    Voltage across neutral to earth

    No. He just explained the faulty test procedure I was doing which gave the voltage reading on neutral even once everything was disconnected. The original fault which caused the shock would most likely have been a loose neutral somewhere on the circuit. This was corrected even if we never found...

    NEED Legal advice - solar system malfunctioning

    The next step after going through their complaints procedure is to go through MCS and RECC. This is a lot cheaper then a solisitor.

    Solar earthing question

    The inverter casing will be connected to earth internally anyway. The PV modules can be earthed to an earth rod (not the main intake earth as the DNO don't like DC earth faults on their AC network). The earth isn't to protect against lightning strike, it'll be hopelessly small for the job. PV...

    Voltage across neutral to earth

    Thanks again everyone who posted. I really appreciate being able to get to the bottom of this.

    Voltage across neutral to earth

    Thank you mate. I'm really glad you could really understand my question. The capacitance of the disconnected neutral is the answer. I knew it was a flaw in the testing procedure but as I couldn't explain it like you I couldn't purseude the main electrical contractor.

    Voltage across neutral to earth

    That wasn't directed at you. Sorry if I wasn't clear. Me and the guys in the company have a laugh about the Trade Forum version of Godwin's law. "How many posts until the inevitable accusation of not being a genuine sparks/plumber/engineer etc"

    Voltage across neutral to earth

    Indeed I am. Does this mean you will now give a more technical response than your last 2 posts?

    Voltage across neutral to earth

    We can't do an insulation resistance test on the micro-inverters so the cable was dis-connected and terminated in a connector block.

    Voltage across neutral to earth

    Wilko, yes we went through all that. The Electrical contractor thought it might be to do with the LPS. But floating Neutral seems to be the key word here. I found a great article explaining it IET Forums - Floating neutral? -...

    Voltage across neutral to earth

    Focus people. I'm asking a specific electrical question not asking for judgment. If there are gaps in the explainstion then show your experience and ask specific questions. Murdoch- re read the OP. He switched off the circuit Suffolkspark: Re read the last line of the OP. Happy to give more...

    Voltage across neutral to earth

    Cheers for the comments so far. Happy to give more detail: Earthing: PME Testers: Fluke Multi-function and Ethos Multi-meter How he decided it was a fault on my circuit:He spent awhile disconnecting each lighting circuit, then switched off each MCB, my circuit was one of the last.

    Voltage across neutral to earth

    Hi I recently had a PV system we installed switched off after the Electrical Contractor got a shock off the Neutral. He was wiring lighting but after a processes of elimination found the fault was on our PV circuit. We did dead tests on the circuit Insulation resistance (1000v) Continuity...

    Stolen inverters

    Blinding mate. Can't believe he got his solicitor in. Once they're fitted they're his. All gear is now installed on delivery now for that reason. Pretty sure it was an inside job as it was a closed site, as in every trade was a pet company who'd worked with the main contractor for years.

    Raven Monitoring

    A tender document is asking for - "The system to have remote monitoring capable of sending data suitable for both Ravens monitoring purposes (to send to Raven) and for the purposes of the energy supplier paying the FIT send OFGEM requirements in an appropriate report format." I've never heard...

    House extension so need to remove and replace FIT installation

    I think British Gas, Eon and EDF have a secret competition to see who can be most obtuse. British Gas was winning (with a customer taking them to court for their delays meaning he missed a FiT drop), but Eon are about to over take (3rd set of forms a customer has been asked to fill out. Same...
