    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!

    exporting pme

    if (for arguments sake)you're exporting PME with a swa submain-not converting to TT can the 'main bond' be used as 'cpc' or should they be separate should the main bond be at least minimum csa required and kept to less than 0.05ohms thanks

    Who can install a PME system?

    Evening all, I was talking to a colleague today who was saying that if he couldn't get a good enough Ze reading from a TT system he would convert it to a PME. Can he do this?? Sorry again if this is a really basic question but I for some reason thought this was down to the supplier eg EDF Cheers
