Description

Objective:

The course objective is to demonstrate current techniques, practices, protocols and standards that assist investigators in the evaluation of electrical systems and associated components.

Learning Outcomes:

  • apply and demonstrate electrical theory to include current, voltage, and power
  • use Ohm's and Joule's Laws to calculate unknown values
  • identify and differentiate the theories and physics of electrical systems to determine relevance in fire investigation
  • apply the fundamentals of electric utility system operations, including generation, transmission, distribution, and typical electrical service supplies to buildings and facilities
  • analyze the components of fuses and breakers to determine if the source of heat for ignition was the result of tampering or a failure
  • analyze the failure modes and limitations of over-current protection device (OCPD) types, styles, and brands
  • demonstrate knowledge of branch circuit components and installation methods
  • evaluate safety methods, equipment, and techniques used to evaluate electrical systems
  • evaluate the source, path, and load components to determine their potential involvement in a fire investigation
  • discern and evaluate electrical faults, failures, and associated high-resistance connection (HRC) characteristics
  • using knowledge of source, path and load, build a service entrance and connect the appropriate circuits
  • apply arc-mapping to the reconstruction of a fire scene to determine the area of origin
  • evaluate artifacts to determine if an appliance failed, if it caused a fire, or if the appliance was damaged as a result of the fire
