Fuse too big on fridge

[John-SJW]

A small under counter AEG fridge. Instructions say it is fitted with a 13A fuse in the plug. Also states it must be replaced by a 13A fuse. The fridge is drawing 0.32 amps. A 13A fuse is ridiculously oversized. If having a mcb or RCBO at the CU for just the fridge, a 1.00mm cable can be run on a radial for it.

The instructions do say that a qualified or competent electrician must fit the appliance, so a get out for them. If the electrician say 3A will do then that is that I suppose. Do many ignore these types of instructions and say insert a 3A fuse in the plug? Safer.

Understand what a bus bar is then look at a Wago.

I understood it last time. Gave up trying to argue though. You wouldn't listen to anyone elses opinion.

Clearly whoever they are this person possesses more intelligence and common sense than the rest of us, not to mention the persons making up the JPEL/64 committee. It’d be easier if we all just bow down to the superiority of their arguments and accept their word as truth instead of following the clearly illogical and inferior regulations that have gotten us to this point...

Sisyphus had an easier task than reasoning with this one.

Hes not wrong tho..

A sole appliance, on a radial, drawing a third of an amp, on 1.00mm cable on say a 10A mcb is electrically sound and safe. Are you saying it is not?

You are supposed to be electrically trained. To think. Now do not look at table. Tell me where it is electrically not sound or safe? I will be waiting a long time.

Again mate, don't change the subject. I did not mention 'safe' in any of my posts.
Quoting you: "1.00mm would not be electrically incorrect." Post #69.
This is incorrect. 1.00mm is electrically incorrect. Look at the regs.

Just chop the end off a 9" nail and shove it in the plug top's fuse holder. Job done.

Is this the Pickhill Bantam welder thread?

A quick scan of the lengthy thread and diving back to the original discussion here, most appliances with a 13amp plug top are what we class as fixed current equipment and therefore do not need overload protection and this is why we can see fuses rated higher than the CCC of the flex that supplies the unit, if the manufactures guidance requests a lower fuse rating then that is what should be fitted but the likes of appliances with motors often have a 13amp fuses covering flexes that have a lower CCC simply to allow for inrush where the common 5 or 3 amp rated could periodically nuisance fail, you can argue that you fitted smaller fuses with little or no issue but when millions of products are sold then the industry may see a reflective % of these nuisance popping which requires extra staffing to their help lines and unnecessary costs may also be put on the user, these and many other reasons are why we don't always fit the lowest rated fuses that we could theoretically get away with.
The exemption from overload protection can be applied to most household hard wired circuits if necessary but common practice and rule of thumb often doesn't see us doing that, one of the few circuits that is classed as a variable load and needs to have a max rated fuse for O/L protection is a ring main for obvious reasons that there is no max current demand that we can calculate as it is an unknown variable, other regulations can also interfere with front end fusing like lighting circuits where the lamp-holders themselves can specify a max fuse rating for the circuit it is on.-

I have a nice wee beer fridge in my study. It looked a bit bare, so i put an old 100A fuse on it, thinking it would look nice, but no...fuse too big on fridge
(sigh)back to the drawing board...

A reg quoter again. Lokks like someone who has been trained. I told you not to look at regs, then assess, then tell me where it is not electrically sound and not safe. I am still waiting.

You have a very strange attitude. You remind me of the antivax type people with the way you argue and refuse to listen to reason.

There will always be cases of things that are electrically sound, but don't necessarily comply with BS7671. The regs cannot cover every eventuality. You are free to do things that don't comply, as long as you justify your deviations.

Assuming there is no fault of course. In a fault condition it may draw more current than it is designed to, with a fire/electrocution risk. That is where correctly sized overload protection comes in - to nip the danger in the bud.

I have seen enough innards of burnt out appliances that would have benefited in safety aspects having a correctly sized fuse in the plug, with 13A being far too high.

Your point about manufacturers increasing fire/electrocution risk because of profit is relevant.

Did you understand what I wrote? Looks like you never.
I told him not to look at regs, then electrically assess, where an appliance with a current draw of 0.3A on a dedicated radial, with 1.00mm cable with 10A mcb. I asked him to tell me where it not safe. He continually spouted the regs, unable to assess it, and still has not.

The scenario I gave is 100% safe. The regs say minimum of 1.5mm for power, which is good practice. There is a reason why they set that. So as the hard of thinking do not cause fires.

Electricians are trained to follow procedures and regs - think inside the box.
Graduate engineers are educated to think - promoting outside the box thinking. That is why the British are very inventive. Training and education are different. The British system does differentiate between the two.

Please listen to people.

He isn't saying it is not safe. He is saying that it doesn't comply with the regs.

And as I say, there are many circumstances which may be safe, but which do not comply with the regs. The regs cannot cover every eventuality.

And give it a rest with the bold text - it's very patronising and completely unnecessary.

I know that.

He wrote: "You also talked about using an incorrect cable size."
The cable size was not incorrect, it was perfectly suitable and safe. Not conforming to a reg is another matter. He could not figure out the difference.

I did listen, with a lot of narrow minded nonsense coming from some. They should do the listening, not me. Darkwood came out with one of the few sensible replies.
