Electrical Wiring for a Welding Platform within the Oil Industry

Former Community Member

I was wondering if you could help us out has I'm presently working on a 4 Storey Platform for a project for the Oil and Gas Industry.



Now this Platform is basically for Welders to work on now there is a Power Source that is a Permanent Fixture in a building containing 110v,230v and 400v connections and these connect in a way like a long extension lead using Caravan type Hook-up Extension Leads to the 4 Storey Platform structure.



Cables used for this structure are for 110v Single Phase Neutral and Earth Cable (32A),230V 32A Single Phase Neutral and Earth Cable and for 400v this is 32A 3 phase Neutral and Earth Cable which connects to the Platform itself.Now the Lighting on the Platform is in the form of 26W LED Type Lighting of there are 3 sets  of these on each floor but my question is what type of cable would run the lights to power them up would it still be 110v 32a Single Phase Neutral & Earth Cable or would it be Twin & Earth 1.5mm2 Cable.And the Sockets for the office containment on the first floor would they be of 2.5mm2 or 4mm2 and not 230v 32A Single Phase Cable.I Can understand there is a interface connection for the Welding Equipment this being 230v Single Phase Neutral & Earth Cable Connection. So was wondering has to your thoughts on the sockets and the lighting on this structure?.

    Hi Alanblaby,

    Thanks for your help and ideas now all I really know about the wiring of this structure has the Spec is Vague,Is that the Power Soucre has three connections that seem like Caravan Hook-up Connections.

    Now these Power units are for 110v,230v and 400v so assume these ranges are all a requirement.I Believe the lighting circuit is hardwired to the Power Soucre but the spec is very vague.Now I Noticed on the 16kW Welding Machine the Spec asked for 239v Single Phase Neutral & Earth requirements but a max input current of 30A but I thought that the current would be higher with being 230v and not 400v but it did state it was a low Frequency Induction Welding Machine so whether this has something to do with low current but not sure.Now Sockete the Spec is Vague at first I thought 230v but with you stating 110v I didn't realise this could be used but can put this to the client has it is in an proposal state at present so there is a lot of questions being fed to the client.So if you have anymore new ideas I can collate them together has its a head thinking status part of the project cause there is a lot of vague information been given by the client.My guess with the 400v 3ph is for the Motor Starter for the Pump.Anymore ideas would be appreciated?,
