So, according to AS 3000
5.3.2 Earthing conductor material and type 5.3.2.1 Conductor material 5.3.2.1.1 Copper conductors Copper earthing conductors shall be of high conductivity copper and shall be in the form of— (a) stranded conductors; (b) circular braided conductors; or (c) solid...
Doing some college work atm and come across a question asking me to provide an example of functional earth. I asked my boss at work but he doesn't even know what it is. The regs says " Earthing of a point or points in a system or in an electrical installation or in equipment for purposes other...
Hi all.
Reasonably competant non electrical engineer homeowner here. I have a question for the experts:
I recently replaced a horrible above-ceiling downlight connection with a proper Hager junction box. Whilst checking things generally I found my multimeter was reading a continuity between...
I am installing a Victron Quattro in an island mode configuration (in the UK, the DNO is the NG). I will be adding a stand-by generator. My property has a standard TN-C-S (PME) earth arrangement. I am an electrical engineer (testing) not an electrician. The regs state the DNO earth cannot be...
Hi I have a domestic installation to rewire and the main incoming fuse is 80 amp so i am using 16mm double insulated tails, is the main earth size with this 16mm or 10mm ? Thanks
I'm working on a system that has been installed incorrectly. It's a 3ph Hager board with 8 swa cables glanded into the bottom entry panel. The install is fine except the earth tag (banjos) haven't been fitted and they have relied on the metal plate as an earth. My question is, can you get a...
Afternoon all
I am looking for some advice as on what to with the suppliers earth after a conversion to a TT system.
Current issue is earthing arrangement is TNS, reading was nearly 60 Ohms, reported issued to DNO, they are effectively washing their hands of it as the (based on what the...
Can anyone tell me more about Twin and Earth American style?
What's it's full name? NM?
Is it always flat?
Do you add a sheath to the ground/earth cable?
Thanks 😊
Hi guys I'm looking for some advice. I have recently removed a wall socket that we no longer need, and have wrapped the individual Live, Earth and Neutral wires in electrician's insulating tape, and then wrapped the end of the whole cable in insulating tape, before cementing it back into the...
Hi, the new lights I have are metal and the earth connection doesn't connect to anything. I noticed the light that was there before someone had connected an earth to one of the bolts of the metal frame using a fork crimp. What would you do?
Hi
How do i access the earth rod to service it, where abouts will it be located and does a tt system have upfront rcds which will be probably in another enclosure?
cheers

Hi, I've got a light with a ceiling rose in the kitchen. While rectifying some faults in the house I came across to the light and measure Neutral to live: 240 volts (which is fine ofc) however when measuring earth to live I'm getting 150 volts. I have checked for any touched wires with my Fluke...
As the title says, I am looking for a recommendation for an enclosure and gland arrangement to electrically isolate or divorce the earth/armouring of a two core SWA supplying an outbuilding/shed. The supply to the property is overhead TT, so DNO provide phase and neutral only, a sub 20 ohm rod...
I found a picture online of a standard UK connection in a block of flats.
Where I have circled blue, would those earth clamps around the orange cable somehow cut into the neutral wire to connect within the orange sleeving?
Or are they just clamped to the sleeve for some arbitrary reason?
Hi all,
just looking for guidance on how you would code a 2.5mm main earthing conductor on a property with 10mm line conductor.
Basically on a massenette the one below has the incoming supply, and the one above I'm working in is looped supply off it the one below, 10mm tails in conduit with...
