[RWJ]

Paint it green n yellow lol

PMSL....... I'm sure some would try using it as a CPC if they sold G Y conduit lolololololo

Tel: Garage is going at the other side of the garden and about half the distance from the house compared to the shed (garden is a damned odd shape), electrical materials already bought for the garage (though have my eye on a nicer CU). Thats what I had in mind anyway for the garage - 6mm2 3 core SWA buried under the gravelled drying green (SWA is currently looped up waiting on the council to get back to me on "garage design guidelines", already told me they want it fireproof....which means either block work or if its timber /steel framed - fibre cement/metal cladding externally AND internally plasterboarded walls....its a detached garage...not a house....they asked what I would do if it caught fire....grab a hose/run for it - depending on the severity of the fire...I'm near certain the framework would withstand fire for more than long enough for me to escape...but thats another point entirely......)
Shed is always just going to be a store room, so given that going to fuse the supply down to 13 amps, double socket in the shed, SFCU to run a single light.
Yes I'm aware it was a daft question I asked at the start of this thread.....I think I'll go off and lurk oncemore....

Motors is different because you only just flexible cables for the final connection so there isn't a suitable armour.

Don't know why you would think that mate?
I've taken armoured cable direct to the motor terminal box thousands of times!

Because its what I was taught, think it features in the regulations somewhere or at least one of the guidance notes and also gets referred to quite often on this forum.

Doing something thousands of times doesn't automatically make it right, it can mean you've done it wrong thousands of times.

Hopefully someone else will see this and be able to confirm either way

Not sure if I'm understanding what your saying here to tell the truth.
Taking the Swa direct to the motor terminal box and connecting it there with the correct gland is normal mate believe me
Quite a few have threaded entries too so it seems a shame not to use them.

Are you saying you've been taught to gland the swa into a terminal box then use flex to go to the motor terminal box?

I am saying I was taught that only fine stranded/flexible cables are able to withstand the work hardening effects of the motors vibrations.

Ok that's different then and can understand where you and your 'teachers' are coming from.

All I will say on the matter is.........................if 'motor vibrations' are going to affect the connections in the motor terminal box then the install of the motor needs to be looked at asap...............any vibration affection the electrical connections will, undoubtedly, **** the bearings etc too lol.
There should be no vibration getting to the connections but can see the reasoning behind the thought

Also dave.....................running a flex to a motor from a 'transit box' with stranded cores is 100% ok .............don't think i'm saying its not.............but...........it depends on the situation mate.

Swa is there to be used when 'extra mechanical protection is needed' so running it and terminating it into the motor terminal box is normal...............I do offshore 'hazardous area' installs sometimes and it's all swa or braided connected direct to the motor or from a MCC or panel.

As long as the terminations are done correctly....................it doesn't need to be 'fine' stranded
I'm sure Eng will enlighten us on the max size Swa that should be used when terminating direct into motor?
I'm only a boy and 37kw motors is max size I use with no problems using armoured.............a mere child

Well I terminated 2x 185mm 3core directly into a motor the other day.
