I have a question.How do I get the Ze for my shed ? do I get it at the intake to the small consumer unit inside my shed then do the usuall Zs= Ze + (R1+R2)The source of supply is from a socket in the garden that is direct from the house CU RCD protected. or would I have to use the Ze from the house intake position. My shed is stand alone with a light circuit 6amp mcb and two radial circuits 20amp mcb all protected by RCD. another problem I have is if the shed CU trips the house Cu trips too. both protected by 30ma RCDs the garden sockets are 32amp mcb.

They are in series, on protective device downstream of another is series.

If you put one SP mcb after another it is series and you get the benefits of a series connection.
Put one DP mcb after another it is series,
Put one RCD after another it is series.

Current passes through one and then the other, if it was paralell then current would pass through each one without passing through the other.

Without seeing the installation I would say the ZE is taken at the incomer to your shed DB with the earth disconnected and on your cert marked down as ZE at the DB

That would be the Zdb or Zs. The Ze can only be 1 place can it not?

Cannot be arsed to read all the posts on this thread for obvious reasons.

One thing about this thread to some of you know it all type people it certainly caused some interesting results and varying options. Some helpful some sarcastic. We all have various interpretations of the rules and regulations but we are not infallible Is that not why we refer to our on site guides and BS7671:2008 (2011) or even the Electricians Forum. That is excluding the I'm too clever to part with my knowledge or experience. A joke is a joke but bugger a pantomime. Amature armature ha ha armadillos
Any advise on wiring a three pin plug from China from Ebay :fuk2:
