Guides
All guides- Test and tag in data centres: AS/NZS 3760 intervals, scope and registers
AS/NZS 3760 intervals across a data centre, which items are in scope, what operators expect from tags and the asset register, and how to line re-test cycles up with tenant moves.
- RCD testing schedule for data centres in Australia
How often data centre RCDs are push-button and trip-time tested, what operators and insurers ask for, what each record should hold, and how Type A, Type B and Type S devices suit server-rack feeds.
- Data centre periodic verification checklist (Australia)
What gets re-tested on a data hall distribution board and floor PDU after fit-out changes and on a periodic schedule, mapped to AS/NZS 3000 and AS/NZS 3017 tests, with a printable checklist.
- Why we built Field Efficient, and how it's changing the way tradies work
The questions we kept hearing from sparkies and technicians, and the app we built to answer them: flexible capture from any tester, AS/NZS validation, branded reports and test cards built for phones.
- Using Field Efficient with ServiceM8
Connect ServiceM8, import jobs with their clients and sites, and send finished test reports back to the ServiceM8 job diary. What it can see, what it never changes, and how matching works.
- GPS-stamped test results: proof you were at the board
Optionally stamp every reading with GPS at the moment of capture, resolved to a street address, linked to a map, and printed on the report only when you choose.
- Test & tag labels that verify themselves: Bluetooth printing + QR scan-back
Print durable test tags on a Zebra Bluetooth label printer at the board, each with a QR code that clients can scan to verify the test, and you can scan to recall the full record.
- From paper test sheets to portal-ready: retiring the triple-entry
State portals like eCert and ESVConnect are mandatory. The clipboard and spreadsheet in the middle aren't. How one validated capture feeds the client report and the certificate fields.
- Field Efficient vs electrical calculator apps: different tools, different jobs
Calculator apps check the maths before the work; Field Efficient proves the work after it: capture, AS/NZS validation, reporting and state certificate prep.
- Field Efficient vs job-management apps: do you need both?
Job-management apps run the business: scheduling, quoting, invoicing. Where they stop at blank compliance forms, a dedicated testing app takes over. An honest comparison.
- Australian electrical certificates by state: what to lodge, where, and when
NSW CCEW, VIC COES, QLD Certificate of Testing & Compliance, SA eCoC and WA eNotice: the certificate, the portal and the deadline for each mainland state, verified against the regulators.
- AS/NZS 3000 verification: the tests every installation needs
The mandatory verification tests AS/NZS 3000 requires before a new installation is energised, in order (dead before live), and what goes on the report.
- Test & tag intervals: the AS/NZS 3760 schedule (Australia)
How often electrical equipment must be tested and tagged under AS/NZS 3760, by environment, plus what the test involves and what goes on the tag.
