IEEE 141 Recommended Practice for Electric Power Distribution for Industrial Plants, clause 12.2.4.1
IEEE 1637 Guide to Select Terminations for Shielded Alternating-Current Power Cable Rated 5 kV - 46 kV - Low Voltage Cable Testing and Inspection Techniques The following inspections and tests should be performed before energizing newly installed low voltage wire and cable rated 600V or less.
- Medium Voltage Power Cable: MV 105 cables This article is used to explain the most popular styles of copper medium voltage (MV) power cables and their usage.
- Dead Break Elbows v Load Break Elbows A dead-break elbow requires the cable to be "dead" in order to be detached or attached and is typically rated for 600A. A load break elbow can be attached or detached live or under "load" and is typically rated for 200A.
- 200A Industrial Loadbreak Elbows [PDF] Industrial Loadbreak Elbow connectors are fully shielded and insulated plug-in termination for connecting cable to transformers, switching cabinets and junctions equipped with loadbreak bushings.
- Calculating Minimum Bending Ratios The following are the minimum values for the radii to which insulated cables may be bent for permanent training during installation.

- Wire Temperature Ratings and Terminations Conductors carry a specific temperature rating based on the type of insulation used on the conductor. Common insulation types can be found in Table 310.13 of the NEC, and corresponding ampacities can be found in Table 310.16
- Tables of AWG wire sizes The table shows various data including both the resistance of the various wire gauges and the allowable current (ampacity) based on plastic insulation.
- Bending Radii and Pulling Tensions The minimum bending radii for single and multi-conductor cables rated 600 volts and less, and without lead sheath, shielding or armor.
- Installation of Cables and Busways General overview of various cable and busway installation methods.
- Inspection and Test Procedures for Metal-Enclosed Busways Visual/mMechanical inspections and electrical tests for metal-enclosed busways.

- Tan Delta Cable Testing: Overview and FAQ [PDF] Tan Delta, also called Loss Angle or Dissipation Factor testing, is a diagnostic method of testing cables to determine the quality of the cable insulation.
- Partial Discharge
- What is Partial-Discharge Resistance? [PDF] Partial discharges occur when the local electrical field intensity exceeds the dielectric strength of the dielectric involved, resulting in localized ionization and breakdown.
- General Guidelines for Online Partial Discharge Testing of Power Cables Partial Discharge is a localised discharge in the insulation medium due to high voltage stress that does not bridge the space between the two conductors. Partial Discharge testing of Power Cables is one of the diagnostic methods to detect and locate incipient faults in the cable insulation.
- Tan Delta
- Tan Delta Cable Testing Tan Delta, also called Loss Angle or Dissipation Factor testing, is a diagnostic method of testing cables to determine the quality of the cable insulation.
- Fiber Optics
- The right tools for accurate fiber-optic testing There are five industry-standard ways to test premisesfiber-optic cable (three for insertion loss and two for OTDRs), depending on how you use reference test cables for your setup.
- Optical Time Domain Reflectometer (OTDR) The Optical Time Domain Reflectometer (OTDR) is useful for testing the integrity of fiber optic cables. It can verify splice loss, measure length and find faults. The OTDR is also commonly used to create a "picture" of fiber optic cable when it is newly installed.
