All tools used in trade need to be PAT tested - the HSE insist on regular PAT testing
I used to think that but-
From the HSE FAQ,the answer to "Is Portable Appliance Testing (PAT) compulsory?"
No. The law simply requires an employer to ensure that their electrical equipment is maintained in order to prevent danger. It does not say how this should be done or how often.
it's certainly a (small print) requirement in my Insurance.
Very good point. I hadn't thought of that.
The rules which once applied only to construction sites now apply to all self employed trades (PUWER 98, etc)
Quickly scanning through the PUWER HSE website I can't find any mention of PAT. They do however state that power tools must have a CE cert. I guess that means that some American cordless tools that do not have EU distributors would therefore not be legal even if you could find a 240v battery charger.
I did find this on an third party site
Are PAT tests a legal requirement under PUWER? No. PAT tests are useful to show that portable appliances are electrically safe but they are not a legal requirement under PUWER.
As to PAT testing of negative earth 230 volt tools being just a visual inspection, that's not true - the tools still need to be put on the tester and the tests run (AFAIK earth continuity and 500 volt DC insulation tests to metal components such as chucks as a minimum)
You are absolutely correct, I was having a senior moment. Although the tools are double isolated, yes they do need to be tested. Just out of interest, when conducting the touch leakage test the probe needs to be connected to the tool whilst the tool is running, in the case of a drill how do they do they connect a crocodile clip to a spinning chuck?
