Pete I already have one and they are very handy checking things while power is on

Sorry pete999 I just noticed that the date was a long time ago. I can’t understand why the old post that goes back to last year is still on the list

I have two, why I don't know could be something to do with me being a tool tart I suppose. Looking for one that does magnetic detection as well roll on ELEX Coventry

Pete999 why do y’all have so much trouble finding a good earth ground. In about I read about earthing and z’s. I’m confused

Ze External Earth loop ZS the Earth loop at the circuit is the best I can explain Earth and ground to us is like chalk and cheese, where as you bang a stake in the ground and use that as ground, we tend to have lots of different Earthing syatems

Hope this vid will enlighten you

Thanks for the video it starting to make sense. The power company in the UK gives y’all 230vac on 1 wire and 0v on the other. Then y’all bond it at the service. In the USA the power company gives us 3 wires with 240 vac on 2 wires and the other wire is the 0v which we bond at the panel using 2 ground rods then you have 240vac phase to phase and 120vac from either phase to earth

What you are referring to as bonding the service is done by the power company.
If they are supplying the earth then they will provide live, neutral and earth connections.
If they are not supplying the earth then they will provide only live and neutral connections.

All low voltage supplies are supplied at 230V single phase or 400V/230V three phase (with the exception of the very rare split phase supply which is the same setup as your 120/240 except at 230V/460V)

The power company gives us 3 wires 2 hots and 1 bare wire, we take the bare wire and install a # 6 solid bare to it and take it unbroken with no splices allowed to two 10 foot ground rods that is a minimum of 6 feet apart and that’s how we bond the neutral and the can the breakers are in

No sir Dave the power company gives us the bare 3rd wire and it is our responsibility to do all the bonding and earthing

Am I confusing people when I refer the term bonding?

Yes I know that's what happens in your country, what I am trying to tell you is that in this country the thing you are referring to as bonding (connecting the neutral to the physical mass of the earth) is done by the power company.

At the substation the star point of the transformer output is connected to a network of earth electrodes which have been proved to have a very low resistance connection to the earth.

So are you telling me that we don’t have to earth since it’s done at the substation. Where I live the power lines is medium voltage at 7200 volts then it goes to a step down transformer at 240 vac phase to phase after that it comes to me I have to bond it again. Dave I’m trying to understand

Dave I watched Pete999 video where the power company gives y’all 2 wires 1 being 240vac and a 0v wire which it seemed the 0v wire y’all get and y’all have to earth it, is that correct

Dave I don’t know what the power company does at their substation, what I do know is what I have to do when the power company gives it to me

How many supplies are fed from each transformer?
Yes the star point is connected to earth at the substation, what happens after that depends on the type of supply. The resistance to earth of that connection is tightly regulated and will usually be well below 1 ohm.
The substation will usually have 11000V coming in and nominal 400/230 coming out.
For residential and small commercial supplies the substation will feed one, or usually multiple, distributing mains.
The distributing main is a large three phase cable running down the street usually underground or occasionally overhead.
Each single phase service is then jointed onto one of the phases of the distributing main, usually ever third house along a street will be connected to the same phase.

All connections of the neutral to earth are made by the power company. We are not allowed to connect neutral to earth in a consumers installation.

The 0V wire is the neutral, we don't connect this to earth.
The confusion is coming in because that is presumably describing a TNCS or PME supply.

The video talked about 3 different ways and one was TNCS-TNC-and something else with a T

Dave you said that y’all was not allowed to connect neutral to earth in consumers installations but in the USA we are required to bond the neutral to earth and it’s been done this way as long as I’ve been doing electrical. It must be me not understanding what you are trying to tell me

Yes there are three systems in common use, TNCS TNS and TT.
My replies so far have been based around a TNS to avoid confusing things further for the moment, maybe I should have focused on TNCS.

Yes in the USA (and many other countries) you are required to do that and in the UK we are required to not do that. (My personal opinion is that the USA approach to this is better)
I believe your system is a TNCS system (as far as I know this acronym is internationally used)

Dave I can’t thank you enough that’s been bothering me. I’m here to learn and was starting to feel like an ldiot. I’m not educated like y’all I had to quit school in the 9th grade to get a job to help my mom since I didn’t have a dad. I am not the best electrician out there but I’m not the worst either. I’m sorry if I made you mad. Please don’t have no hard feelings I don’t want to be kicked off this forum. It seems like I cause more trouble than anybody

Megawatt don’t panic or get worried you are our overseas companion and interesting to hear how you yanks do electrics in comparison to us British your terminology is different to ours but all do the same job. Keep posting and asking questions I’m on here for same reason to learn and expand understanding no harm in that ?
