Posted By Paul A. Swift We have a need to hire a couple of portakabin type units for use on a customers site, however I am unclear of the exact electrical testing requirements. I have spoken with a number of Hire companies, but I am not getting back consistent answers so wondered if anyone can help. Most of the Hire companies I have spoken to seem to be able to provide test certification covering the internal electrics of the cabins. However, some are saying that once the cabins are connected to an electricity supply, they will require re-testing. I am also concerned about the testing of the mains electricity supply connection, from wherever the supply cable it is connected (customers distribution board) to the portakabin itself. None of the hire companies I have spoken to seem clear on this, suggesting that perhaps, more often than not, this area is ignored and not tested at all. Any help / guidance on this would be much appreciated. In addition if anyone can confirm if this is just covered by the Wiring Regs BS7621) or if there are any other regulations that apply to this area, it would be greatly apprecoiated.

Posted By Kevin Kelly Paul, The installation is regarded as a permanent supply as it is connected to a consumer unit and therefore requires a RECI Cert. Any registered electrical contractor will be able to provide it. This cert is proof of a thorough examination of the system. All the above info can be found in the ETCI Regulations, the electricans Bible. Hopefully that should be of some benefit to you.
