I've done simple PAT testing before but not really appreciated the intricacies of the test settings, just been shown what to connect where and how to push a few buttons until 'PASS' appears on the screen. Having just purchased my own PAT PrimeTest 250 and watched a short training DVD from the vendor I have learned a lot, and already found a problem at my regular work place - a 10A fused mains lead connected to a 3A rated computer. Obviously this is wrong and I want to correct it, but have questions...
Should I be OK with 5A mains leads and fuses on IT equipment that is rated at 3A or less? If the PSU on the computer states 3A, do I have to use a 3A fuse in the plug?
Is it OK to simply replace the 10A fuse with a 3A in the plug for these pieces of equipment (they all use typical IEC computer mains leads), I assume all IEC leads and plugs are rated for 13A fuses but I just wanted to be sure it was a sensible thing to do.
I may already have answered my own question, as I am writing this I am opening up a brand new IEC lead and the plug is rated at 13A, inside is a 5A fuse. Good job I opened this plug too, the cord grip was not screwed down properly. I notice the moulded IEC connector end of this cable actually has 10A 250V stamped on it, does this mean that the 13A plug is not supposed to be on the other end of the flex? The flex itself has nothing on it apart from the place of manufacture. The plug has a label on it "Fitted with BS 1362 5A Fuse", which is what's actually inside it.
Sorry for the basic questions, just want to get it right!
