but otherwise I
see a problem. mine sits in the wooden propagator box in damp sand
cable is insulated and sealed. If it was to develop a fault in the
insulation then it would just trip the RCD anyway.
Only if the propagator itself is connected to earth.
And how would I earth a wooden propagator? :-)
The cable itself is earthed of course.
(though if you have mains electricity in a GH then yes I guess any metal
work such as staging etc. should be earth bonded
