Checking Appliance Earthing.

Zoomup
Today I spoke to the manager of a local chain of domestic appliance retail shops. The chain sells and installs appliances like cookers and ovens etc. I asked the manager if they carry out an earth fault loop impedance test to confirm adequate earthing of the supply circuits and good earthing of appliances like cookers. He said that they did not. He asked me what test gear is used to carry  out the tests. I was shocked by this. People are having appliances installed by unqualified installers and the earthing effectiveness is not being tested.


Also his shop has nuisance tripping of the R.C.D. when several appliances are turned on. In particular washing machines cause tripping. Probably down to the 50 appliances each leaking a small current to earth via their internal mains filters. Get the cheapest quote. That''ll do. That's Norfolk for you.

    An installer who installs cookers, ovens, and other white goods day in day out having had a basic company training which is likely to incorporate shadowing a colleague for a couple of days is generally regarded as sufficient competence to continue at that level of work.

    I remember a young lady who enrolled on one of my courses to learn about electrical installation and maintenance as she was working for a national company installing and repairing/replacing hand driers in service station toilets. At least I made the electrical work as interesting as possible and she stuck it out for a year before the company decided she was qualified enough...shame, she had the right attitude and abilities to have been a proficient spakie.
