This looks like a single street lamp unit is protected by a 32A

lower. (what are street lamps 400W?).

It may be a 25A or even lower BS88 fuse in the cutout though. Or
perhaps that's the last post in a line and they use the same unit on
every post for consistency.

2) Some have said (even on this NG), that its impractical to have a
EV charging point on street lamps as they don't have the current
carrying capacity.

Individual lamp posts may have capacity for a slow charger, but not a
charger for every lamp post. Maybe 10 or 20 posts on one 25A street
lighting circuit connecting in to the public mains.

The street lights around here are individually tapped off the feeds for
the houses.
The feeds are probably a few hundred amps.
There is no separate lighting circuit.
