WebMay 27, 2024 · I suspect @Dustydazzler was referring to the CPC size of the supplying circuit (e.g. if fed from from 4mm T&E then 2.5mm CPC, etc) Generally for smaller SWA sizes the CPC is fine, but there comes a point when the armour is no longer able to cope with the adiabatic stress due to the higher resistance of the steel. Reply to pc1966 1 2 Next WebJun 6, 2024 · You only need to know the maximum ZS Value in order to calculate the minimum CPC size required for a circuit, and yes when using the calculation it will nearly … the boop troop

WebJun 28, 2008 · jumboscruit New Member. 1.5 is the usual size of a cpc in a ring wired in 2.5. You could use 2.5 if you want to, as you are using singles. Some people do. The cpc on a 1.5 circuit is usually 1.0, and that is the size of the earth wire in 1.5 twin and earth. The earth wire in any twin and earth cable is always at least one size smaller. WebThe available TPS cables greater than 2.5 mm² all have stranded conductors. The CPC conductor used is always stranded. Standard UK metric twin and earth cable sizes. 1/1 mm² and 1.5/1 mm² have solid conductors and CPC 2.5/1.5mm² has a solid CPC and may have solid or stranded conductors http://www.china.org.cn/china/Off_the_Wire/2024-04/14/content_85229888.htm the boonton station 1904
