Opinions on the load of this cooker circuit???

[telectrix]

better safe than up before the man in the funny wig.

i once had to go to court . magistrate said " have you been up before me before? i said " don't know, your worship. what time do you get up?"

You could work out the load by dividing it by 0.4, some do, if you do it will be about 16 amps haha

 

[Joe S]

I nearly spat my tea out at that!!!:laugh3:

 

[telectrix]

divide by 0.4? that would be 40/0.4 = 100A better get the 25mm out. sorry mike. couldn't resist that one.

 

[MDJ]

sorry x (times) lmao, that was a blooper haha

 

[Guest55]

25a just seems low to me. Just means that all my circuits have been super safe, lol!!

i've managed to squeeze all 25 circuits on the entire first floor of a retail installation design down to a tiny , winey , measily 48amps per phase

i used a man's man's diversity ;-)

 

[Rampantchilli]

Is that how the calc should be done?? My old boss taught me the other way which is how I came up with 31A

not sure if thats the way to do it, but i just follow whats taken into account in the order its mentioned.

another thing that is so rarely taken into account is reference method, by the regs almost none of the reference methods allow 32a on 6.0mm except perhaps ref c,
i think 101 or 102 would still be ok for the load but not sure off the top of my head

 

[telectrix]

worst is 103 at 23.5A.

Excuse this question if it's stupid but isn't diversity used to get a rough estimate where not all outlets will be used at the same time? Isn't it quite likely that the oven and all hob rings will be on at the same time and cause a maximum load?

 

[telectrix]

not exactly, cookers are a one off, inasmuch as 1. not everything will be switched on at the same time. and 2. the rings and oven elements are thermostatically controlled, so that, even when all are on, they will not all be pulling full load at the same time.

Your right mate
Probably Only at Christmas though ,with a kettle plugged in as well, maybe a bit of low voltage depending where you are.
Typical of the “experts” on here just quote the book don’t use any common sense.

 

[MDJ]

They may all be on very rarely but I doubt they will all be on max, almost unheard of unless the wife cannot cook properly LMAO

 

[Des 56]

Put the oven on and put all the rings on maximum
I can assure you,it will not draw current that would equate to the sum total rating of all the rings and oven

 

[MDJ]

Your right mate

No, No he's not

What if they were?

Never Happen, your trying to start a discussion over a near impossible situation

With respect
No sorry that’s not my intention, the point I am trying to make is that the book is only a guide and certain things should be taken in to consideration when assessing a situation.
Diversity is a judgment not an exact science and I feel that just doing the maths is not enough.
Where I live we still have abnormal low voltage on certain parts of the island, this must be considered, its not in the book.
Right off you lot go, pick the snot out of that, I have put my tin hat on.

Forget the big names of today like Man utd etc
When Spurs won the double,they were thought of by me and many others as the Aristocrats of football,the best,living football legends,l,the ultimate football team and I was a young kid and not even one of their fans :clap:

Na can't be arsed M8, as It happens I am hands on and site man not a regs man, and only 5% of my work domestic, but a cooker is something which diversity can be allowed and thats the end of the matter, the book is irrelevent, it's just an obvious choice for the spark designing the load in a house, no need to attempt to scrutinise this point down to what ifs and maybes, pointles, carry on by all means I will enjoy the banter for sure, and the way you carry on it will follow you around.
