The work you are verifying is the DB replacement only. As such sufficient inspection & testing to demonstrate that this has been done properly, and does not impair the safety of the existing installation, and that the safety of your work is not impaired by the existing installation is what is...
I wouldn't necessarily agree with that. The trend towards smart metering is making this a real issue, and I would think the chance of pushback is growing all the time. Some DNOs are stricter about it than others. For some they will openly state that it must not be done. I suppose the bigger...
My view is that it shouldn't generally be done. Customer equipment is not permitted within a Permali Box. You are likely to be in breach of your supply agreement.
If it's an enhanced supply (16kVA) then there would be an 80A main overcurrent device. For 12kVA (standard supply) then there will be a 63A main overcurrent device. You shouldn't exceed this. The ESB's fuse rating is not relevant.
I would keep any socket-outlet below 1200mm but the screen/display (if there is one) a bit higher for readability. The Zappi comes with a mounting template with heights. Bear in mind that an EV chargepoint is classed as an appliance. Don't forget the rotary isolator.
It will (set at 63A if standard supply) if you run from the main DB. If you run from the garage DB then you'll need two CTs (though some would run the tails one from a Harvi, but I personally wouldn't).
Yes I have. CEF in Letterkenny stock the SWA version of it. Manufacturer's data quotes a 20mm gland for 6mm^2 with Cat 5 though it is fairly tight. Have also used the ProInstall version from Eland cables - not the SWA version in this instance. It has Cat 6 data and the conductors are much more...
PEN fault protection is a UK-only derogation from IEC and harmonised standards so isn't relevant. You could not wire this into the installation as having a switching device in a protective conductor is expressly prohibited. You must use an RCD which interrupts all live conductors (e.g. double...
Assuming the installation is neutralised, I would give a 2 to an Earth electrode which could not be located as it is impossible to verify that it is correct (or even present). A simple test doesn't prove this.
An S type (Selective) RCD is time-delayed. This is nothing to do with whether it's Type B, Type A, Type AC or whatever. So it can certainly be an S type with Type A RCD.
You're not correct though - you've mixed up the Earthing Conductor and the Main Protective Conductor ("neutralising link").
Earthing Conductor has a different meaning in I.S. 10101 to BS 7671.
As above, this is actually a serious criminal offence and carries heavy punishments including imprisonment. My only advice would be to stop and get this sorted correctly and in compliance with I.S. 10101.
The installation not being neutralised is dangerous.
Granted. My comment relates to how it was installed for the intended use. As such I don't believe that 32A was the correct choice. It is, however, ideal for a socket circuit.
There's no benefit to downrating the circuit protection if there's a 6mm^2 cable there. That said, I'm not a fan of an EVSE being connected to a 32A protective device rather than a 40A as otherwise it's running at the full rating of the protective device for potentially many hours at a time.
