What is going on

Job J-26-1147 at Fairmont Engineering Works in Geelong installed a new 63 A three phase supply and isolator for a CNC machine. The Leading Hand completed the tests on Friday and the compliance register shows the results as Tests recorded. The General Manager checks every prescribed work certificate before it is lodged and has asked for a review of the test sheet against the policy and procedure before he signs. The customer wants the machine running on Wednesday. The test sheet shows earth continuity, insulation resistance, polarity and fault loop impedance, but the residual current device test line is blank and the instrument identification is written as 'van tester'.

Subject: Fairmont CNC supply: tests and certificate before I sign

Ryan has finished the three phase supply for the CNC machine at Fairmont, job J-26-1147, and the tests were done on Friday. Before I check and sign the certificate I want you to go through the test sheet against the testing and certification policy and the procedure, confirm every mandatory test was done and the values are within the standard, check the instrument used was in calibration, and enter the results properly in the compliance register. If anything is missing, go back to site with Ryan and complete it. The customer wants the machine running Wednesday.

Your brief

Review the test results against the testing and certification policy and the installation testing procedure, identify what is missing or inadequate, arrange and record the outstanding tests, confirm the instrument and its calibration, complete the compliance register entry properly and prepare the certificate of electrical safety for the General Manager's check.

Work through it

You do not need to do it all. Doing a few of these will show you what the work is like. Your ticks and notes stay on this device.

Read the installation testing and certification policy and the testing procedure and list every mandatory test for a new three phase final sub-circuit and isolator.
Review the test results on the compliance register entry for J-26-1147 and the test sheet, and identify gaps, unclear entries and any value outside the standard.
Check the instrument register to identify which tester Ryan Doherty carries and whether it is within calibration, and record the instrument identification on the sheet.
Arrange the outstanding residual current device test and any retest with Ryan, record the measured values on the test results and commissioning sheet, and note who performed them.
Update the compliance register entry with the complete results, the instrument and the test date, and set the status to Tests recorded.
Prepare the certificate of electrical safety with the installation details, work performed and tests carried out, ready for the General Manager's check.
Write a short note for the General Manager explaining what was missing, what was done and confirming the installation is ready to be energised.
Update job J-26-1147 on the job board to reflect the certification step and the planned energisation date.
