there are a whole set of 'regulations' about cable clamping and creepage which have to be met for connectors of this type. Suggest that you contact your local Trading Standards people who deal with this.

From what you've said, all of these connectors may need to be withdrawn and/or recalled!

Seems so, been wiring 32A/16A conectors all evening, all with decent clamps & doubled screws on terminals, yet the big boy 3PH 32A has no clamps..

Shocking !!! <excuse the pun LOL>

this looks like the PCE type connector - with the twist lock back shell.

If so, then this is quite normal, the main gland at the back of the back shell forms the gland and the strain relief, and no separate clamp strain relief is required.

I literally have hundreds of these type connectors in my hire stock ranging up to 63A 3 phase and have not experienced a single issue - so provided that you use the right size cable for the connector's gland, you will be fine.

Before you ask - all my connectors are sourced from reliable suppliers and are not chinese knock-offs.

To add, make sure you tighten up the gland properly, as Chris mentions, on these are also the mechanical strain relief, so are required to have a firm grip on the exiting cable.  They are a similar design to the Lewden/palazzoli quick wire plugs, nothing wrong with them at all.

If your at all worried, put a back shell on a length of cable and tighten the gland up and see if you can pull it off.

Cheers

Those PCE connectors are probably the quickest and easiest to work with (having spent whole days just wiring 16A cables) and the chuck type strain relief is very effective indeed because it clamps the cable from all sides rather than just squashing it flat.

If you are worried just put a Cut, un-stripped 5g6 end into the connector, screw it up and try pulling it out!!!
 
Cee-Norm (some of the best you can buy), Pazzoli and PCE all seem to be using Collect/gland system at the min which IMHO works well...

whilst the experts are here, does anyone know of a 3 phase connector (16a+) that accepts an m20 conduit thread?

I want to terminate some flexible metal adaptaflex conduit into a 5 pin connector for a generator fitted permanently under my truck to make it easier to remove it for servicing. Currently the connector is hardwired into an IP67 junction box but it's an arse to remake the connections after I've serviced the generator.

Incidentaly, 3 pins are for live, neutral and earth, and 2 pins are for a 12vdc lift pump, so a connector with a non standard keyway would be better so that someone (not me!) doesn't get a suprise when they get 12v down L2 and L3 . MK did a commando socket with an M20 thread but they don;t seem to do it anymore.
me so horny, me love you long throw.

What you are talking about doing is a bit naughty for various reasons, first the plug could end up in a 415V 3PNE feed, but a 4h as apposed to the very common 6h keyway, as you said would all but eliminate that....
 
Second if SELV (12V) and LV (240V) co-exist in conduit or trunking etc the SELV circuits must be insulated to LV standards, IE you sould have a barrier (Like use a bt of 2 core and a bit of 3 core flex...)
 
Personally I'd look at something like this :-
 
 
but if you want to do the BS4343 thing McKennes Ceeform (IP67) use a PG thread for the rear gland that can be adapted to M20 with a standard thread adapter....

Might be a bit overkill and expensive but if you look at Harting connectors you could design your own using their modular inserts so it'll be incompatible with anything else out there.

You can probably make lots of things mate with M20 conduit with a bit of epoxy!
