Just come back from a repair job on an Indesit washing machine and had a nice tingle having touched the drum.Ouch.
Got out my mains tester and surprise surprise it shows no earth on the socket under the work bench plus a double socket for the kettle and toaster on top.
Took multimeter out and buzzed across the earth pins and nothing.

Very old thatched cottage with owner living there for 6years and just the good old fuse box on the wall with downstairs wiring through the 30amp fusewire.
Tried to take off very newish looking metal double sockets to have a look for the customer but they had been grouted in?
Informed customer who did not seem to be interested in such a dangerous situation as he was busy watching rugby on the TV, have to go back with a part and get him to sign a letter for me as I reckon the sparks will not be contacted.

My relatives thatched farmhouse roof took 18 minutes to burn down the complete roof.
Mmm some people just want to be in the Darwin book of death 2010.
Thanks again for pricing.

i see where this is heading…

with regards to this, if we declined the fit because we werent happy with the lack of componentry would we still be allowed to insist on payment because the customer requested connection, as opposed to part p?

Ok maybe I should expand a little 😉 . Oven rated at 2.5-3kw supply circuit 30-45 amp fused at consumer unit

As Mal was hinting there and from my own experience it appears that when a small oven is delivered and it has a 13amp moulded plug on the end, most installers just chop off the plug and hard wire it to the spur box with little regard to the consumer unit fuse rating. Only when it’s the other way around and the oven demands a 30/45 supply line and there’s only a 13amp spur nearby does the installer realise a Part P spark is needed to put in a new supply line.

It’s therefore commonplace for me to find that a single oven in need of repair has been connected up in this way by someone? Possibly blissfully ignorant as to the consequences or not the least concerned other than to connect it up and get it running.* Human nature personified…:rolls:

* A good and local friend of mine is a Part P spark so when I encounter such circumstances I point them in his direction to remedy the situation. He likewise calls me when someones oven, washing machine etc has a problem. 😉

Nice one Martin, you may now take any prize of the top shelf 😆

Just to elaborate and hope I am not teaching “Granny to suck eggs” but there are probably a few that are not sure what I am on about.

The old ohms law tells us that: watts divided by voltage = amps.

Roughly for every 1000w of heater then that equates to 4 amps (1000 divided by the 230- 250 supply voltage ), so a oven of 2.5 kw requires 10 amp 3kw 12amps.

I fitted a new Elux oven yesterday. it was rated at 3kw and Elux. quoted fuse protection of between 16- 20 amps, bit strange really as the oven could only be used as a fan oven or grill, not together. Only one element could be in circuit at once. Max 2kw ish 😕

I carry a supply of 13 amp sockets plus 13amp fused spurs, a box of backboxs etc. and install what is required, bit of a pain in the ar8s when you only expect it to be a short job and this comes along.

I am not exactly complying to Part P as I don’t issue a certificate of additions (kitchens and bathrooms) but as I trained as a electrician then I am willing to fight my corner if anyone decides to challenge me over it. My opinion is that the oven is now installed as it should be and a lot safer to boot, more than the previous electrician or kitchen fitter left it.

It makes one think the next time we decide to connect one up 😉
