garden shed Ze

[£££sjim]

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.

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:

Well. Some of the so called know it alls clearly know more than you and you haven't answered the point about 2 rcd in series have you?

right I have been pondering this one and come up with the conclusion we are both right:stooge_curly: , if you look at RCD's they will be in series when in circuit runs through the rcd mcb through the load in series , correct , im happy with that , how ever close the contacts of the switch and mcb's the coils will then be in parallel ,and this is the reason i look at RCD's as being in parallel so the conclusion is rcd's are in the series parallel formation :stooge_curly:

It's in series. Numpty. From CU in house to socket in garden to a 13amp plug to shed then into shed CU and RCD and three MCBs. In my book Series. Can't be in parallel as the second circuit would start before first RCD ! Can't remove first RCD because it is protection for outside socket. But to be correct the shed should have had its own supply. But I knew this. So to be safe with the extenson feeding shed CU I wanted to check if there was a problem regarding Ze. So I received abuse from some NHs and some useful information from others. Also quite a bit of disagreement amongst your selves. ?.SELV ?

Look we all know you shouldn't install 2 RCDs of the same characteristics on the same circuit, we have done this to death 79 posts and still no settled, give it a rest

 

[£££sjim]

NO. ! Obvious this post has brought up many different ways to discuss certain aspects of installation that we all knew anyway didn't we ?

Know

You really don't get it do you? You don't have 2 rcd of the same value in the same circuit

In all honesty and fairness I will withdraw from this blog which at times has brought the best and worst in the Electricians Forum. Thanks boys and girls. See what I can use to wind up next.....train setting

forgive me if i've missed it, but is the shed wood, or is it metal. if the former it should make a decent bonfire. if the latter, use it as an earthing system ( buried, of course).
