6Kw Cooker

[Electroglow]

Hello all.....

Now before u all start I know what you will say.. I will explain after...

How big will you expect a cooker cable to be on a 6kw oven?? In trunking rcd protected. Say around 20m distance.

Thanks boy and girls

After diversity you could possibly get away with 2.5mm T&E,,, but I haven't done the full calcs

 

[Sidewinder]

10mm sq at least if the install method is 103, even if in trunking, however, does no take into account the volt drop or anything other than the CCC direct from the tables in 7671.

Else perhaps 6mm sq.

I have no idea of the installation methods or whether it is even wired in insulated & sheathed flat cable, which my 10mm above is based on.

However, Noz is also correct.

So, it can be seen from this that there is more to cable sizing than the current demand/OCPD CCC.

More info needed, sorry.

Twin and earth...

 

[SPECIAL LOCATION]

[Riggy]

What's the vaue?

 

[Electroglow]

No just a 45a switch

 

[wozz]

any derating factors? 

whats the install method?

Not having a pop here Electro  but have you lost your BRB---BGB  or OSG  ? 

Presuming its S/P

Presuming cable is not run through the inside of a furnace @ 1000 deg,C 

Presume its not covered with 15 ft of lagging 

Presume its T/E 

Try 4.00   or 6.00  mm  after you've checked your books.

Domestic, hotel etc? Your diversity calcs will vary but as said above look in the On Site Guide. 

 

[Electroglow]

Lol it's not an actual question just a general rule when installing a cooker in a domestic house. Above was a example, I was making the situation up..

Ur average cooker is 4-6 kw ? Correct

So if you no the cooker is 6kw then how many of you would automatically think 6mm cable???

 

[steptoe]

there is no general rule for anything electrical apart from the guidance of 7671

 

[Electroglow]

U and I both know that we know what cables to run for what it's needs... Depending on loads

10 socket 2.5 ring final

10aockets 4.0 radial

10 point lighting 1.0 - 1.5

The regs is to be followed I agree but to calc every cable size!! Bit silly When ppl with experience already knows

And so on

 

[steptoe]

you have obviously never worked anywhere but a 3bed council semi then?

 Ive wired RF's in 4mm before, and lights in 2.5

 

[Electroglow]

As a said depending on load... I was referring to domestic yes.

 

[Electroglow]

I have wired commercial lights in 2.5 also with a 10a c type breaker

 

[Electroglow]

Again I have also wired a ring in 4.0mm I think I have even done it in 6.0mm b4..... Industrial unit

 

[steptoe]

Ive done both in domestic,

too many factors to be just using a

'well cookers are 6mm and sockets are 2.5 if its a house' type of look at it.

This seems a bit of a pointless thread?
