Heat resistant sleeving

[saffa1982]

My apologies first of all for the stupied questions that will follow

I am about to terminate my oven using 6mm t&e. Continuit and IR on circuit is good.

As it is just t&e I would like ensure that cables is well protected from potential heat from oven and as I dont ants to replace cable i have decided to use heat resistant sleeving.My questions are, do I strip the grey pvc and sleeve each core indidvidually or do I just put the sleeving over the grey pvc already around the cores.

Also what size sleeving should I get.. Am i correct in assuming as 6mm2 cable I should get the 6mm heat resistant sleeving

I have posted a link to show the size i am looking at

Just go with some H07 cable, saves messing about with sleeving and is the best option for this job.

Thanks andy.

I Appreciate that h07 is probabaly best option, ,but due to various constraints i.e ripping most of the kiitchen apart I want leave the current 6mm in place and provide the heat resistance through sleeving?

Would I remove the grey PVC and sleev each core individually including the cpc or would I just sleev over grey pvc . What size sleeving for the cores if i have to strip and i dont have to strip grey pvc what size sleeving would cover the whole wire

Thanks for helping

Call a spark in, what you are thinking of doing could quite easily kill you.

Is this a full blown Cooker or just an Oven ??

Most single ovens are now less than 3kw and should be fused correctly.

Most ovens /cookers have mains connections behind a plate on the rear and that area is not usually subject to excessive heat in my experience. So your T/e will probably be OK.

Its a oven with a grill at the top . 5400 watt . The wire in place is 6mm t&e and the circuit is protected with 32a breaker.

I am not changing anything on the circuit, i pulled out the oven to clean behind and decided for additional safety to sleave with heat resistant sleeving and hence my quesions

i have the testing on circuit and continuity and IR is all good

The termination point is at the back of the oven , i have a feeling you are right about it ot gettng too hot there , But I would rather be double sure in case some of wire touches outer casing when pushed back and the casing heats up

 

[Evans Electric]

If you feel happier with sleeving then fit some .

Well I have lost count of how many I have installed and have always used TW/E and not had a problem yet. Unless there is something seriously wrong with the oven the case really should not get hot and the terminal block also should not. Just ensure you do the connections tight.

That is the plan and hence the questions. Do i strip the grey pvc and sleeve teh cores and cpc or do i just sleeve over grey pvc.

What size sleeving for 6mm2 t&e cores , is it as simple as getting 6mm sleeving

i have posted a link for the ones i am looking at.

Thanks for the advice

youll find that that sleeving wont fit over the FTE seeing at its 6mm O.D whereas 6mm FTE is 13.5mm x 7mm O.D roughly(TLC numbers)

 

[saffa1982]

thanks jono, what size sleeving Should I get?

Do i strip the grey pvc and sleeve each core or just sleev over the complete wire inclusive of the grey pvc

 

[batty]

Where are you sleeving internal of the oven or external?

 

[saffa1982]

external , upto the termination point on the back of the oven

---------- Post Auto-Merged at 22:06 ---------- Previous post was made at 22:05 ----------

external , to the terminating points behind the oven

 

[Jono Pashley]

If your going to do it...leave the grey sheath alone and sleeve the lot, you probably need something along the lines of 14mm sleeving which would probably end up setting you back more than a couple of metres of H07 tbh.

 

[saffa1982]

external ,upto terminating points behind oven

 

[batty]

Well you don't want to strip cable back before it goes into appliance you will be damaging the integrity of the cable. If you really want to do this get some heat shrink sleeving.

 

[kerching]

Think about it...

heat resistant sleeving is what it says on the tin...I resists heat IT DOES NO REMOVE OR ELIMINATE IT

If you oversheath the complete cable and it ges too hot inside due to conduction of heat then you have what is known in the trade ' a fricking great snot of melted cable'

If you sheath the individual cores then you have reduced the inter-conductor heat conduction, so there is far less chance of a short.

I have been doing this job for over 35 years and I can count the number of cooker cables that I have fitted heat res sleeving to on the 'toes of one hand'
