Fixed Appliance Testing Problems

[Marvo]

What you finding is correct, I used to work for indesit and on fridges/freezers the pot(compressor) an its pipe work is earthed however their is no connection to the metal cabinet, the reason being the cabinet is completely isolated from the electrical system, their is no way for the cabinet to become live with in the system.

This doesn't make sense to me, the hermetic compressor stands on rubber feet that are for absorbing vibrations, they're not classed as insulators.

I remember there was another similar thread about this a while ago but I can't remember the outcome. When I've got time to search I'll post the link.

Thanks ack,
I did not think it was, hence all the wiring running around the appliances under question in the thread is not actually double insulated...
I am taking your info as correct as I have not checked the standards.

Thanks 'net' but always refer to original documentation otherwise you'll end up as those who state: ' well the chap at the trade counter told me it was Ok to stuff this probe up my girlfriend's bottom, how was I to know the regulations recommendation states that it inadvisable to use a Tesla coil internally ?' .......if you see what i mean - lol

I would before I put pen to paper as it were on an official document & always do, however, this time of night after the day I've had.
NO CHANCE!

It must be in the air - i too have had one of those s**t days - no probes or trade counter encounters either.

Is flex double insulated, remembering that FTE is not, it is insulated & sheathed.
Not something I have thought about, so I would have to check myself...

No. It is insulated and sheathed. The sheath may be made of an insulating material, but its insulation properties are not tested and it is there simply to provide mechanical protection. Cable is not double insulated.

Had similar recently. Washing machine and dishwasher under Worktops. Floor had been tiled and couldn't pull them out. FCUs tiled around and siliconed around. Customer didn't want any of it disturbed. Decided to carry out some ring final tests and IR the kitchen ring at CU with all other loads removed. Not perfect but sometimes a case of best endeavours. Had a clear result, no need to investigate further.

10 years ago when I did my kitchen out I fitted a sheet of 600x600x15mm ply in the space where the dishwasher and washing machine then put down a laminated floor and I have had 2 replace both recently ie slide out then back in so why cant a stupid kitchen fitter do the same

Then you obviously dont give your PAT customers any form of detailed certification cause if you did you would know that a modern PAT records each appliance and allows you to download it on to a PDF for the customers records...cant do that with a Megger!!

 

[marcusone]

Detailed certification doesn't require pat testers, downloads or PDFs. Just MFT, pen and paper cert. Sometimes I get the abacus out for calculations or to tot up the invoice

I can with my Megger PAT tester.
