Hi Andy, the client has not arranged with the orginal installers of the generator to sort out the wiring to be compliant.
I decided that I do not wish to be involved in determining if it is VOV wound & further to ascertain if the centre tap can be disconnected from earth & bridge the neutral to earth etc..
I have issued a COC, specifically excluding the Alternate power & stated that a supplementary COC will be issued by the installers for the Alternate generator supply.
The client is upset with me, as he cannot believe that the installation is non compliant.
When I asked wether they had issued a COC, he said that they were proffesionals?
Shortly after I did the earth leakage test while using generator power which did not trip & showed an earth fault,
the client emailed me, stating that since I left his oven was not working properly as well as his DSTV decoder.
He did all the switching & started the generator. All I did was the earth leakage test.
I replied & stated that after conducting all tests ie PSCC, Earth loop impedance, Earth leakage etc.. with Eskom power being supplied, there
were no problems with his appliances.
The only thing that is common with regards to the problems is that the power was supplied by the generator.
I aslo stated that Decoders do not like to be switched on & off repeatedly & can fail prematurely, especially PVR's which normally experience hard drive failure.
I am also assuming that his oven has some type of electronic control regarding heating & timer, which could be affected by Generator power ie, voltage, current & frequency.
On a funny note. Did a COC the other day. When I opened the DB, this is what I found.
Took half an hour to remove this guy.
