Industrial Electrics & Control Fundamentals for non-electrical personnel (Part 2)
Industrial Electrics & Control Fundamentals for non-electrical personnel (Part 2)

Duration:
5 days

Prerequisites:
Attendance on our Industrial Electrics & Control Fundamentals Part 1 course or equivalent level of basic electrical knowledge & competence. To get the most benefit from this course (and not hold back other others), delegates should be able to successfully complete the pre-course assessment.

Aims:
This course has been developed primarily for non-electrical maintenance personnel as a Skills-Update course so that fitters & mechanically biased craftsmen can work safely alongside qualified electrical personnel. A brief review of basic tools & techniques is followed by coverage of a range of common modern industrial components & their principle of operation. Tips & techniques regarding how to safely check for correct/abnormal operation are provided. Safe Working Practices are covered & the fundamentals of troubleshooting motors, motor controls, circuits & systems are explained with plenty of practical exercises.

Objectives:
For specific course objectives see Training Record Log.
