Counterfeit alert: Code of Practice for In-service Inspection and Testing of Electrical Equipment (4th Edition)

As many of you are aware from our previous articles on the subject (see ‘The counterfeit issue’ from Wiring Matters 50 – March 2014 ), some of our titles have been the focus of counterfeiters. Whilst we appreciate that everyone likes to get a good price for the necessities, buying from places such as Amazon MarketPlace and eBay can lead to inadvertently obtaining counterfeit copies of our books. We’ve found some significant errors in these fake titles and urge you to please buy from established retailers - we’ve put together a list of recognised retailers.


The fake titles we have been aware of so far are the On-Site Guide and the Wiring Regulations themselves. These are important books that most of you will be using either in your studies or on the job. If you follow the erroneous information in these books, you could either fail your exams or follow incorrect information in your line of work – which could well lead to fire and safety risks. Unfortunately, even though you can prove that you followed the information in your book, you could still be liable for prosecution if your work leads to fire, safety hazards or death – so please do take care with your purchases.

The most recent fake that we have discovered is the Code of Practice for In-Service Inspection and Testing of Electrical Equipment (4th Edition). This fake is easily identifiable by the spelling errors; see an example below from Table 7.1:

You will see that the heading ‘Equipment environment’ is missing the ‘t’ at the end, and that ‘Not recorded unless a fault is found’ appears as ‘Not recordet unless a fault is found’.

We’d like to thank everyone who has contacted us after watching BBC Fake Britain featuring this subject, or after reading through our previous articles on this. Please continue to let me know if you have spotted any fakes: We’re keeping busy on our side shutting down rogue sellers – but we need your help too!
