    Are there any electric vehicle Charge points that can be used with PME?

    I am looking to fit a EVCP in the customers garage. The earthing system is PME although it would not be too hard to change the garage to TT. I have 3 questions. 1. Can the PME be used as long as the EVCP is located in the garage so that the car cannot be charged outside? 2. I believe there...

    DNOs forbid PME earth being exported???

    https://professional-electrician.com/technical/stroma-certification-supply-chain/ In the 1st paragraph of the above article, it states "some Distribution Network Operators (DNOs) may forbid their PME earth being exported from the supplied building.". I hear this repeated a lot, or "you must...

    Stick to TT or go PME?

    Ok, so you have an old non RCD protected domestic installation on a TT earthing arrangement. Would it be preferable to upgrade to PME if available by the DNO or stick to TT and protect with up front 100mA RCD if the Ze was ok via the rod?

    PME or not PME, that is the question?

    Noticed this near me ... I've got to assume it's a pme rod, but not connected. Maybe an old one that they are going to connect to the forthcoming branch off.

    New EV charger needs no Rod and can be used with PME

    I had an email this week from PodPoint. The new Pod Point Solo EV charger does not require an earth rod and can be used with PME. It has in built DC protection and complies fully with the 18th ed Regs. From what I can see and having done the online little training thing, it is brilliant. Taken...

    The hoary old topic of PME, TN-C-S and earthing rods (not TT)

    Somewhere along the line I picked up a suggestion from a forum posting or two that the DNO does not like you to connect an earthing rod to his "earth" - even though it is effectively just creating yet another, local to your installation, earthing point for the multiple ones already assumed to...

    Come across this on instagram this morning. Any thoughts? Dont have much experience of generators myself, In terms of this question my thoughts were additonal or secondary supply source with a rod skewing readings? Not sure though. Would somebody with experience of generators explain?

    Free PME upgrades. A common practice now??

    Enquired with NEDL about two possible TT upgrades to PME. I found the screenshot below on their website. It used to cost around 160 quid for the intake to be changed but now it's apparently free. Are other DNOs doing this? Has there been some legislative change?

    History of PME Systems.

    Does anyone know the history or reasoning behind PME and TN-C-S earthing? It came up today and I thought it was worth knowing. Why was it brought in and when?
