This lamp column has fascinated me for about 2 years [yes, i know I need to get out more!!] Apart from no visible fuses it also has no isolation at ground level, I think the earthing is discontinuous and the 2 lamp heads are on different phases. Oh, I forgot to mention that this 'median strip' also doubles as a public footpath!!!
I will be back there in a few weeks; camera at the ready [Linked Image]
