In New Zealand on the older streetlight circuits ( early to mid 1970's ) no individual fuses were provided for the individual streetlights to save on costs.
A 32 or 63 Amp back up fuse was controlling the S.L. section at a whole, with a S.L. fault either the fuse blew or the wires blew clear of the choke or autotransformer in the S.L. fitiing.
The common practise we adopt now, If for any fault location or maintenance a non-fused older S.L. pole is encountered a 6 or 10 Amp HRC fuse is fitted to provide some close protection for the lamp and not take out the whole S.L. supply.
The newer S.L.'s are now these days all fitted with an HRC or MCB for individual protection. ( 1980's onwards )
We use a pilot system here fed from the substations via a master lightcell.
