Just had a customer ring up as the kitchen fitter wanted to speak to me about the electrics.
He said
"I can't install the oven & hob on the same circuit & I've called my usual sparks who agrees, they need to be on seperate circuits & switches.
And the earth isnt connected to the water pipe in the kitchen, you've left it hanging loose".
"the earth is connected to the water pipe at the nearest copper pipe work available which is next to (3mtrs from) the cu, done this way as the mains water is pvc and opposite side of the property. was noted as deveation on cert when cu was changed 2 years ago by me. The bit of green sleeved earth you see in the kitchen is an old supplimentary bond that was connected between a socket & the old sink.
As for the cooker & hob I have to say your mate is wrong, so long as the circuit design complies in all aspects with regard to load, where is the problem?"
"The oven isnt rated for 32 amp it's only 13amp, We have to install a 16amp radial & connect to that"
"So wheres the difference between connecting to a 16amp radial via a fcu or socket or to a 32amp 6mm radial via a fcu or socket?"
"well I'm not happy doing that we dont normaly connect to a socket or fused spur"
"so you connect a 13amp appliance directly to a 16amp circuit?"
(ok I know the cable & appliance will be capable of carrying 16amp, just started getting miffed at the blokes "my mate say's" line)
"Yes like it should be, on it's own radial 16amp circuit"
So to pacify the bloke I said I'd call back in a few mins after redoing the calcs for the circuit & making a quick call to Bosch.
The teckies at Bosch said the model of oven is max 2.2Kw (9.5amp) & it is upto the installer to make connection to a circuit by any means that is suitable & complies with regulations (words to that effect). The hob is 7Kw full load.
Called the fitter back & his responce.... "My mate say's he wouldn't be happy with that set up, so I'm not to happy about connecting the oven up"
"Fine leave it & I will drop in tonight on my way home & connect it"
So thats where we are....I'm doing some free customer relations tonight, after the fitter has done a "thats not how it's done" job to the customer. Customer also told me the fitter wanted my details before he'd undertake connection of any electrical items in the kitchen ...hood/pelmet lights/dishwasher....
expect a search has been done to see if I'm pee'd.
Any way that turned into a long winded post so.....what I were wanting to ask was....How many do put seperate circuits in for both hobs & ovens even if the the total load isnt so high as to dictate the need for seperate circuits?
Have to add in the above job the hob is directly above the oven, so again why waste time effort & materials to put in two points of isolation.
