C-H,
We normally use PDL-Brand IP56/66 plugs over here, they come in any pin configuration from 3-pin single phase up to 63A 5pin + 2 control pins.
Wan't to know more about this system?
Go to www.pdl.co.nz and click on PDL Products,then click on Industrial, it should auto-scroll across to 56 Series, lots of other cool rubbish on this site. [Linked Image]
