Pat testing

Also there was s 3p oven rating 9.8kw on an isolated switch. Where does this rating stand? I just did a visual and stickered it ,am I wrong

Yep you should have done earth and IR tests

Ok il scoot up and do it

Aye earth bond is 0.00 on most items

Thats surprising, doesnt sound right. We just had our PAT tester calibrated and on the earth bond for IEC leads out of about 30 leads everyone read 0.00ohms, so Ive sent it back.

Also as mentioned look for the 2 squares symbol, if its not there then test it as class 1...

what about atm machines, that cant be unplugged ???

some earth bonds were0.04 too 0.08 but most were resistance free

i couldnt see no class 11 on computer equipment, is this mostly class one as well. i.e flat monitors and destops

Hi, The way to tell if something is Class 1 or Class 2 is to look for the 'square box' symbol. If you see that symbol then it's Class 2, if not then you must treat it as a Class 1.

Extension leads should ALWAYS be made of 3 core cable, and will need testing for Earth Bond and Insulation. Most PAT Testers also have the facility to do a Polarity test as well.

When testing a kettle the best place to get a good earth is the element. If it's a solid base kettle then try putting a screwdriver onto the base and putting the clip onto that.

If your PAT Tester doesn't have a facility for testing extension leads (all the modern ones do) then another option is to carry out the earth and insulation tests on the kettle, then plug that into the end of the extension lead and do the same tests again. You might get a slightly higher earth bond reading, dependent on the length of the cable.

Hope this helps!

and if theres no evidence of the double square logo....or your unsure/can`t confirm/not verefied that an item is either class 1 or 2.....then treat it as class 1...

Unplug the IEC lead and test that then check the monitor/tower for damage...

if it was hard wired into an isolator I would not class it as portable. that's part of the fixed instalation.

Emm no its not, a fixed appliance comes under ISI&TEE formally PAT a fixed installation stops at the socket /FCU/DP isolator thats what is causing a lot of bother within PAT as guys who are PAT trained and not electricians are not authorised to go into FCUs and DP isolators so the urban myth of if it aint got a plug top on it you dont PAT test well thats just plain wrong if its electrical equipment no matter how its wired then it supposed to be PAT tested.

Just to add storage heaters , ovens, hoods, come under ISI&TEE

Yes point taken and I don't disagree but as a PAT service it stops at the Plug for me. I'm happy to test hard wired items with my safeblock but not at normal rates!
