    Default Shipping container electrical socket

    I have a 20 foot shipping container that I have on a mine claim and I have a construction power pole and I'd like an electrical supply to the container.
    I don't need a permanent connection and what I'm thinking would be suitable is some kind of water proof fitting on the outside to plug in a power lead into and something on the inside where I can plug in a couple of leads.
    With the container having the channeled walls I could easily weld-up a mounting boxes on either side but I have no idea what would be suitable for this application and Google and YouTube hasn't been of any help.

    I wouldn't bother to weld up anything.

    The simplest/quickest solution would be to fit a rated weather proof power plug (not socket) to the outside of the container.
    The sort of thing they use on caravans.

    There are some really nice fully weatherproof ones available with a proper extension cord restraint.

    Realising that you will need a electrician to legally do it and it must then conform to ASNZ 3000 and 3001. Which means double pole outlets and switches.

    If the cheap caravan ones seem a bit flimsy then something like this and a weather proof DP switch added into the circuit would work.
    This is similar what the mens shed sparky used to connect up a container (but he didn't use a switch) using an extension cord to a GPO inside the shed.
    The thing on the LHS is called and appliance socket - similar to what is use on electric kettles and some computers power supplies..

    I like that, what do they look like on the inside of the container.

    Crikey Bob, I was talking about using them on the inside, not the outside!

    They look like the back of a 3 pin plug, ideally you need some sort of plastic box over them

    Sure - but you never mentioned inside, and the OP was taking about a connection on the outside.

    You'll need a box to cover the rear and mount the switches and probably an RCD. Not a sparky so ask one.

    You maybe want to earth the container as well.

    A bit like this, but they do have what passes for a cover.caravan socket.jpg
    This is a outlet wired by someone who thought they were a electrician but were mistaken.

    Best idea is to fix a small switch board which can be fixed across one of the inside valleys in wall. then fit the power inlet to the outside wall behind switchboard. that way it covers the terminals ( put a cover above switchboard so nithing can drop down behind it ). Then fit a RCD in board and connect those bunnings double pole GPO's. Best idea is to get sparky to connect all the bits but you can do the hard work beforehand.

    The OP also mentioned the inside:

    "...and something on the inside where I can plug in a couple of leads."

    Which is what I linked to.

    And Sparksy mentioned double pole outlets. Which, again, is what I linked to.

    Do you really think I'm so clueless that I'd recommend someone setup an arrangement that required a live male plug?

    Rather than use the common caravan type inlet I would go for a more substantial type. Some of the caravan type are pretty ordinary.

    At least everything is earthed.

    No of course not, but I wasn't thinking of you, but a newbie who stumbles across this and reads it the wrong way. If "inside" had been explicitly mentioned in your reply I would not have commented.
