Student training aid for the different sizes in mm2 of twin and earth cables (PVC/PVC twin and CPC cable). This video includes the size of both live conductors line and neutral as well as the size of the often smaller CPC conductor (earth).
Please note that all conductor sizes are in mm2 as it's the area of the conductor.

  • Here in Germany the CPC is always insulated. CPC/PE has the same crossaction as the live wire it to 25mm2 but it is very uncommon. Standard cables have the same PE/CPC up to 240mm2. (NYY-J 5x240) Up to 10mm2 the wires are solid and as we use 3phase in domestic houses, 5x10mm2 with solid wires are very common. There are also some types of cables with solid wires it to 16mm2. In Austria and Switzerland wires with 10mm2 and more are straighted. The smallest crossaction available here is 1,5mm2. Also there is wide range of different cable types with more than 4 or 5 conductors. Eg NYM-J 7x1,5 or 12x1,5.

    • Same in Ireland. CPC is the same CSA as the other conductors and is insulated to the same thickness as the others.

    • Read the Onsite guide. Technically you can have whatever thickness (CSA) of cable you want so long as it can handle the current. There just happens to be a standard set of sizes to cope with certain common current requirements.

  • I read somewhere that said ‘ here is a standard 2.5mm2 cable’ and on the diagram it said the cross sectional area was 1.78mm. Is this right? Or is it actually 2.5mm2 on each conductor?

    @db-bv5rs@db-bv5rs3 жыл бұрын

    • Hi Daniel, 1.78mm is Copper conductor diameter for 2.5sqmm2 electric wire. 1.78*1.78*0.785=2.4872sqmm2 which nearly to 2.5sqmm2 So its actually 2.5sqmm2 on each conductor.

  • Hello. I need some help. My house garage door was wired 20g for the door opener. But I bought a new opener that was designed to use 22g. Which I didn't know before I bought it. If you can tell me how can I get it to work. It can't take the signal when I connected it. Can I use resistors to make it work?

    @mittonitto1234@mittonitto12344 жыл бұрын

    • You are getting mixed up. 20g, 22g refer to the thickness of the cables. The problem you might be having is fitting the thicker cable into the screw termination which is for a thinner cable. You don't solve that problem by using resistors.

      @deang5622@deang5622 Жыл бұрын

  • Not sure if this thread is still live, but when you say the diameter of the cable is 6mm (for example) are you talking about the combined diameter of the live and neutral cables. The cables idividually only appear to be about 3mm in diameter, which is why I ask. I'm having a 9.8kw shower installed and the cables (individually within the unit look about 5mm in size. (Which is why I ask.) Thanks.

    @donquixote3820@donquixote3820 Жыл бұрын

    • No. The diameter or CSA (in mm^2) relates to a single wire, either live or neutral. It is not the combined CSA of both.

    • Which country are you in? If you're in the UK you can't do electrical installation work without having the suitable qualification, and if you're asking a fundamental question on what the definition of CSA is, that suggests you are not adequately qualified, under UK requirements, to perform the installation.

  • If a house was a average 3 bedroom house would two bedrooms be wired with a 2.5MM cable and the last one with a 6MM because the room is a lot further away from the first socket point on a 32AMP breaker OR is the 50Metre max length of a cable per cable not from consumer unit to end of house (what I mean is from consumer unit to first socket then another cable from that socket to the next one should not exceed 50 metre per cable or is it from consumer unit until end socket in the 3rd bedroom socket)

    @CAR_SOLUTIONS@CAR_SOLUTIONS4 жыл бұрын

    • The standard lengths of the final circuits are based on using a particular CSA of cable to enable a specified maximum current to be carried. So 50 metres is the length of the entire cable length at the specified CSA in mm^2. If you want a cable length longer than that, then you need to increase the thickness of the cable, increase the CSA. It's down to you then, to do the calculations to determine what CSA you need. I would be careful mixing different CSA cables in a single final circuit, as you may end up overloading the cables of lower CSA. But you need to analyse the currents and decide on what CSAs are appropriate.
