    PME lost neutral and over voltages.

    Howdy folks. I have been reading a thread on another forum about PME and lost neutrals and one of the comments was this: Also: IET Forums - "give PME the boot" I can not see how losing a supply neutral would result in an over voltage. Has any one got any ideas? Thanks.

    PME & Metal Containers

    PME and exportng a supply to a metal container via a SWA. This has probably been talked about before, but how can you TT the exported installation when you are in a very sandy area. Can you just put notices up and rely on RCCB s for protection ?

    A good guide For 'exported PME' and outbuildings!

    For anyone bored by the constant myths and rumours regarding this subject, have a read of this guide from the IEE on supplies to detached outbuildings. It was published in 2005 but the important bits remain unchanged and might be of some help!
