This diagram shows the same TNCS installation but with the new wiring colours. It is also possible that the tails between the cutout, meter and consumer unit will have grey outer insulation, with blue or brown inner insulation. Caution. Just because the earth connects to the side of the cutout, this does NOT automatically mean it is a TNCS supply 2016 40 autumn wiring matters earth rods who needs them myenergi earthing systems fr 5076 electrical earthing diagram earthing systems Tn C S System Of Earthing Scientific DiagramTncs SupplyOf Earthing Arrangements Tnc Tn S Tt EepElectrical Installations Where Use Of Tn C S System Is ProhibitedTn C S Systems The Pen Conductor Acts As A Read More Â

TN-C- S. The latter is very common as it allows the single-phase loads to be supplied by phase and neutral with a completely separate earth system connecting together all the exposed conductive parts before connecting them to the PEN conductor via a main earthing terminal which is also connected to the neutral terminal TN-C-S power supply system. For the temporary power supply of the TN-CS system, if the front part is powered by the TN-C method, and the construction code specifies that the construction site must use the TN-S power supply system, the total distribution box can be divided at the rear part of the system TN-C-S jordningssystem: Kombinerad PEN-ledare frÄn transformatorn till byggnadens distributionspunkt, men separata PE- och N-ledare i fastinstallation inomhus samt hos flexibla kablar. PEN-ledare Àr en direktjordad ledare som har gemensam funktion som skyddsledare och neutralledare In a TN-S system both the neutral and protective conductors are separate within the supply and within the installation. Normally the means of earthing is provided from the supply cable metallic sheath or other separate supply conductor. In a TN-C-S system the neutral and earth are combined within the supply and separate within the installation TN-C-S system. A real danger can arise when the non-current-carrying metalwork of an installation is connected to the system's neutral, as is the case with a TN-C-S-fed system.The ground system is effectively in parallel with the neutral and can thus share the normal neutral current under certain conditions

What are the thoughts of you guys on the differences between a TN-S and a TNC-S (PNB) Earthing System. My understanding is as follows: TNC-S (PNB) - the Neutral & Earth Conductor are joined in the main switchboard with the neutral conductor between the transformer and the switchboard then being the earth fault path back to the transformer star point TN-C-S-System.

I've pulled the main fuse and there is a live & neutral supply, then the earth is taken from the neutral block (TN-C-S, right?). The problem I have is that I spoke to another electrician who seems to think that this shouldn't be the case if the supply is coming from overhead, as the system would need an earth rod, making it a TT system

A D32 MCB on a TN-C-S system would trip on the magnetic part of the trip if the internal cable was short but with TN-S a B32 MCB was largest that could be used. However with the blanket use of RCD's these advantages have now gone. ericmark, 25 Jun 2009 #7. Sponsored Links; ban-all-sheds. Joined: 27 Aug 2003 Messages A TN-C-S system (incorporating PME) cannot normally be used as it is not practicable to ensure that all extraneous-conductive-parts, On page 33 of BS7671 there is a couple of useful diagrams which would appear to make CNE TNC-S but not PME in this case as the transformer is the source of energy A systems diagram is similar to a flow chart although on first sight it is much simpler and more precise. The diagram is usually part of either, the ideas or development sections. However, do not restrict yourself to these two areas, if you feel it is necessary, use this type of diagram wherever you like in the design process

It is the Electricity Boards responsibility to provide a TN-C-S or a TN-S supply, if requested and available, it is not their responsibility to provide a TT earthing arrangement. In order for the Electricity Board to provide a TN-C-S supply, they have to construct their network to the standards of PME (protective multiple earthing), this is why a TN-C-S system is often referred to as a PME.

The decision to use TN-C-S was made a long time ago and whether we agree with it or not 'we are where we are'. TN-S is not some wonder system, it has disadvantages - one being that the earth path can fail and this could go unnoticed for years.

  2. Many of these will be a systems that have been converted at some point, e.g. an old TT system might have been converted TN-C-S, but the old earth rod was not disconnected. Earth impedances. The guideline figures that one uses in the absence of actual values, are 0.35 ohms for TN-C-S and 0.8 ohms for TN-S. In reality either can be significantly.
