Cable type ... current carrying capacity

[Spoon]

although the underlying question still remains as to where can you get a cable fitting Table 4E2A ??? ... and what type/BS number is it?

Please read the last paragraph in post 6. Does your equipment apply?

Indeed I did, my initial issue was a lack of data from the manufacturer ... which has since been corrected.

However ... and as there is a strong possibility the property will become a B&B / Guest House ... Table H2 the second column relating to "Small shops ... business premises" is more fitting than the "... household ... dwellings ..." column ... the former requiring allowance for 100% of largest appliance plus 80% of second etc. ... so at the time of limited information and only having a maximum demand figure of 11.3kW my initial design had to at least allow for the potential of that amount of power to be drawn ... hence looking for a flex capable of handling 50A in free air or better still clipped direct ... it would have been easier to dress the cable in than 10mm T&E.

But ... all that is now history ... although the underlying question still remains as to where can you get a cable fitting Table 4E2A ??? ... and what type/BS number is it?

If you want flex then why are you looking at 4E2A, that is not the table for flex!

It does not refer to a specific bs number, it is a basic table for any unarmoured multi core with a 90degree operating temperature. Which will not be suitable for your application as the terminals you connect to will not be suitable for 90degree operation

"these are not the cables you are looking for...."

Try asking some manufactures perhaps.

Been there ... two different wholesalers ... one with exceptionally strong links to a cable manufacturer ... neither could provide an answer ... closest was 85degrees but CCC around 38A ... another suggested TQ cable but that still only had a CCC of 48A.

But ... as I now have no need for a 6mm flex that can handle 50A ... well that's the end of that ... as they say.

I would hope so ... although the other fly in the ointment was trying to find a cooker connection point that is rated at 50A ... all that I have found to date are rated for 45A ... including Crabtree who I thought might be the ones to use.

Doh!

Got side tracked with Note 3 beside the table ... "For cables having flexible conductors ...".

It's all a bit moot now then ...

Should have stayed in bed the other day ...

Both post 6 and I was referring to the 90 deg C bit, not the amperage.

Haven't got a copy of GN1 myself. But isn't reference to the small shops & business to multiples of appliances, not one, re applying diversity? ....'all now history', are you not installing the appliance now?

Your hopes will be in vain, there is no way any standard cooker plate will be rated for 90degree operation, they will be 70degree.

could perhaps usea crabtree shower pull switch, 50A rating, but don't allow the cord to dangle in the stew. :77:
