2009年2月28日 · He is running armoured cable under the hedge of our garden. There is no fence so just under the hedge. What concerns me is that he does not feel the need to bury the cable. The question is - is it breaking any regulations to not bury it. It is visible, but unlikely
2006年2月1日 · The steel wire armouring cannot be relied on as a CPC. The use of the armouring is as a CPC is not allowed in the “regs” (BS7671). An external CPC is needed as the SWA is not big enough. An internal core is needed as a CPC as the SWA is not big enough. The SWA does not need to be earthed as it is not an exposed conductive part.
I've run a 16mm 3 core armoured cable to it and done the necessary calcs regarding voltage drop. and current carrying capacity etc. My question is this, At the supply end when jointing the SWA, can i run the cable through the masonry cavity wall. with no additional protection, ie conduit, or would I be better terminating the SWA outside in an ...

Aug 27, 2012. #1. I have a job comming up where I need to run power from the house to an outbuilding into a new consumer unit and then from this building to another where there will be a smaller consumer unit. I have completed my calculations and the cable leaving the house will need to be 25mm and then 16mm on to the second smaller con unit.
Location. cheshire/staffordshire. Oct 30, 2011. #2. the armour must be earthed at the source,as it is an exposed conductive part.whether it is used as earth for the installation it supplies is another matter.

2019年5月23日 · May 23, 2019. #9. There’s a diagram in the BBB somewhere showing the change in colours. Red turns to brown Yellow turns to black Blue turns to grey and Black turns to blue. If you were using 3 core in old colours it would be line red, cpc yellow and neutral blue. Just follow the diagram and black and grey are cpc and neutral respectively.
2020年5月9日 · May 9, 2020. #14. Ducting is the best option for you at the moment. As others have said without knowing the future loads etc it would be wasteful to install cable now as it may be the wrong size/type. Also cable prices vary, the price of copper is quite high at the minute.
Location. Bath/Bristol. Nov 21, 2013. #2. Reasons for putting dc through a long swa cable: - dc voltage likely to be higher than ac voltage, therefore current lower, therefore power loss lower for same size of cable. - no problem with ac voltage drop causing exterior inverter to cut out due to over-voltage.
