Expecting I'll have to put it on the TT but here's the situation...
PME from the house connecting to the armour plus one core of outgoing SWA. Intending to terminate the SWA at a wiska box on back of the shed (outside), connect the armour to the cpc again and that earthing ends there (some would say overkill but honestly it's not much effort with those gland plates wiska makes), this box will be filled up with gel when I'm done with it. From here the L+N go directly into the back of a tiny shed CU/DB, which is on TT.
Now customer has just asked to have lighting going round the garden starting from the shed, but doesn't want to get the shed too 'busy'. I'm going to be taking power to these lights with SWA, and obviously I'm not going to have two separate earthing systems present in a single wiska box!! Rather I'm thinking I'll take the garden lighting out from the other end of the back of the shed (out of arms reach) if it needs to be on TT with the shed.
So my question is, am I going to have to say "sorry, but I need a few more boxes in here" or can I have the garden lighting leave the shed through the same box as the incoming supply and on the PME (except where it's inside the shed going to the switch ofc)?
Again, thinking it has to be the TT, but I don't have my book with me, yes I'm a right ---- for that, tin hat on!
