Having a few thoughts on what should and shouldn't come under PAT testing under the COP 4th Edition. I have no doubt wall heaters screwed to the wall and connected via a flex and FCU should be PAT tested, along with hand dryers, but does the same apply to Handwash units and 5-10litre water heaters which are plumbed in to the water supply on fixed copper pipes, but also connected via a flex and FCU ?? Just want to get the facts straight before I approach the customer. Long standing Sparky but new to PAT testing.
