Electrical Drawings and Schematics

Electrical Drawings and Schematics

This 2-Day Electrical Drawings and Schematics training course is designed to prepare electrical personnel with the ability to read and understand the electrical diagrams, recognize equipment and verify the integrity of the existing schematics.

Students will be introduced to electrical symbols, one-line and three-line electrical schematics and their content, including basic layout and legends. Participants will participate in practical exercises in schematic reading, diagram verification and the steps required for creating and maintaining accurate one line diagrams. Participants are encouraged to bring examples of their own facility's prints to use during practical exercises. Low, medium and high-voltage installations can be reviewed as requested by participants.

 

COMPLIANCE REGULATIONS:

  • Occupational Health and Safety Act and Regulations
  • Provincial Regulations
  • CSA Standard Z460 Control of Hazardous Energy
  • CSA Standard Z432 Safeguarding of Machinery
  • CSA Standard Z142 Code for Power Press Operations
  • Canadian Electrical Code 2006
  • NPFA 70E
  • Manufacturers Standards
  • Company Policy, Procedures and Practices

 

In order to comply with the above-mentioned regulations, complete and up-to-date electrical single-line diagrams and equipment operating and control schematics must be made available in the work place. These important documents are required to be updated as necessary or as equipment changes or is modified and sometimes verified on an annual basis. In addition, this two-day program is designed to provide knowledge of the various types of electrical diagrams used in the industry, and to develop the skills necessary to read, draw and interpret these diagrams.

 

YOU WILL LEARN HOW TO:

  • Create a block map of the installed equipment
  • Transfer the information to the one line diagram
  • Verify electrical prints and make changes to existing diagrams
  • Create and maintain regulatory compliant electrical diagrams

 

WHO should attend

Electrical technicians, field engineers, project managers, inspectors, contractors, and journeyman electricians who depend on effective skills and knowledge required in this ever changing fast pace electrically driven environment.
