal equipment to the public switched telephone network in the United States.

Local building codes and regulations also include requirements for the installation of telecommunication service equipment.
