BUILDING PROJECTS

The plans are called schematic designs; they usually involve a rough layout of the floor plan and some simple views of the exterior of the home if there is an addition.

In residential and commercial buildings, most components of electrical installations are hidden from sight - only elements like lighting fixtures and receptacles are exposed, since their function requires it. The role of electrical systems in building interiors is much more evident in industrial settings, where there are no dropped ceilings or dry walls to hide conduit, junction boxes and other accessories.

  • AC and DC voltage testing techniques
  • Testing of motors and generators
  • Transformers and switchgear
  • Cables and accessories
  • Battery system and protective relay system
  • Power distribution system maintenance
  • Grounding, ground resistance measurement
  • Insulating oils, fluids and gases
  • Electrical safety and precautions

However, any movement of a positive charge into a region of higher voltage requires external work to be done against the field of the electric force.
