semi armoured

Lectrician I take your point but if it dont work why do it, honestly i have tried HO5 and 7, heat resistant flex of all sorts, but the oil wins, it even gets into the conduit that why I thought about SY as you can get a better "seal" at the ends but if it doesn't work then I will admit it.

Having replaced many 'plastic' cables including SY due to softening by oil/grease or other chemicals, I say SY is not the way to go.

terminating the screen ( lets not call it armoured, it's not.. you can cut through it with a knife.. ) is really easy.

strip back the outer, push the braid to get some slack, bend at the outer sheath, using a screwdriver pick a hole in the braid and pull the inner core out of it, pull the braid tight again and now it's empty it will collapse on itself.
sleeve it and either heatshrink over the outer/braid junction, or use tape to tidy it up.

Hmmmm - that didn't work with the 50mm2 4 core SY cable I used last week
Brass SY glands for that one.

I know what you mean though and do the above on a regular basis with 1.5mm2 3 core SY cables.

It works ok for me putting 5 core 50mm2 SY cables into 128A CEEforms

I'd like to see you pull 3 meters of the inner pvc/pvc core through the braid directly where you've stripped the outer sheath to!

Still, your plug and socket arrangement could be perfect for making a domestic electrical installation one big portable appliance, negating the need for notification to Building Control for Part P compliance

I didn't say its easy but once the original bend is through the rest follows fairly easily

Its been done several times to my knowledge but wiring in a building is still classed as installed by the LA whether wired in direct or plugged in.

I helped make 3 of those cables to power some hairdryers in a hotel and the guy I was working for insisted it be done that way, I wanted to unpick the braid.

 

[GaryMo]

I know. It was pretty much tongue in cheek and aimed at those here who think once it has a plug fitted then wiring becomes exempt from the fixed installation.

Well Iam wrong on this, spoke to tech department of Lincat and they say like a few of you guys no don't it'll go soft eventually, also what I assumed was HO stuff in the clients maintenance stores is'nt its black heat flex. so thats why it went weird.
Still you live and learn cheers guys for getting me to dig deeper

Most wholesalers keep HO7 these days, usually in 2.5 and 4mm, 3 and 5 core.

If you look at the loadings and the current carrying capacity (or manufacturers recommendations), you may be suprised when you can get away with 2.5mm (more so obviously with TP).

Just beware that whilst the cable may be able to run at 85 degrees C the cooker switch and connections will be rated lower meaning you can't run the cable at the maximum current ratings quoted.
