Fixed Appliance Testing isn’t a PAT test; it is a separate function altogether, and is more of an electricians job than a PAT testers, but for some reason electricians don’t like to do this task, so we have to. However it is not as straightforward as a PAT test.
A fixed appliance needs testing in the same way we do a PAT test – it needs its wires ‘plugging’ into a PAT tester, to run appropriate tests. But those wires are secured to the mains wiring system inside a fused spur unit (FSU). An FSU does the same job as a plug – the appliance cable goes into it, the wires are secured by terminal screws and the cable is protected by a fuse. That is where the similarity ends.
We can’t just unplug it like a normal appliance, it needs the wires taking out. As it is permanently attached to the mains, live electricity, we need to isolate the power, to make it safe.
Isolating the power means turning it off.
So this means we probably can’t do it whilst your business is operating; out of hours access will need to be arranged, unless you can cope without your sockets for about half an hour!
So if you want your fixed appliance testing carried out, we recommend you talk to us about the options available to you.
