cooker fuse down grade

[Barker]

Hi All

I have someone who has been convinced to down grade the fuse for his cooker as the Gas man convinced him it was a good idea.

the set up is the cooker is 2500watts and has a 45 amp switch with a single socket, and these are on a 32 amp MCB. he plugs his kettle into the socket.

Question is would you down grade the breaker or put in a fused spur. It is all fitted into nice tiles so I can't go chopping the wall out.

cheers

I cannot legitimately see any reason for change at all, or of what benefit it will serve.

Tell the customer they need to downgrade the gas pipe to the boiler and wait for the response .

if you have got a load of 2.5 kw from the cooker and a load of 2kw from the kettle,

that works out to about 19.5 amps,

20a mcb will be running close..so i would stick with the 32

What is the plumers reason to downgrade? Does he believe the current carrying capacity of the cable is reduced for some reason (like he fell out the loft hatch holding the 10mm cable to break his fall and its CSA is now only 1.2mm or he has just laid 500mm of insulation over ir)?

unless the manufacturers instructions for the cooker says what rating MCB/fuse it must be protected by, i dont see any problem leaving it as is

ignore the plumber they are usually wrong.

If there is an outlet plate you could change that for an unswitched socket if you wanted. I think I would leave it as it is.

I don't see a problem there, take no bread poultice !

Advise aginst it, change the MCB if still requested to do so, fill out relevant certification etc. Then obviously charge for the return visit to replace the original MCB when requested to at a later date.

If you do take the job, remember its not a 5 minute job - well, changing the MCB will be... but itll take a lot longer to write the EIC!

Just re-read the OT and have changed my mind . Is there a concern with the size of the flex between the cooker and the switch ? If the cooker has been changed for a smaller one the flex may only be 1.5 mm , in which case the guy is right as the MCB was protecting a 6mm ,say , is now too big for the flex.

sure about that? after all, if its fixed load, then its protected against overload current, which then leave just fault current to sort. if the smaller cable can take the fault current to open 32A MCB, then all is good.

there was a thread not too long ago about undersized cables etc

Or as previously mentioned, change outlet for socket and plug cooker in

I would ask, would the customer accept an electricians view of the gas supply and order a gas installer to renew his 20mm gas pipe for a 25mm pipe because it has too many bends in it?

My thoughts are that the plumber has done one of them 2 day electrical courses for part p so now he can earn more doing a bit of rewiring, roofing and general pain in the butt moaning.

Until part P is abolished for a more easily controlled system, we will have plumbers,kitchen fitters, and those cold calculating idiots who call them selves handy men doing all the electrical work with no regard for public safety or knowledge of what they are doing is in any way dangerous.

Lets face it there are only 3 wires in a cable its so easy to connect them to a plug and switch on.

Regardless of how long the run is, how many cables are bunched, how much insulation it has to run through,the method of installation, the overcurrent protection characteristics,the eventual total draw or demand per cable, its all simple, 1.5 for the lights,2.5 for the sockets, 6mm for the cooker,10mm for the shower forget the earths they are never needed to be upgraded, sod the TT never seen one of them before just put the earth into this hole here.Sleeving you dont need that, its for those who do not know what they are doing we know its earth, got to watch them cowboys love.

I think you get my point, and should be posted on another topic I suppose, I just wish part p was controlled just like corgi and the now safe gas schemes.

I would then feel justified in paying my dues in subscriptions.

yea, and there is only one 'line' in a gas pipe, so should be even easier for us sparks to do their job than it is for them to do ours, but then corgi/gas safe doesnt have a 'limited scope' scam we can join and call ourselves 'gas engineers'

Who left the pi all over the place?! Anyone here just finishing a diet want to relieve the forum of some pi?
