    Doubling over conductors in ring circuit

    Was wondering. I haven't been to college for about 3 or 4 years now and I can't seem to remember what they said about doubling over conductors in a ring circuit. So in a ring circuit using 2.5mm twin and earth cable, is it recommended that you double over the conductors before terminating them...

    doubling cable over for termination?

    Working onsite with a few apprentices the other day and noticed that every cable they terminated into the mcb or rcbo was doubled over, so when I asked them why they were doing it there reply was college taught them to do it that way.

    Doubling up meter tails

    Just wondering what the regulations are on doubling up meter tails? My girlfriends dad wants to convert the garage into a 'granny flat', and I plan on doubling up the connections in the meter to take a new 16mm supply to the garage. Opinions?

    Earth doubling up as neutral conductor

    Good morning all, I was called out to diagnose a fault with some 2d robus light fittings. After some research it turned out the installers had programmed the PIR with the wrong time sequence (5mins) the tube and ballast were both being damaged as min run time should be 15mins. What stumped me is...

    'doubling' up on mcb's

    Doubling up busbars

    Came across a consumer unit last week where someone had lengthened the busbar by doubling it up - i.e a five way bus bar clamped into the RCD then three MCBs on single prongs then two MCBs on two prongs then three more on singles. It seemed mechanically sound i.e a good connection but is it...

    Doubling up conductors

    Is it an exceptable method to double up conductors in a 4 core cable to increase the CSA and then put in a seperate CPC? If so, then as there are no tables for doubled up sizes eg. 5mm, 8mm squared etc, would it just be a case of doing the calcs for the single core size then dividing by 2:confused:
