[QUOTE="Dairyspark, post: 397042, member: 19743"] On the topic of SY cable, I was once informed that SY cable does not conform to a BS standard only an EN standard so is that maybe why current ratings are not available in 7671? It is also to my understanding that the steel braid in SY cable offers very little mechanical protection and only serves the purpose of a screen, which leads me to another question, an SY gland connects the braid at both ends effectively forming an earthed sheath, however on the boats I work on any screening on cables is to be connected at one end only and the other end left open to avoid any current flowing along the screen, anyone have a my thoughts on this?
