Residential Wiremen

Residential Wiremen work solely in residential settings (single and multi-family dwellings). Major duties for Residential Wiremen include:

  • Planning and initiating projects
  • Establishing temporary power during construction
  • Establishing grounding systems
  • Installing underground systems (slab/foundation)
  • Rough-in (frame stage)
  • Installing wire and cable
  • Trim out
  • Perform "hot" checks
  • Troubleshooting and repairing electrical systems

In performing these duties, Residential Wiremen must use many different kinds of tools, ranging from simple one and two-hand tools (such as wire-cutters and screwdrivers) to power-assisted tools like electric drills and screw guns. They occasionally operate heavy equipment such as trenchers.

Over the course of the three-year Residential Wireman apprenticeship program, apprentices must become competent in many technical areas. A recent job analysis identified 85 specific knowledges that are important for Residential Wireman job performance. A few of the most important ones are knowledge of:

  • The National Electrical Code
  • How to work with energized circuits
  • Blueprints, including symbols used
  • Electrical schematic diagrams
  • State and local electrical codes
  • First Aid
  • OSHA 10
  • Hazardous materials
  • Specific job safety rules
  • Proper wire/cable to use in different circumstances

Some of the most important skills to be learned are:

  • Skill at performing CPR
  • Skill at reading a wire table to determine conductor size required
  • Skill at terminating aluminum or copper cable
  • Skill at splicing twisted pair cable
  • Skill at terminating twisted pair cable
