Just wanted to see if the following is the correct way to supply a socket in a greenhouse.
Firstly the supply is tn-s and the customer wants a socket in the greenhouse for a heater. Now the supply to the greenhouse would come from the shed supply as it’s on a separate circuit. I was thinking of:
Run 2 core 2.5mm swa from shed cu to greenhouse using armour as earth in supply cable.
Terminated cable into ip rated double socket.
Insulate gland at greenhouse end and fit earth rod to give an earth due to bonding to the greenhouse.
Fit rod and run 10mm earth into socket and also bond greenhouse at same time.
Is this acceptable in regards to the bonding?
