Does this make sense ? What do you think.

I have a job to connect up a shed and greenhouse (socket in each) from a detached garage. House is TT and garage is fed via swa up garden.
I am unsure of the correct procedure re bonding in the greenhouse or not. I spent some time looking and could only find conflicting advice
and nothing specific within the regs.

I have already upgraded c/u with rcbo's on all circuits during loft conversion work.

So as I pay a considerable sum per annum to one of those scheme providers (no names but I like their biscuits) I contacted tech dept and asked should I seperate earth from house, put a rod in for the garage with a small c/u and 30ma rcd and then bond greenhouse, only 5M away from garage ?

I was told they would like to see greenhouse treated as a seperate zone, with its own rod and c/u and rcd within the greenhouse ! leaving the shed and garge with the house earth.

Has anyone put a consumer unit within an 10' x 6' aluminium greenhouse ?

I would appreciate some input from respected members who will know a great deal more than I..

i would just run cable to greenhouse and long as rcd protected and suitable enclosure for conditions , think ipx4 should be fine , if any two parts are at arms reach from eachother you could suplementry bond..

Pat Tester,

What i'm saying is that with a TT system, the more rod's you drive into the ground the better the Final Ra is going to be. If you connect the rods for the garage shed and greenhouse via a 3rd core of a SWA cable to the EMT at the garage CU the 3rd core of the supply SWA cable will take those Rod installations back to the MET. Use the SWA armouring as your CPC for the supply and distribution cables.

Personally, the shed and the greenhouse can both be supplied from the Garage CU on one or two radial circuits. As stated earlier nothing to stop you supplementary bonding the greenhouse metalwork to one of the sockets....

Depth n all eng........

IP4X in a greenhouse?, think about it! Watering plants, auto watering system etc.

Can't you just fit outdoor sockets outside the greenhouse that would solve any humidity problems.

No Veg.? Didn't you ever grow Camberwell Carrots in your greenhouse?
