ELECTRICAL QA/QC AND RESPONSIBILITIES In engineering it is very important to make sure of the quality of engineering work done. This is very important as a small mistake in quality of service provided can cost not just money but also lives. Considering this, various governments and quality certifying institutions have released laws and standards that are to be maintained from the beginning to end of a complete installation process. Maintaining such standards at the time of construction or installation is known as Quality Control. A thorough maintenance and servicing of such installed/ existing systems, conducted periodically to make sure that there are no further faults on these systems is known as Quality Assurance.
