The Scotland England difference

[scotsparky]

I known this may start a debate however its a good question.

I have just had a look at Mr Marks Sparks install in the "Show us your installs " tread and notice a difference. When i served my time in Scotland we had to put a lockring at every coupling,conduit joint. However i noticed mr MarkSparks had none on his conduit. Is this an English thing and if so why??

Tested containment at various points of install and all results were under 1 ohm so ok . RCBO s installed on ring mains and many parrallel earths so all good. Containment i suppose is primarily for mechanical protection. scotty

you suppose?? interesting answer On old PME systems the conduit /trunking was the earth a lot of those installations dont have RCDs so its vital you have a decent earth throught the metalwork, under 1 ohn isnt a very good reading there is it capain? it has to be a lo under near 0.05 ohms.

Dont rely on rcds as a get out for bad installs and desighn they are SUPPLIMENTARY fault protection.
