Confirmation

[SimpleSimon]

Evening gents
Next week got an install. A sub-pump at the bottom of an estate being fed from 200m of SWA, about 120M of this will be underground the rest cleated to a the walls and roof.
The current is 3.8 per phase on a triple pole MCB. What I would like please is confirmation on the materials needed just so I can prepare myself.

200M of SWA
External glands at both ends with banjos and fly earths.
Cable Markings for underground.
Cable markings for identification at both ends.
Cleats.
6A Triple pole MCB.
IP rated junction box to connect SWA to pump flex.
Clear sealant.

Can any of you guys think of anything else or anything Ive overlooked?

Thanks

Im going to use a 4 core SWA so three lives a neutral and one more for an earth to use as well as the armoured sheath just to be safe.

Need a 5 core then mate? Don't order that length of cable and find you need an extra core lol

Fit fuses or MCB at the fuse board for the minimum cable size. Protect the motor with O/L’s. Fit an isolator at the point you joint the SWA to the flex, you’re covered then for provision of local isolation and it give a convenient and accessible point for the joint. If you can protect the flex with Copex.

Bomb proof!

Haha!! Yeah your right there Keith. Can't believe it got this far into the thread without someone noticing my maths. Ta
Tony thanks for putting in simple terms. Starting job Wednesday I'll let u all know how I get on.

Oh and can anyone recommend where I can find cable marking? The plastic ones? I can find them in large quantities but not smaller.

Buy a kit from RS.
You’ve then got them for use in future.
