Which Cable Gland?

[imroberts]

What size should I be using to terminate 4mm 3-core 6493X SWA?

Advice online seems to tend towards 20S however some sources recommend 20.

If I look at Prysmian specs (the cable is Prysmian though I haven't bought any glands yet) - they quote the cable as 15mm outside diameter and 10mm under armour.

The glands only quote a maximum under armour diameter which is 11.6 for the 20S and 13.9 for the 20 - suggesting both would be fine but the 20S potentially a better fit. The cable dimensions are quoted at 8.0 - 15.8 and 11.7 - 20.8 putting the cable pretty much at the limit for the 20S and roughly in the middle for the 20.

So - should I tend towards the bigger gland (will this be easier to fit with the cable not being at the limit?) or will the smaller be a better fit? Or am I overthinking it?

Whatever is the closest size to the cable diameter, so 20S.

Overthinking ! we don't do that round here

Another vote for 20s.

20S

Its borderline. 20s usually, but some cable manufacturers (the better ones), it will need a 20.

As lectrician says, that is an iffy size, 20s can be tight and 20 sometimes seems loose, sometimes the CW glands give more leeway to tighten up on
