Draft of Test & Tag standard available for comment
Posted on Monday, November 23rd, 2009
The draft of DR 3760, In-service safety inspection and testing of electrical equipment is available to comment on. The closing date for comment on this draft Standard is 12 February 2010.
This draft is a revision of AS/NZS 3760:2003, and specifies procedures for the safety inspection and testing of low voltage single phase and polyphase electrical equipment, connected to the electrical supply by a flexible cord and/or connecting device.
This draft also includes fixed RCDs and portable inverters.
NOTE — Additional requirements for portable generators are covered by AS/NZS 3012.
[Hint: This draft will look VERY much like the final version which will cost you abut $100 to buy, so it's well worth downloading - even if you don't intend to make a comment.]

Patch Panels
Tue, 9 Mar 2010, 04:03 pmI had visited a community Theatre that had an incorrectly wired patch panel and people were getting electric shocks from it, but were putting up with it because it had been wired up by a volunteer. It was told they fixed it straight away, I hope it is not still the Old Water Wheel.
If you do not know the status of a patch panel, then test and tag it as it is plugs and sockets, not a fixed wiring install that is permanently connected to the fixed mains wiring.
This is what testing and tagging does well, visual inspection, insulation, polarity. Two polarity tests should be done, the first using the appliance tester, the second using a neon style polarity tester with the lead plugged into the mains. The test mains supply should be rcd protected for this testing. After a test has been done on every "lead", that is from every plug to the end of every socket, you know the polarity is correct, so a visual inspection should be done every time the patch field is used.
